Among the best snack foods are freeze-dried strawberries. To prevent food from spoiling and reduce weight, water is extracted during freeze-drying. If you have a conventional oven or freeze-dryer, you can do this at home. When the berries have dried, consider eating them as soon as possible, incorporating them into meals, or storing them in a vacuum sealer.
How To Make Freeze-Dried Strawberries
Wash your berries, then slice them thin. Place the berries into a Ziploc bag and squeeze out the air. In a cooler, add dry ice and sit the bags of fruit on top. Close the lid but allow for a small opening so air can escape. Once the dry ice has melted, the berries should be dry.
What Is Freeze Drying Foods
Freeze drying dates back hundreds of years as a method of preserving fruit. By using the sun to dry food, freeze-drying can be accomplished. There are now so many other ways you can freeze dry foods. In regions where the weather is very cold, and altitudes are high, the fruit can dry very quickly as a result of this tradition.
It has been practiced for a very long time in East Asia, South America, and Northern Europe. Food brands have now embraced freeze-drying techniques to preserve meals without the loss of nutrients.
With the freeze-drying technique, fruits and vegetables are completely dry, unlike dehydration, which only removes a third of moisture, allowing molds and bacteria to grow. The foods that have been freeze dried, however, can be regenerated into their original form after you add water. Freeze-drying takes out the water completely from foods, so they do not need to be preserved. Foods can be stored for many years when packaged and stored properly.
Vacuum Sealing Dried Fruits
1. Under low heat, place the sliced fruit into a vacuum chamber. Let the sublimation process take place.
2. Check to see if all the moisture from the fruit has evaporated after the water crystals have dried.
3. To retain its original color, shape, and taste, you will need to add a little water to your fruit when you are ready to use it.
Using Your Freezer
1. Lay all the fruit out side by side on your baking sheet.
2. Put your tray in the freezer flat.
3. Let the fruit thaw at room temperature after it has frozen in the deep freezer.
4. The fruit will turn black once it is thawed if it is not dried properly. If you have freeze-dried the berries properly, they will retain full color, so test individually to be sure.
5. After the drying process is complete, simply seal the fruit in a ziplock container and store it.
Dry Ice Technique
When the air is dry, you should apply this technique. In the event of rain, the drying process could be slowed down.
You will need the following:
You may choose any fruit you like
Gloves with insulation
Containers large enough to be used as coolers
Enough dry ice to completely cover the food
1. Make sure the dry ice completely covers your food. The amount of ice you use for drying fruit should match the amount of fruit.
2. It is best to leave the lid open, so any pressure that builds-up will be relieved as the dry ice melts.
3. When all the ice is completely melted, remove the fruit, which should be fully dried, then store it in an air-tight container.
Benefits Of Freeze Drying
Food that has been freeze-dried and lost its moisture can be used as toppings for many different types of foods. The flavor and nutritional integrity of freeze-dried food can also be maintained when it is kept at room temperature for lengthy periods of time, in spite of the freezing temperatures used to preserve it.
Keeping freeze-dried foods fresh requires no additions, which is another advantage. Freeze-drying maintains the nutrition of the food as only moisture is removed. In addition to only using moisture and not cooking the fruit, freeze-dried fruit maintains a beautiful taste. The shelf life of canned and jarred food is shorter than that of freeze-dried food, which can be frozen for years to come.
Storing Freeze Dried Berries
Strawberries can last sealed up for years if you don’t expose them to air. In the presence of too much oxygen, strawberries can rot or get chewy.
The bag should contain an oxygen absorber, which will make sure it stays fresh as long as possible. The small oxygen absorbers are transparent packs that reduce the oxygen in a package or remove it completely. Oxygen absorbers are affordable and work well to add that extra layer of freshness and protection to your berries.
Freeze drying foods is versatile, cost-effective, and healthy all at the same time. You can freeze-dry berries a few different ways, which allows you to choose the way you like best.
