Dehydrating is a method of preserving fruits, vegetables, and herbs by removing their moisture content, extending their shelf life while maintaining nutritional value and flavor. This chapter introduces the basics of dehydrating and its benefits for homemade culinary creations.
Getting Started
Before diving into dehydrating, gather essential equipment and familiarize yourself with different methods of drying foods.
Equipment Checklist:
Dehydrator: Choose a food dehydrator suitable for home use, with adjustable temperature settings and multiple drying trays.
Baking Sheets and Parchment Paper: For oven drying, if not using a dehydrator.
Sharp Knife and Cutting Board: For preparing fruits, vegetables, and herbs before drying.
Kitchen Towels: For patting dry fruits and vegetables before placing them in the dehydrator.
Air-Tight Containers or Mason Jars: For storing dried foods once they're ready.
Optional Supplies:
Citric Acid or Lemon Juice: Helps preserve color in fruits during drying.
Herb Grinder: For grinding dried herbs into powder.
Food safe desiccant packs: To keep dehydrated foods from absorbing moisture in the air.
Selecting Ingredients:
Fruits: Choose ripe, firm fruits such as apples, bananas, berries, and mangoes.
Vegetables: Select fresh vegetables like tomatoes, bell peppers, carrots, and zucchini.
Herbs: Harvest fresh herbs such as basil, oregano, thyme, and mint.
Workspace Setup:
Sanitization: Clean and sanitize dehydrator trays, knives, and cutting boards before use.
Organizational Tips: Arrange ingredients and tools for efficiency during the drying process. Take extra care to avoid cross contamination when preparing foods.
Using a Food Dehydrator:
Prepare Ingredients: Wash, peel, and slice fruits, vegetables, or herbs evenly. Most fruits and vegetables will dry most evenly when slices to ¼ inch or less in thickness.
Arrange on Trays: Lay out pieces on dehydrator trays in a single layer, ensuring airflow between pieces.
Set Temperature: Adjust the dehydrator temperature based on the type of food being dried (e.g., 125°F for fruits, 135°F for vegetables, and herbs).
Monitor and Rotate: Check progress periodically and rotate trays for even drying.
Cool and Store: Once dried to crispness, cool completely before storing in airtight containers.
Oven Drying:
Prepare Ingredients: Prepare fruits, vegetables, or herbs as for dehydrator drying.
Preheat Oven: Set oven to the lowest temperature (usually around 140°F).
Arrange on Baking Sheets: Place pieces on parchment-lined baking sheets in a single layer.
Monitor and Rotate: Check and rotate trays every hour for even drying.
Cool and Store: Cool completely and store in airtight containers once dried.
Storing Dehydrated Foods:
Cool, Dark Place: Store dried foods in a cool, dry place away from direct sunlight to preserve color and flavor.
Airtight Containers: Use airtight containers or vacuum-sealed bags to prevent moisture absorption and extend shelf life.
Labeling: Label containers with the contents and date of drying to track freshness and ensure rotation.
Shelf Life: Most dehydrated foods can be stored for several months to a year if properly dried and stored. Here’s a guide to the shelf life of commonly dried garden foods.
Commonly Dried Garden Foods and Their Shelf Life:
Fruits:
Apples: Up to 1 year
Bananas: Up to 1 year
Berries (strawberries, blueberries): Up to 1 year
Peaches: Up to 1 year
Plums: Up to 1 year
Vegetables:
Tomatoes (sliced or cherry tomatoes): Up to 1 year
Bell Peppers (sliced): Up to 1 year
Carrots (sliced or shredded): Up to 1 year
Zucchini (sliced or shredded): Up to 1 year
Green Beans: Up to 1 year
Herbs:
Basil: Up to 2 years
Oregano: Up to 2 years
Thyme: Up to 2 years
Mint: Up to 2 years
Parsley: Up to 2 years
Note: Shelf life can vary depending on factors such as drying method, storage conditions, and moisture content. Properly dried foods should be crisp and brittle with no signs of moisture when broken.
