Removing and Storing Dehydrated Food

Information on Food Drying

Working Procedure

Vegetables and fruits selected for drying should be of the best quality, i.e., fresh and ripe. Dried or inferior products are not suitable if you want to achieve good quality products. If you use unripe fruits and vegetables, your resulting products will be colorless. Conversely, overripe fruits and vegetables will result in products that are too soft and mushy.

Products prepared for drying are best if dried as quickly as possible after harvest. First, wash the fruits and vegetables thoroughly. Remove any bruised or spoiled parts.

For maximum satisfaction and energy savings, you can peel some types of fruits and vegetables beforehand and then cut them into smaller pieces. They will dry faster.

Preparation

Enzymes in fruits and vegetables are responsible for changes in color and taste during ripening. These changes also occur during drying and storage.

The preheating method can be used as a pre-treatment for vegetables. This helps preserve the original color of the vegetables and speeds up drying. This method also ensures the preservation of the original taste during storage and easier preparation before cooking, as well as cooking time.

Most light-colored fruits (e.g., apples, apricots, peaches, and pears) tend to darken during drying. To prevent this undesirable effect, you can soak such fruits in a suitable solution before drying.

Soaking Food

Fruits can be soaked in the following solutions:

You can pre-steam fruits. However, pre-steamed fruits may soften, making them more difficult to process and heavier to handle.

Syrup can help preserve the color of apples, apricots, figs, nectarines, peaches, pears, and plums.

Fruits with thick skins (grapes, dried plums, small dark plums, cherries, figs, and berries) can be heated in water, which helps to crack the skin. This will allow moisture to dry out of the fruit more quickly.

Remove excess water from the prepared fruits and vegetables by first placing the slices on paper towels or clean cloths. The drying racks should be filled with a thin layer of slices. If necessary, you can use thin gauze to prevent the slices from sticking together.

The amount of fruit and vegetables to be dried at one time should not exceed 2/3 of the surface of each drying rack and a height of 2.5 cm.

Rehydrating Food

All dehydrated fruits can be rehydrated. However, most fruits are more popular in dried form. Vegetables, on the other hand, are more popular in rehydrated form.

For rehydrating vegetables for cooking, wash them in water, then soak them in unsalted cold water so that they are completely covered. Leave them to soak for 2 to 8 hours, and then cook them in the same water in which you soaked the vegetables. If more water is needed, add it. Bring the water to a boil, then reduce the temperature and continue cooking. You can also add salt to taste, but only at the end of cooking, as salt slows down the rehydration process. Compared to fresh products, cooking reduces flavor and texture.

For rehydrating vegetables such as carrots, you need ice-cold water, and the vegetables should be kept in the refrigerator.

Dried food can be rehydrated by soaking, cooking, or a combination of both. Dried food is unique, so you should not expect the same product as fresh food.

Drying does not eliminate bacteria and yeasts from food. However, if fruits and vegetables are soaked at room temperature, bacteria and yeasts can multiply. Soaking fruits and vegetables in cool conditions is safer.

Dried and rehydrated fruits and vegetables can be used in many ways. Dried fruits can be served as tasty snacks at home, on outings, or during sports. Chopped into small pieces, they are excellent for cakes and cooking.

Drying

The drying time varies depending on the type of fruit and vegetable, the size of the pieces, and the fullness of the drying rack. To check if the fruit and vegetables are sufficiently dry, remove a few pieces from the dryer and let them cool. When they are warm, they contain more moisture than when they have cooled down.

Dried vegetables should be hard and brittle. Dried fruits should be leathery and flexible. If you want to store them for a longer period, homemade dried fruit should be drier than commercially sold fruit.

Packaging and Storage

Fruits cut into various sizes should be left to stand for one week after drying. This will equalize the moisture between the individual pieces. The fruit can then be stored in non-plastic and non-metallic containers, which should be stored in a dry place.

Before packaging in containers, fruits and vegetables should be properly cooled. Storage in small containers is best, as it allows for quick consumption after opening.

When packaging, be careful not to turn the pieces too much, as they may crumble. Glass bottles and jars intended for freezing are suitable containers for storage. Metal containers are suitable only if the food is first packed in a plastic bag.

Dried fruits should be checked once a month. If you notice that moisture has entered the container, open it immediately and consume the contents.

Rotating Racks

The fruit dryer you purchased is designed for natural airflow to remove moisture from food. To ensure even drying, the position of individual racks should be changed during drying. Racks located at the bottom of the appliance are exposed to higher heat. Simple rotation of the racks ensures even drying.

Recipes

Mixed Fruit Pouch

Cut the fruit into uniform pieces. After drying and cooling, add a quarter cup of nuts.

Apple-Cinnamon Rings

Peel and core the apples and cut them into rings. Sprinkle with cinnamon and dry.

Jerky

Place thin slices of beef or turkey meat in a glass container and pour over 1/2 cup soy sauce, 2 tablespoons brown sugar. Mix well, ensuring all meat pieces are covered. Cover with a plastic bag and let stand for 10-15 minutes. Then place the meat slices on the racks and dry for 8-10 hours.

Yogurt and Yogurt Dishes

Yogurt Production

  1. Pour 4 glasses of milk into a pot. You can use any milk: whole, semi-skimmed, or powdered.
  2. Heat and remove from the stove before it boils.
  3. Stir in 2 tablespoons of plain yogurt.
  4. Pour into yogurt cups and cover with lids. Butter cups can also be used as a suitable substitute.
  5. Place on the top rack and leave for 6 hours. Do not use the top cover.
  6. Store in the refrigerator before consumption.

*The yogurt used should be free of chemical additives.

If you prefer your yogurt sweeter, you can sweeten it with honey.

Frozen Fruit Yogurt

Peel, wash, and blend all fruits. Mix the remaining ingredients in a bowl, adding the blended fruit.

Freeze everything in a plastic container with a lid. Place in the freezer. Once the yogurt is frozen, remove the lid from the container.

Herbs and Spices

With the food dehydrator, you can create the aroma of your favorite herbs and spices and enjoy it anytime. Simply use plants you have grown in your garden. Simply break or cut them into small pieces, place them on the rack, and dry them. Drying time should be approximately 5 hours. They can be stored in decorative containers or cloth bags tied with ribbon. You can sprinkle them with rosemary or mint before drying. The best storage method is to keep the containers closed.
