Dehydrating Fruits and Vegetables

Dehydrating Fruits and Vegetables:

Dehydrating is the oldest form of food preservation. In the beginning people used a lot of salt to preserve their food, and they dried their food in the sun or on top of the stove. Today we have food dehydrators to help in the process of drying. Dehydration is safe because if removes the water from the food, mold and bacteria cannot grow on it, and it will not spoil. Drying the food does cause a loss of some of vitamin A and C. It takes 6-16 hours to dehydrate vegetables, 12-18 hours to dehydrate fruits, and 6-20 hours to dehydrate meats. You can dehydrate fruits, vegetables and make beef jerky. Once you have dehydrated them I would seal them in the Mylar pouches/bags with the oxygen absorbers for long term storage.  Then place the Mylar pouches/bags  in the 5 gallon food grade buckets you can purchase with lids.

Different methods of dehydrating food:

1) Sun Drying--Difficult, need 3-4 hour sunny days of at least 100 degrees each day. This will only work in areas where you have this type of weather.
2) Oven Drying--Not very energy efficient, foods are not very tasty in the end, your oven must obtain a temperature below 200 degrees and you need to prop the oven door open to maintain air circulation during the drying time. To much trouble for me!
3) Electric Dehydrators--The best method for dehydrating your food. Now days they are energy efficient and can be operated at a low temperature. Look for electric dehydrated that have heat control and a fan to maintain the air circulation during the drying time. Watch for great sales. Check online too.

Does and Don't of Dehydrating your food (Follow the instructions in your Electric Dehydrator unit):

1) Do not keep the temperature too low or too high, follow the instructions.
2) Food should be dehydrated between 120 and 140 degrees Fahrenheit. Vegetables at 130 degrees, fruits at 135 degrees, meats are higher at 145-150 degrees.
3) The food should be leathery with no pockets of moisture when you touch it. Fruits, tear and check for moisture at the tear, if there is moisture, it is not dry enough. The vegetables should be tough, but can also be crisp. The meat should be tough, but shouldn't snap apart.
4) When storing your dehydrated food, make sure no moisture can get in. Best to seal in air tight contains, like the Mylar pouches/bags with oxygen absorbers as mentioned above. See the YouTube video on how to do this process yourself.
5) All vegetables except onions, peppers and mushrooms should be washed, sliced and blanched. Check online how long to blanch each type of vegetable you will be dehydrating.
6) All fruits should be washed, pitted and sliced. You can pretreat your fruits with lemon juice to prevent darkening while you are preparing for drying.
7) Dry the fruits and vegetables in single layers on trays.
8) Wipe of the fat of the jerky while it is drying.
9) Jerky does not store for long periods of time. If more than a month freeze or refrigerate. Or, you can seal the jerky in the Mylar pouches/bags, with the oxygen absorbers for longer storage.
