## What Are Freeze Dried Garlic

Freeze-dried garlic is produced by converting fresh garlic into a durable, easy-to-use and versatile product through a process called freeze-drying or lyophilization. Freeze drying involves freezing the garlic and then drying it under vacuum. During the process, the frozen water in the garlic sublimates directly from solid to gas and the garlic becomes durable.

Freeze drying helps to preserve the flavor, aroma and nutritional properties of fresh garlic while extending its shelf life. The resulting freeze-dried garlic has a light and crisp texture and can be easily rehydrated by adding water or used directly in a variety of culinary applications. It is widely used as a convenient alternative to fresh garlic in cooking, seasoning and food preparation because it offers a long shelf life and retains much of the flavor and nutritional value of the original garlic.

## Freeze Drying vs Different Drying Techniques for Garlic

Garlic can be made durable by different methods such as freeze drying, dehydration and microwave drying. However, the drying method used has a significant effect on the colour, taste, odour and biological properties of the final product. In general, freeze drying method provides better colour, aroma and flavour compared to alternatives.

In a previous [study](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7174234/), the volatile compound profile of freeze-dried and dehydrated garlic and antibacterial activity against different bacteria were compared. The results showed that the amount of allicin, the main volatile compound of garlic, was higher in the freeze-dried sample. Furthermore, dehydration caused significant color change and the final product was more brown. Finally, the antibacterial activity of freeze-dried garlic powder was much better than the dehydrated product. Therefore, the authors claimed that freeze-dried garlic can be used as a natural preservative in foods.

A [study](https://koreascience.kr/article/JAKO199003041954044.page) compared flavor differences between dehydrated and freeze-dried garlic powder based on volatile compounds. The study revealed that diallyl disulfide, an important compound of garlic, was most abundant in freeze-dried garlic powder. However, all dried garlic powder samples in the study had lower diallyl disulfide content compared to raw garlic.

Acrylamide is a compound formed during the heating of food. It is neurotoxic and potentially carcinogenic to humans. In one [study](https://pubmed.ncbi.nlm.nih.gov/36010398/), freeze-dried garlic was found to have a higher ability to inhibit acrylamide formation than oven-dried garlic. The authors explained this finding by the higher allicin content in freeze-dried garlic.

In a [paper](https://www.tandfonline.com/doi/full/10.1080/09603123.2023.2266393) published in 2023, the total phenolic content, total flavonoid content and antioxidant activity of freeze-dried garlic were found to be higher than dried ones. Furthermore, fresh, freeze-dried and dehydrated garlic were added to extra virgin olive oil to obtain aromatic oil. The aromatic oil obtained with freeze-dried garlic had better chemical properties and antibacterial activity compared to fresh and dried samples.

Researchers from China [compared](https://www.sciencedirect.com/science/article/pii/S0308814620322664?via%3Dihub) 5 different drying techniques to produce dried garlic slices. Results showed that freeze dried garlic slices had the highest whiteness, the least shrinkage, the least hardness, and the lowest rehydration capacity. Also, showed much different volatile flavour than heat-involved drying techniques.

### Health Benefits of Freeze Dried Garlic

Although there have been a few studies on the health benefits of freeze-dried garlic, fresh garlic and garlic extracts are one of the most studied foods. Since freeze-drying causes little change in the chemical properties of garlic, it can be argued that freeze-dried garlic may have similar health benefits to fresh garlic to a certain extent.
The studies showed that garlic has several biological activities such as;

- Antibacterial activity
- Antifungal activity
- Antiviral activity
- Anti-Protozoal Activity
- Anticarcinogenic activity
- Antioxidant activity
- Anti-inflammatory activity
- Antidiabetic activity
- Renoprotective activity
- Anti-atherosclerotic activity
- Antihypertensive activity

Thanks to these effects, garlic increases immunity and offers beneficial effects in various diseases such as blood sugar, blood lipids, blood pressure, cancer, and obesity. It also increases the safety of the foods to which it is added due to its antimicrobial effect and provides a longer shelf life.

## How To Make Freeze Dried Garlic: Step-by-step guide

For production of a freeze dried potatoes you will need a bunch of supplies are needed.

- Freeze dryer
- Freezer
- Pots
- Cutting board
- Knife
- Colander
- Trays
- Parchment paper
- Mylar bags or mason jars
- Oxygen absorbers
- Cutting board (for slicing)
- Blender (for pureeing)

### Step 1: Raw Material Selection

To make freeze-dried garlic of good quality and high flavour, the best option is to use fresh garlic. But fresh garlic is not your only option. You can also use processed products such as garlic puree, canned garlic and minced garlic. However, since these products are heat processed, their aromatic properties will be weaker than those produced from fresh produce.

### Step 2: Peeling and Pre-treatments

Start by peeling the outer skins off the garlic cloves. Although garlic cloves can be freeze-dried directly, slice, chop or crush them for best quality and more health benefits.

While mincing or mashing the garlic will impart the strongest flavor, slicing or roughly chopping will be moderate. On the other hand whole or lightly crushed garlic cloves will result with a subtle, sweet flavor.

In terms of health benefits, crushing garlic allow an enzyme called alliinase to work. A scientific [study](https://pubmed.ncbi.nlm.nih.gov/17256959/) showed allowing crushed garlic to stand for 10 minutes enhance formation of healthful organosulfur compounds which have different biological activities. Therefore, my advise to use chopping, slicing or mincing the garlic before freezing.

For different aromatic profiles, you can pre-treat garlic before freeze-drying, such as sautéing or roasting.

Freeze-drying garlic directly without any pre-treatment provides a strong garlic flavor similar to fresh garlic, while roasting garlic provides a milder flavor. On the other hand, sautéing provides a pungent and nutty flavor.

### Step 3: Freezing

Put garlics on trays lined with parchment paper (do not use silicone sheets as they absorb the aroma and will not release it easily). Spread the garlic as much as possible on the tray will enhance drying performance. Pay attention to your freeze dryer's capacity.

The freezing step can be executed in a freeze dryer or using an external freezer. When utilizing an external freezer, put the trays inside of the freezer and wait between 2-8 hours until the products are thoroughly frozen.

### Step 4: Freeze Drying

For pre-frozen garlics, initiate your freeze dryer 30 minutes before commencing the process. First, close the drain valve! Select the properties of your raw material (pre-frozen or unfrozen) in the dryer software you are employing. The software will provide guidance, and the dryer will initiate.

When the temperature descends to 32ºF (0ºC), the software will prompt you to place the trays. Insert the trays and select to proceed with the process. Generally, drying will conclude within 16-24 hours.

Inspect the products upon completion of drying. To do so, take the thickest items, cut them in half, and check for coldness or moisture in the center. If present, extend the drying process by a few hours; if not, stop.

### Step 5: Packaging and Storage

Package the freeze-dried garlic in airtight bags, vacuum-sealed containers, or other suitable packaging materials to maintain their freshness and prevent moisture reabsorption. Since it is used in small amount, make sure to use small packaging to prevent spoilage of remaining materials.

Label the packages with the date of freeze-drying and any other relevant information.

Store the freeze-dried garlic in a cool and dry place away from direct sunlight. They can remain edible for an extended period, from several years to 3 decades, if stored properly.

## How Long Do Freeze Dried Garlic Last

Freeze-dried garlic has an extended shelf life compared to fresh or preserved garlic. When stored properly in airtight containers in a cool, dry place away from moisture and sunlight, freeze-dried garlic can last for a very long time—often up to 30 years.

The longevity of freeze-dried garlic is due to the removal of moisture during the freeze-drying process, which inhibits the growth of bacteria, molds, and other microorganisms that typically cause food spoilage and limits the chemical reactions. However, this requires that there is no change in the moisture and oxygen-proof properties of the packaging.

After opening of the packaging, freeze dried garlic are susceptible to environmental conditions. Particularly in humid environments, they rapidly absorb moisture, leading to a soft and sticky texture. This process also accelerates chemical and microbiological reactions.

## How To Rehydrate Freeze Dried Garlic

Rehydrating freeze-dried garlic is a simple process that restores its original texture and flavor, making it similar to fresh garlic. Here's how to rehydrate freeze-dried garlic:

- Determine the amount of freeze-dried garlic you need for your recipe.
- Place the desired amount of freeze-dried garlic in a bowl or container. Add enough (1.25 fold of garlic weight) warm water to completely submerge the garlic. The water should be at a temperature that is comfortable to touch but not boiling.
- Allow the garlic to soak in the warm water for about 5 to 10 minutes. The warm water will gradually rehydrate the garlic and restore its original texture.
- Occasionally stir the garlic to ensure even rehydration. Check the garlic's texture and add more water if needed. It should become plump and soft.
- Once the garlic is fully rehydrated and has a texture similar to fresh garlic, drain any excess water. You can use a strainer or gently press the garlic to remove excess moisture.
- If necessary, pat the rehydrated garlic with a paper towel to remove any remaining moisture.
- Rehydrated garlic is now ready to be used in your recipe just like fresh garlic. Incorporate it into soups, stews, sauces, stir-fries, or any other dish as needed.

Freeze Dried Garlic: How to Make & Use


## What Are Freeze Dried Potatoes

Freeze-dried potatoes are potatoes that have undergone a process called freeze-drying. This preservation technique involves freezing the potatoes and then removing the water content through sublimation, where ice transitions directly into water vapor without going through the liquid phase. This process helps retain the shape, taste, and nutritional value of the potatoes while allowing for long-term storage.

Freeze dried potatoes offer numerous advantages over products preserved using other techniques like dehydration:

- **Physical quality**: Freeze drying provides better physical properties in terms of shrinkage, color and rehydration. In a study, porosity of freeze dried potatoes was [much higher](https://www.tandfonline.com/doi/abs/10.1080/07373939708917369) than other drying techniques such as vacuum drying, microwave drying, osmotic drying and dehydration.
- **Chemical safety**: Freeze dried potatoes contains less content of HMF and acrylamide since it is a low temperature process.
- **Shelf life**: Freeze-drying offers a much longer shelf life, making freeze-dried potatoes an ideal choice for long-term storage, emergency preparation and outdoor use.
- **Sensory properties**: Freeze drying causes minimal change in taste, flavor and aroma due to the application of low temperatures. Therefore, fresh potatoes can easily be replaced by freeze dried potatoes in almost all recipes.
- **Easiness of use**: Freeze-dried potatoes do not require any pre-treatment such as washing, peeling and boiling. This reduces the preparation time of potato-based recipes. It can also be used in many different formulations as seen later in this guide.
- **Convenience**: Freeze-dried potatoes are lightweight, easy to store, and convenient to use. They don't require refrigeration and can be rehydrated quickly by adding water, making them a convenient option for both home and outdoor cooking. In a [study](https://www.mdpi.com/2304-8158/10/5/1115) pasting properties of freeze dried samples were found to be much higher than dehydrated potatoes. It means that freeze-dried potato powder provided higher viscosity at the same concentration.

## How to Make Freeze Dried Potatoes

### Supplies needed

For production of a freeze dried potatoes you will need a bunch of supplies are needed.

- Freeze dryer
- Freezer
- Pots
- Cutting board
- Knife
- Colander
- Trays
- Parchment paper
- Mylar bags or mason jars
- Oxygen absorbers
- Cutting board (for slicing)
- Blender (for pureeing)

### Step 1: Raw Material Selection

The most important step in achieving a good quality end product is to use high-quality raw materials. Therefore, choose high quality, fully ripe and unsprouted potatoes.

If you plan to use freeze-dried potatoes in the production of various dishes, I recommend choosing a starchy variety.

### Step 2: Washing, Peeling and Cutting

Potatoes need to be washed thoroughly because they grow in the ground. For this purpose, wash the potatoes thoroughly under running water.

Then, depending on your preference, remove the skin from the potatoes with a peeler.

If you are going to dry them in slices or cubes, cut the potatoes according to your preference. If you are drying them as mashed, you can cut the potatoes smaller to shorten the blanching time.

### Step 3. Blanching and Mashing

The main aim of the blanching is to inactivate the enzymes in potatoes. If not blanched, the enzyme, polyphenol oxidase, present in potatoes cause browning during freeze drying. Therefore, blanching is a must for freeze drying of potatoes. In addition to enzyme inactivation, blanching significantly [increase](https://www.sciencedirect.com/science/article/pii/S0260877410002797) the rehydration capacity of the freeze dried potatoes.

The blanching process can take between 1 and 15 minutes depending on the size of the potatoes. Thin slices can be blanched for one minute, while large pieces or whole potatoes need longer periods such as 15 minutes.

Blanched potatoes become soft and suitable for mashing. If you are aiming for potato powder or flakes, mashed potatoes are your best option. To do this, use a potato masher to ensure that the potatoes are completely mashed.

### Step 4: Freezing

After cooling, put potato slices, cubes or purees on trays lined with parchment paper, which simplifies cleanup. Overlapping the potatoes is acceptable, but pay attention to your freeze dryer's capacity. Nonetheless, spreading them out as much as possible on the tray will enhance drying performance. For mashed potatoes adjust the spread thickness about 0.2 inches (5 mm).

The freezing step can be executed in a freeze dryer or using an external freezer. When utilizing an external freezer, put the trays inside of the freezer and wait between 2-8 hours until the products are thoroughly frozen.

### Step 5: Freeze Drying

For pre-frozen mangoes, initiate your freeze dryer 30 minutes before commencing the process.

First, close the drain valve! Select the properties of your raw material (pre-frozen or unfrozen) in the dryer software you are employing. The software will provide guidance, and the dryer will initiate.

When the temperature descends to 32ºF (0ºC), the software will prompt you to place the trays. Insert the trays and select to proceed with the process. Generally, drying will conclude within 20-24 hours.

Inspect the products upon completion of drying. To do so, take the thickest items, cut them in half, and check for coldness or moisture in the center. If present, extend the drying process by a few hours; if not, stop.

### Step 6: Packaging and Storage

Package the freeze-dried potatoes in airtight bags, vacuum-sealed containers, or other suitable packaging materials to maintain their freshness and prevent moisture reabsorption.

Label the packages with the date of freeze-drying and any other relevant information.

Store the freeze-dried potatoes in a cool, dry place away from direct sunlight. They can remain edible for an extended period, from several years to 3 decades, if stored properly.

<YoutubePlayer id="20XcXqmbzX4" title="How to make freeze dried potatoes" />

## How Long Do Freeze Dried Potatoes Last

Freeze dried potatoes have a a significantly extended shelf life compared to dehydrated counterparts. When appropriately stored in an airtight container, freeze dried potatoes can remain viable for up to 25-30 years.

Once the packaging is opened and the contents are exposed to air and moisture, the shelf life decreases. However, properly resealed and stored freeze-dried potatoes can still last quite a long time.

After opening, freeze dried potatoes are more susceptible to environmental conditions due to their unique microstructure. Particularly in humid environments, they rapidly absorb moisture, leading to a soft texture. This process also accelerates chemical degradation reactions. Therefore, it's best to use within a shorter timeframe.

## Nutritional Facts of Freeze Dried Potatoes

Freeze dried potato is rich in starch. According to a scientific study, starch content was determined as 72.6% for blanched freeze-dried potatoes. Moreover 100 g of freeze dried potato contained 104.6 mg of vitamin C which is slightly higher than recommended daily intake.

## How To Rehydrate Freeze Dried Potatoes

Rehydrating freeze-dried potatoes is a simple process that restores them to their original texture and taste, making them suitable for use in a variety of dishes. Here's a step-by-step guide on how to rehydrate freeze-dried potatoes:

1. Begin by heating liquid to a near-boiling temperature. You can use water, milk, soaps or bone broth to rehydrate the freeze-dried potatoes. The liquid you choose will impart flavor to the potatoes, so choose according to your recipe and taste preferences.

2. Transfer the desired amount of freeze-dried potatoes to a heatproof bowl. The quantity will depend on your recipe and the number of servings you intend to make.

3. Carefully pour the liquid over the freeze-dried potatoes, ensuring they are completely submerged. The ratio of water to potatoes can vary, but usually freeze-dried potatoes can take up to 6 times the liquid.

4. Let the freeze-dried potatoes soak in the hot liquid for about 10 to 15 minutes. During this time, the potatoes will absorb the liquid and begin to rehydrate.

5. Gently stir the mixture occasionally to ensure even rehydration. Check the consistency of the potatoes as they rehydrate. If they are still too firm, allow them to soak for a few more minutes.

6. After the potatoes have fully rehydrated and reached the desired texture, you can drain any excess liquid if needed. This is especially useful if you plan to use the potatoes in recipes where you don't want excess moisture.

7. The rehydrated potatoes are now ready to be used in soups, stews, casseroles, or any other dish that calls for potatoes. Incorporate them as you would with fresh potatoes, adjusting seasoning and flavors as needed.

Rehydrated freeze-dried potatoes maintain their nutritional value and can be used just like fresh potatoes in a wide range of culinary applications. Always adjust the rehydration time and liquid amount based on your specific recipe and desired potato texture.

## How to Use Freeze Dried Potatoes

Freeze-dried potatoes are a convenient and versatile ingredient that can be rehydrated and used in a variety of dishes. Here's how you can use freeze-dried potatoes:

**Rehydrating Freeze-Dried Potatoes**: Place the desired amount of freeze-dried potatoes in a bowl. Cover the potatoes with hot water, ensuring they are fully submerged.

Let them soak for about 10-15 minutes, or as directed on the packaging, until they are soft and plump. Drain any excess water and pat the potatoes dry with a paper towel before using.

**In Soups and Stews**: Rehydrate the freeze-dried potatoes as instructed above. Add them to soups, stews, or chowders to enhance flavor and add a hearty texture. They can provide substance and thickness to the dish.

**In Casseroles and Pot Pies**: Rehydrate the freeze-dried potatoes and incorporate them into your favorite casserole or pot pie recipes. They add a potato element and absorb the flavors of the dish.

Freeze Dried Potatoes: How to Make & Use


## What Are Freeze Dried Mango

Freeze dried mangoes are regular fruits that have undergone a special preservation process known as "freeze drying" or "lyophilization". This is an intricate process, involving the mangoes being quickly frozen and then placed in a vacuum chamber. The method retains the fruit's essential nutrients and flavor, but removes all the water content, leaving a light, crunchy, and refreshingly sweet snack.

The mango freeze drying process is unique in that it allows the fruit to maintain its original shape and color, even after all the moisture has been extracted. This makes freeze dried mangoes not only a convenience for hikers, astronauts, and athletes, but also an appealing, healthier alternative to conventional chips or sweets. The process ensures a longer shelf life and makes distribution and storage significantly easier and more eco-friendly.

Freeze dried mangoes offer numerous advantages over products preserved using other techniques like dehydration:

- **Physical quality**: Freeze drying provides physical properties like minimal shrinkage, negligible discoloration, and superior rehydration ability compared to other methods.
- **Nutritional quality**: Freeze drying involves very low temperatures, resulting in minimal loss of vitamins and other health-beneficial compounds of mangoes.
- **Chemical safety**: Scientific studies showed that mangoes preserved using freeze drying cause much less formation of heat-induced toxic compounds such as HMF and acrylamide.
- **Shelf life**: Freeze dried mangoes have a considerably longer shelf life compared to alternative methods.
- **Sensory properties**: The compounds that provide the unique sensorial properties of mango are sensitive to heat. Therefore, heat treatments cause a change in this aroma and flavor. However, freeze drying causes minimal change in flavor and aroma due to the application of low temperatures.
- **Diversity of use**: Freeze-dried mango can be consumed directly as a snack or used in various desserts and drinks. It can be used easily in granolas, oatmelas, cakes, smoothies and cocktails.

## Freeze Drying vs Different Drying Techniques for Mangoes

In a scientific [study](https://www.scielo.br/j/cta/a/HyPmtMS8pxMkSJvPkDCk9Fw/), freeze-drying, dehydration and microwave drying were compared for mango drying based on color, antioxidant capacity and total phenolic content. While freeze-dried mangoes had similar color characteristics to fresh samples, both dehydration and microwave drying caused significant color change. The antioxidant capacity of freeze-dried mangoes was much higher than that of dehydrated and microwave-dried samples. On the other hand, the total phenolic content of freeze-dried mangoes was the second highest after microwave drying at 350W.

In another [study](https://www.tandfonline.com/doi/full/10.1080/07373937.2020.1777562), researchers compared the physical quality of mango powders produced with cast-tape drying, freeze drying, and spray drying. The results showed that, freeze drying provided better solubility and color properties.

Researchers from Taiwan [studied](https://www.sciencedirect.com/science/article/pii/S0308814605009684) the effect of drying techniques and (freeze drying and hot air drying) and pre-treatments (no pre-treatment, soaking in in 1% NaHSO3 and soaking in 1% ascorbic acid) on the carotenoids content of mangoes. Their results showed that freeze dried mangoes contain all-trans-β-carotene, neochrome, violaxanthin, zeaxanthin, luteoxanthin, neoxanthin and lutein. Freeze drying and soaking in NaHSO3 as pre-treatment provided highest content of total carotenoids. Also soaking in both solution caused better color properties in freeze-dried mangoes.

## Are Freeze Dried Mango Beneficial for You

Yes, freeze-dried mangoes are packed with vitamins, fiber and antioxidants, all of which contribute to supporting overall health.

As a rich source of Vitamin C, it supports the immune system, aids in iron absorption, and reduces heart disease risks.

Dietary fiber, present in substantial quantities in dried mangoes, promotes digestive health and aids in weight management.

The antioxidant content combats harmful free radicals, reducing inflammation and slowing down the aging process. So, with a myriad of health benefits, freeze dried mango undeniably paints a positive picture in the context of nutrition.

## Scientific Studies on Health Benefits of Freeze Dried Mangoes

Only a few studies have determined the effects of freeze-dried mango consumption on blood glucose and lipid levels.

A pilot [study](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4155986/) examined the effects of freeze-dried mango supplementation on anthropometrics, body composition, and biochemical parameters in obese individuals. Results showed that freeze-dried mango supplementation significantly reduced blood glucose levels in both male and female participants. Freeze dried mango consumption also led to a reduction in hip circumference in male participants.

Another [study](https://pubmed.ncbi.nlm.nih.gov/21733317/) investigated the effects of dietary supplementation of freeze-dried mango, fenofibrate (a hypolipidaemic drug), and rosiglitazone (a hypoglycaemic drug) on adiposity, glucose metabolism, and lipid profile in mice fed a high-fat diet. The results of the study showed that freeze-dried mango, similar to fenofibrate and rosiglitazone, protected against high-fat diet-induced increase in epididymal fat. It was also observed that freeze-dried mango consumption at the 1% level was more effective than rosiglitazone in reducing blood glucose.

An in vitro [study](https://ifst.onlinelibrary.wiley.com/doi/full/10.1111/ijfs.13408?casa_token=-PJtMHVdk2UAAAAA%3AfD7lJZ52UsF8ROAA14d4stUFgLetP9H0ih0r3N8xxGWXVQMxXzmmNd7MNq6PjA4so_dqbit22b1A_gu9) has shown that freeze-dried mango is a suitable (ready-to-eat) functional food that may help prevent some carcinomas.

## How to Make Freeze Dried Mango

### Supplies needed

For production of a freeze dried mangoes you will need a bunch of supplies are needed.

- Freeze dryer
- Freezer
- Knife
- Colander
- Trays
- Parchment paper
- Mylar bags or mason jars
- Oxygen absorbers
- Cutting board (for slicing)
- Blender (for pureeing)

### Step 1: Raw Material Selection

The most crucial step in producing high-quality freeze dried mangoes is to utilize premium raw materials.

Although you can use frozen mangoes as raw material, using fresh mangoes will be more cost-effective. If you are using frozen mangoes, you can proceed directly to step 3.

It is advisable to opt for fully ripe and organic mangoes for drying, whether using fresh or frozen raw materials. Freeze drying of unripe mangoes will result in a tart and more acidic end product.

### Step 2: Washing, Peeling and Cutting

The use of pesticides is not common in mango production. The protective skin is thick and easy to clean. Therefore, mangoes that are thoroughly cleaned with water should be peeled.

<YoutubePlayer id="yE0NGXZ_HBs" title="How to peel mangoes" />

Peeled mangoes can be dried as slices, small cubes or puree. Generally, slices with a thickness of 0.12-0.16 inches are more preferable in terms of drying time and tooth resistance during eating. A uniform thickness during slicing is essential for a uniformly dried product. A fruit slicer can be used for this.

Cubes of around 0.2 inches are more suitable for consumption.

A blender should be used for pureeing. Puree drying is preferred in the production of powdered products. To do this, place the sliced mangoes in a blender and run the blender until a fine pulp is obtained. Whether the mixture is thick or viscous is not important for drying. The pulp should be spread in trays with a uniform thickness (preferably around 0.2 inches).

### Step 3: Freezing

Put mango slices, cubes or pulps on trays lined with parchment paper, which simplifies cleanup. Overlapping the mangoes is acceptable, but pay attention to your freeze dryer's capacity. Nonetheless, spreading them out as much as possible on the tray will enhance drying performance.

The freezing step can be executed in a freeze dryer or using an external freezer. When utilizing an external freezer, put the trays inside of the freezer and wait between 2-8 hours until the products are thoroughly frozen.

### Step 4: Freeze Drying

For pre-frozen mangoes, initiate your freeze dryer 30 minutes before commencing the process.

First, close the drain valve! Select the properties of your raw material (frozen, unfrozen, liquid, solid, etc.) in the dryer software you are employing. The software will provide guidance, and the dryer will initiate.

When the temperature descends to 32ºF (0ºC), the software will prompt you to place the trays. Insert the trays and select to proceed with the process. Generally, drying will conclude within 20-24 hours. This encompasses freezing, initial drying, and secondary drying.

Inspect the products upon completion of drying. To do so, take the thickest items, cut them in half, and check for coldness or moisture in the center. If present, extend the drying process by a few hours; if not, stop.

### Step 5: Packaging and Storage

Once freeze drying is finished, separate the mangoes from the parchment paper. Store them in airtight jars and mylar bags. To counter oxygen-induced reactions, introduce an oxygen absorber and seal the packaging.

## How Long Do Freeze Dried Mango Last

Freeze dried mangoes have a significantly longer shelf life compared to mangoes preserved using other methods such as dehydration. When appropriately stored in an airtight container, freeze dried mangoes can remain viable for up to 25-30 years.

This extended shelf life is a result of the complete removal of free water and the partial removal of bound water during the freeze drying process. This removal inhibits both microbial and chemical reactions.

However, freeze dried mangoes are more susceptible to environmental conditions due to their unique microstructure. Particularly in humid environments, they rapidly absorb moisture, leading to a soft and sticky texture. This process also accelerates chemical degradation reactions.

To prevent this outcome, it is essential to store them in a cool, dry place, away from direct sunlight.

## Nutritional Facts of Freeze Dried Mangoes

Among freeze-dried fruits, mangoes stand out not only for their taste but also for their nutritional value. The freeze-drying process ensures that the mango's nutritional properties are preserved almost unchanged. The dried slices contain high amounts of dietary fiber and vitamin C. They also contain vitamin A, calcium, and potassium.

According to the [USDA](https://fdc.nal.usda.gov/fdc-app.html#/?query=freeze%20dried%20mango) database, the nutritional values of three different freeze-dried mango brands are as follows

| Properties        | Brand 1 | Brand 2 | Brand 3 |
| ----------------- | ------- | ------- | ------- |
| Energy (kcal)     | 333     | 357     | 389     |
| Proteins (g)      | 0       | 3.57    | 5.56    |
| Lipids (g)        | 0       | 1.79    | 0       |
| Carbohydrates (g) | 90      | 89.3    | 88.9    |
| Fibers (g)        | 10      | 10.7    | 5.6     |
| Calcium (mg)      | 67      | 71      | 28      |
| Potassium (mg)    | 167     | 1000    | 639     |

The vitamin C content of freeze dried mangoes was [reported](https://ifst.onlinelibrary.wiley.com/doi/full/10.1111/ijfs.13408) as 959 mg in 100 g. This means that about 9 grams of freeze-dried mangoes meet the daily vitamin C requirement of adults.

On the other hand, vitamin C level was determined as 225 mg/100g in another [study](https://www.sciencedirect.com/science/article/pii/S00236438140020848). Therefore, vitamin C of the final product is affected by various factors such as raw material type, maturity level and storage time before drying.

## How To Rehydrate Freeze Dried Mangoes

Freeze dried foods possess a remarkably high rehydration capacity; however, it's crucial to note that they won't fully revert to their original texture. After rehydration, they will become softer and more succulent.

The process of rehydrating freeze dried mangoes can be accomplished using water, fruit juice or milk. In one [study](https://www.sciencedirect.com/science/article/pii/S0023643809000383) freeze-dried mango slices (0.5 cm) were completely rehydrated in less than 20 minutes at 25ºC.

For the rehydration of freeze dried mangoes, simply place your desired quantity of freeze dried mangoes in a bowl and cover them with water. Allow them to soak for about 20 minutes until they absorb the water and plump up.

It's important to note that rehydrated freeze dried mangoes should be consumed within a few hours since they won't maintain the extended shelf life of the original freeze dried product. Store any unused portions in an airtight container in the refrigerator to preserve their freshness.

## Where To Buy Freeze Dried Mangoes

Freeze dried mangoes can be found in a variety of places both online and in physical stores such as Trader's Joe and Walmart. One of the most popular places to buy them is on Amazon, where you can find a wide range of brands and sizes to choose from.

Freeze Dried Mango: How to Make & Use


# How to Make and Use Freeze Dried Coffee

As the second most popular drink worldwide after water, more than 1.6 million cups of coffee consumed every day. Some people drink their flavorful coffee as a morning boost, while others can drink all day long.

Nowadays, coffee is not only a beverage but is a culture, a comfort, and a daily essential for countless individuals worldwide. While some people consider the sourcing, roasting, brewing and consumption of coffee as a whole, many others aim for convenience and quick consumption.

Imagine a process that transforms your favorite brew into a lightweight, shelf-stable, and easily transportable form without affecting its rich aroma and robust flavor. That's the magic of freeze dried coffee, a technique gaining popularity for its preservation prowess and convenience. In this article we will discover advantages, production and usage of freeze-dried coffee.

## Advantages of freeze dried coffee

Taste and flavor are very important when it comes to enjoying a cup of coffee. The loss of aroma and flavor substances that are formed during the roasting process and transferred to the water during the brewing process negatively affects the enjoyment of coffee. Therefore, a durable coffee product should have minimal impact on these components.

Freeze drying allows coffee to retain its natural flavors and aromas because it is carried out at low temperatures. Indeed, when you prepare a cup of coffee using freeze-dried granules, you can expect a rich and strong flavor that rivals freshly brewed coffee.

Spray drying, another method used in the production of soluble coffee. As a result of the heat, some of the aromatic substances unique to coffee are lost, and chemical changes can occur in the flavor substances. Therefore, there can be significant differences compared to freshly brewed coffee.

In addition to the flavor advantage, freeze-dried coffee also has an impressive shelf life. Unlike other types of coffee, which can become stale or lose their flavor over time, freeze-dried coffee can be stored for much longer without compromising on quality. So whether you are an occasional coffee drinker or a devoted coffee enthusiast, the long shelf life of freeze-dried coffee makes it a convenient and reliable choice.

## 1. Taste and flavor

For coffee lovers, taste and flavor are paramount. Industrially, 2 methods are widely used in the production of soluble coffee. Therefore, there are dozens of studies on how these methods affect the aromatic profile and sensory properties of coffee. The general conclusion of these studies is that freeze drying provides a much higher quality product than spray drying.

Indeed, the high temperatures applied in spray drying (typically higher than 300ºF) cause many aromatic compounds to volatilize and disappear. Moreover, these temperatures trigger some reactions in the product, such as the Maillard reaction. This results in a change in the sensory flavor.

However, freeze drying is carried out at gentle drying conditions and therefore has minimal impact on the aroma and flavor profile of the product. This allows for the preservation of delicate flavor profiles that may be lost through other processes.

Studies on coffee chemistry show that roasted coffee beans contain more than 800 volatile compounds. However, 117 of these compounds were [found](https://link.springer.com/article/10.1007/s11947-023-03067-4) in coffee brew. In one [study](https://www.researchgate.net/profile/Denisley-Bassoli-2/publication/266385918_Spray-drying_instant_coffee_product_at_low_temperature/links/551c25970cf2909047ba558a/Spray-drying-instant-coffee-product-at-low-temperature.pdf), it was observed that aromatic component retention varied between 60% and 80% depending on the concentration during spray drying at low temperatures.

In a 2015 [study](https://www.sciencedirect.com/science/article/abs/pii/S0260877414004312?via%3Dihub), the effects of spray drying and freeze drying processes on aroma in soluble coffee production were investigated. According to the results of this study, aroma retention was 57% in spray drying and 77% in freeze drying.

Another advantage of freeze-dried coffee is that it provides a consistent flavor across different batches. This consistency is highly valued by coffee lovers who appreciate the ritual of preparing and enjoying a cup of their favorite brew.

Overall, freeze-dried coffee offers a wide range of flavors to satisfy even the most discerning palates, from dark and earthy notes to subtle hints of fruit or chocolate.

### 2. Shelf-life

Products made durable by freeze-drying have an impressive shelf life. Due to the fact that chemical reactions are not triggered during the process, freeze-dried coffee can last for 3 to 5 years when stored under suitable conditions.

On the other hand, soluble coffee produced by spray drying has a shelf life of 1 to 2 years. These products are more exposed to aroma and flavor changes due to ongoing chemical reactions during storage.

### 3. Health benefits

Coffee offers a range of health benefits due to the bioactive components it contains. These effects are often due to the phenolic substances and antioxidants found in coffee. Some of these benefits [include](https://www.healthline.com/nutrition/top-evidence-based-health-benefits-of-coffee):

- May reduce the risk of type 2 diabetes
- May support brain health
- May promote weight control
- May be associated with reduced risk of depression
- Supports the liver and can protect it against diseases
- Supports heart health
- May increase longevity
- It may improve athletic performance.

The majority of studies observing these effects have been carried out directly with freshly brewed coffee. For soluble coffees to have the same effect, these valuable components must be preserved without damage during processing.

In one study, the phenolic content of coffees brewed with a percolator or coffee maker was 2-3 times higher than soluble coffees. However, the method by which instant coffee was obtained was not reported in this study.

According to the Pubmed database, some of the health benefits associated with freeze-dried coffee consumption are as follows:

- Anti-tumor effect against breast cancer cell [lines](https://pubmed.ncbi.nlm.nih.gov/34113419/)
- Positive [effect](https://pubmed.ncbi.nlm.nih.gov/35081143/) on certain gut bacteria and HDL
- Supporting weight [loss](https://pubmed.ncbi.nlm.nih.gov/21621391/) but also aggravating cholesterol

### 4. Preparation

The preparation of coffee drink using freeze-dried coffee does not require any special equipment such as pressure machines and percolators. By simply mixing the desired amount of granules into hot water, you can prepare your coffee easier and quicker. This makes it an ideal and economical choice for many people.

## How is freeze dried coffee made industrially?

Freeze dried coffee is made using a unique process that starts with perfectly roasted and ground coffee beans. The first step involves brewing a strong and concentrated coffee under pressure. This brew generally have low dry matter content. To decrease the cost, the brew is concentrated under vacuum upto 50 brix (soluble solid content). Then this concentrate is frozen to form ice crystals as a thin layer using a belt freezer. In the freezing step, low temperatures such as -40ºF was used to form small ice crystals. The thin ice layer is broken into small pieces using a mechanical grinder and spread onto trays.

<YoutubePlayer id="4G5LcVUcWAg" title="How is freeze dried coffee made industrially" />

The trays are loaded to freeze dryer and the process is started. Sublimation occurs under carefully controlled conditions of temperature and pressure. The result is coffee that retains its original flavor, aroma, and color, with almost all the moisture removed.

## How to make freeze dried coffee at home

Although it is widely available in the stores, of course you can transform your own favorite coffee into freeze-dried coffee and store it for several years.

- Step 1: Brew your coffee powder but make it much strong and concentrated than usual. The higher the concentration, the lower your production cost and the more product you get.
- Step 2: Cool down the brew (preferably quickly) and pour them to the freeze dryer trays evenly
- Step 3: Freeze the trays at least 4 hours.
- Optional step: Rapidly break the ice crystals into small pieces (Make sure that no melting occurs at this stage)
- Step 4: Run your freeze dryer to let it cold and ready
- Step 5: Load the trays and let it dry for at least 20 hours.
- Step 6: Check the coffee's dryness. If necessary, hold in freeze dryer for several additional hours.

## Freeze dried vs spray dried coffee

Freeze dried coffee and spray dried coffee are two common methods used to prodcuce instant coffee. While both methods remove moisture to create a convenient coffee product, there are some key differences between the two.

One significant difference lies in the process itself. Freeze drying involves freezing the brewed coffee and then slowly removing the water through sublimation. This method helps to preserve the aroma and flavor of the coffee while creating a granular texture.

On the other hand, spray drying involves spraying a fine mist of brewed coffee into a hot, dry chamber. The water quickly evaporates, leaving behind small coffee particles that dissolve easily in water. This process tends to produce a more powdery texture and may result in a different flavor profile.

Another difference is in the final product's shelf-life. Due to the freeze-drying process, freeze dried coffee generally has a longer shelf-life compared to spray dried coffee. This makes freeze dried coffee an ideal choice for those who want to stock up on their favorite coffee or for situations where freshness is important. However, spray dried coffee is still considered to have a decent shelf-life.

![Spray Dried vs Freeze Dried Coffee Appearance](/images/posts/spray-dried-vs-freeze-dried-coffee.webp)

It must be noted that, energy requirement for spray drying of coffee is lower than that of freeze drying. Therefore, spray dried instant coffees are cheaper than freeze dried ones.

## How to store freeze dried coffee

The best option for storing freeze dried products are air tight containers such as Mylar bags, mason jars or vacuum packagings. If you plan to store for an extended periods such as 3-5 years, it is logical to use oxygen absorbers and store in a dark place.

Best conditions for long term storage are lower than 75ºF and humidity under 40%.

How Long Will Freeze-Dried Coffee Last? Technically decades under ideal conditions. But, since it is an aromatic product, there is general aggrement on 3-5 years.
