Drying removes moisture from food, preventing bacterial growth and preserving nutrients. Dried foods are lightweight, compact, and shelf-stable for 6-12 months or more.
Drying Methods
Electric Dehydrator
Most reliable method. Consistent temperature, good airflow, weather-independent.
- Temperature: 95-155°F depending on food
- Time: 4-12 hours depending on food and thickness
- Best for: Fruits, vegetables, herbs, jerky, yogurt
Solar Drying
Traditional method using sun and airflow. Requires hot, dry weather with good ventilation.
- Temperature: Ambient (needs 85°F+ days)
- Time: 2-4 days
- Best for: Herbs, some fruits, tomatoes
- Not recommended for: Vegetables (need higher temps for safety)
Oven Drying
Can work if oven goes to 140°F or lower. Prop door open for airflow.
- Temperature: Lowest setting (ideally 140-150°F)
- Time: 6-12 hours
- Best for: Small batches when dehydrator is full
Air Drying (Herbs)
Hanging bundles in warm, dry, dark space with good airflow.
- Time: 1-3 weeks
- Best for: Herbs, flowers, some seeds
Preparing Food for Drying
Fruits
- Wash and slice uniformly (1/4 inch thick)
- Treat with ascorbic acid or lemon juice to prevent browning
- Dry at 135°F until leathery with no moisture pockets
Vegetables
- Wash and slice uniformly
- Blanch before drying (stops enzyme action)
- Dry at 125-135°F until brittle
Herbs
- Harvest just before flowering for peak flavor
- Rinse gently and pat dry
- Dry at 95-105°F or air dry in bundles
- Store whole, crush when using
Drying Times
| Food | Preparation | Temperature | Time |
|---|---|---|---|
| Apples | 1/4 inch slices | 135°F | 6-10 hours |
| Bananas | 1/4 inch slices | 135°F | 8-12 hours |
| Tomatoes | Halved or sliced | 135°F | 8-12 hours |
| Carrots | 1/8 inch slices, blanched | 125°F | 6-10 hours |
| Green Beans | Blanched, cut | 125°F | 6-10 hours |
| Herbs (basil) | Whole leaves | 95°F | 2-4 hours |
| Herbs (rosemary) | Sprigs | 95°F | 2-4 hours |
| Jerky | 1/4 inch strips | 155°F | 4-8 hours |
Testing for Dryness
- Fruits: Leathery, pliable, no moisture when torn
- Vegetables: Brittle, snap when bent
- Herbs: Crumble easily between fingers
- Jerky: Leathery, bends without breaking, no moisture inside
Storage
Store dried foods in airtight containers (glass jars, Mylar bags with oxygen absorbers) in a cool, dark, dry place.
- Condition dried fruits: Place in sealed container for 7-10 days, shake daily to distribute moisture
- Check for moisture: Condensation on jar = not dry enough, return to dehydrator
- Label: Contents and date
- Shelf life: 6-12 months at room temperature, longer in freezer
Using Dried Foods
- Rehydrate: Soak in water 1-2 hours before using
- Cook directly: Add to soups, stews (they will rehydrate during cooking)
- Snack: Dried fruits and jerky ready to eat
- Herbs: Crush into dishes while cooking
