Dehydrating is a method of food preservation in which moisture is removed from the food. Dehydrating inhibits growth of microorganisms and decay. Dehydrating can dramatically increase storage life for food.
Dehydrating causes minimal loss of nutrients, but if done properly that loss is quite small. You will retain about 90% of the vitamins and minerals. When using higher heats, foods will dehydrate faster, but this will result in more nutrient loss.
Always let foods cool for a few minutes. Check to see if the food is still moist or sticky. If it is leathery and pliable, it is usually done. However, foods that are overdried may become brittle and turn brown.
Always store dried foods in airtight containers. Store containers in a cool, dry place. Exposure to humidity, light and air during storage adversely affects storage life of dried foods.
We recommend a maximum storage time of one year for the best appearance and nutritional value. Vacuum packing greatly extends shelf life. Refrigeration or freezing will double or triple shelf life.
7. If I powdered my dried vegetables, what could I use them for?
Powdered onion and garlic, of course, are great seasonings for meats and sauces. Powdered tomatoes can be reconstituted into tomato sauce, paste, catsup, juice or soup. A blender or food processor will give you the finest texture. Store in air-tight container.
9. My apples and pears have darkened to a rusty-brown color while drying. Are they safe to eat?
Yes. Fruits that have turned brownish color are safe to eat. Many fruits will oxidize when the flesh of the fruit is exposed to air. By pretreating fruits, oxidation is reduced.
You can dry fruits, vegetables, meats, herbs, flowers, pet treats, etc. Dry left over bread for bread crumbs. You can dry almost anything that contains water.
12. Will flavors mix if I dry different foods together in the same dehydrator?
If you dry foods in the same category, such as fruits with other fruits and vegetables with other vegetables, the flavors should not mix. However, we do not recommend drying onions with any other foods.
16. The fruit sticks to the trays. How can I prevent this?
Fruits or thinly sliced vegetables may stick to your trays. You may want to purchase Clean-A-Screens to put on your trays to prevent these items from sticking.
