1. Thaw vegetables slightly before placing them on dehydrator trays.
2. Spread in a single layer for even drying.
3. Dehydrate according to individual vegetable guidelines.
4. Check for doneness after 6 hours.

Using Frozen Veggies? Got Clumps?

💡 Tip: Before opening the bag, gently shake it on the counter to break up frozen clumps. If needed, let the bag sit in the sink for 30 minutes to soften slightly.

How to Blanch Vegetables Before Dehydrating

Some vegetables require blanching to retain color, texture, and nutrients.

Vegetables That Need Blanching Before Dehydrating:
🥦 Broccoli, 🥕 Carrots, 🥬 Kale, 🌶️ Peppers, 🥔 Potatoes

Blanching Steps:

1. Bring a pot of water to boil.

Using Lemon Juice (or Ascorbic Acid)

Certain vegetables, like carrots, apples, and potatoes, need a quick lemon juice spray before dehydrating to prevent browning (oxidation).

Lemon juice also helps prevent bacterial growth during drying.

How to Tell When Vegetables Are Fully Dehydrated
