PREPARATION & PRETREATMENT OF VEGETABLES:
Vegetables dried at home require a little more effort in processing and storage than
do fruits because they are low in acid and have little sugar. Some vegetables have a
poor quality when dehydrated, and are better frozen than dried. Others, such as
potatoes, are available at reasonable prices all year round, and it may not be worth
your time to dry them unless they are used for lightweight camping. Be selective in
the vegetables you choose to dry.
Preparation:
Select only the highest quality, fresh, crisp and tender vegetables for drying. Wash
vegetables carefully just before processing to remove dirt and bacteria. Most
vegetables should be peeled, trimmed, cut, or shredded prior to drying.
Pretreatment:
Blanching vegetables prior to drying destroys the enzymes that produce off flavors
during storage, resulting in poor texture and poor re-hydration. Steam blanching is
preferred over water blanching because there is less flavor and vitamin loss.
Microwave blanching is also excellent and usually keeps a brighter color in the
vegetables.
Steam Blanching:
Layer prepared vegetables in the top portion of a steamer, no more than 2 to 2 ½
inches deep. Steam until vegetables are heated all the way through but are not
cooked enough to eat (usually 2 to 3 minutes). Small pieces may need occasional
stirring to steam blanch evenly. Transfer steamed vegetables directly to drying trays,
working as quickly as possible.
Microwave Blanching:
Microwave ovens are convenient for blanching fresh vegetables. Prepare vegetables
as for steam blanching. Place vegetables with small amount of water (refer to your
microwave oven cooking chart) in a covered casserole dish. Cook for only ¼ to ?the
time specified in the chart, stirring well after half of the blanching time. Microwave
blanched vegetables will be more brightly colored than those that are steam blanched.
Transfer blanched vegetables directly to drying trays, working as quickly as possible.
