Quick Answer
To ensure successful food drying, it's essential to properly prepare the food before placing it in the solar dehydrator. This involves cutting, washing, and sometimes blanching the food to remove excess moisture and preserve nutrients. The specific food prep process varies depending on the type of food being dried.
Pre-Treatment Techniques
Before placing food in the solar dehydrator, it’s often necessary to pre-treat it to remove excess moisture and prevent spoilage. For fruits and vegetables, blanching in boiling water for 2-3 minutes can help inactivate enzymes that break down cell walls and cause spoilage. For leafy greens, a quick dip in cold water or a spin dry can be sufficient to remove excess moisture.
Cutting and Sorting
Cut food items into uniform pieces to ensure even drying and prevent over-drying in certain areas. For example, slice apples into 1/4-inch thick rounds, and sort out any soft or damaged pieces that may not dry properly. For leafy greens, remove thick stems and tear the leaves into smaller pieces.
Washing and Sanitizing
Wash all food items before dehydrating to remove dirt, bacteria, and other contaminants. Use a gentle soap and cold water, and rinse thoroughly to prevent any residue from affecting the drying process. For added safety, sanitize the food with a 1:10 solution of white vinegar and water, or a sanitizer specifically designed for food preparation.
