Why KOYAH Uses Freeze-Drying: The Superior Method for Nutrient Preservation
Share
At KOYAH, our mission is to help you Eat More Fruits and Vegetables — and to do that, we focus on offering the least processed supplements on earth. One of the key ways we make that possible is by choosing the freeze-drying process over other common drying methods. But why is freeze-drying so much better? Let’s break it down.
What Is Freeze-Drying?
Freeze-drying, also known as lyophilization, is a gentle drying process that removes moisture from food by freezing it and then reducing the surrounding pressure to allow the frozen water to sublimate directly from ice to vapor. This happens at low temperatures and without using high heat, which is where freeze-drying stands apart from other methods.
How Freeze-Drying Compares to Other Drying Methods
| Drying Method | Temperature Used | Nutrient Retention | Flavor/Color Preservation | Shelf Life |
|---|---|---|---|---|
| Freeze-Drying | Low (below freezing, vacuum) | Excellent (highest retention of vitamins, enzymes, and antioxidants) | Best (natural color, flavor, and texture remain intact) | Long (up to 25 years) |
| Spray Drying | High heat (150-300°F) | Moderate to poor (heat-sensitive nutrients like Vitamin C are often lost) | Fair to poor (can affect flavor and color) | Moderate |
| Air Drying / Dehydrating | Warm air (95-160°F) | Moderate (nutrient losses vary by temperature and time) | Color may darken, flavor can change | Moderate |
| Drum Drying | High heat (200-300°F) | Poor (significant nutrient loss due to heat exposure) | Often results in cooked flavor and altered color | Short to moderate |
Why Freeze-Drying Matters for Your Health
- Maximizes Nutrient Retention: Freeze-drying preserves delicate vitamins like Vitamin C, B vitamins, and antioxidants that are easily destroyed by heat-based drying methods.
- Maintains Whole Food Integrity: Because there’s no high heat, freeze-dried powders keep their natural color, flavor, aroma, and texture, making your smoothies, recipes, and capsules taste and feel closer to real, fresh produce.
- No Need for Additives or Preservatives: The low-moisture environment prevents spoilage without relying on chemicals, fillers, or additives.
- Long Shelf Life Without Compromise: Properly stored freeze-dried powders can last years without losing quality, making them a reliable option for daily use or long-term storage.
