Freeze-drying, also known as lyophilization, is a sophisticated preservation process that maintains the nutritional integrity of fresh fruit better than any other drying method.

## Understanding the Freeze-Drying Process

The process involves three main stages:

- **Freezing:** Fruit is rapidly frozen at extremely low temperatures (-40°F to -50°F)
- **Primary Drying:** Ice sublimates directly from solid to gas under vacuum
- **Secondary Drying:** Remaining moisture is removed through controlled heating

## Why Nutrients Are Preserved

### Low Temperature Protection

Heat-sensitive vitamins like vitamin C and B-complex vitamins are preserved because the process operates at low temperatures. Traditional drying methods use heat that destroys these delicate compounds.

### Oxygen Exclusion

The vacuum environment removes oxygen, preventing oxidation that degrades antioxidants and vitamins. This is why [freeze-dried fruit](https://fdtastyfood.com/ko/products/) maintains its bright color and nutritional value.

## Nutrient Retention Comparison

| Method | Vitamin C | Vitamin A | Antioxidants |
| --- | --- | --- | --- |
| Freeze-Drying | 97% | 95% | 98% |
| Air Drying | 60% | 50% | 55% |
| Sun Drying | 45% | 40% | 35% |
| Dehydration | 70% | 65% | 68% |

## The 97% Claim Explained

Studies show that freeze-dried fruit retains between 95-99% of its original nutrients, with an average of 97%. This makes it nutritionally equivalent to fresh fruit on a per-serving basis when water content is accounted for.
