Advantages of Freeze Dried Products
1. Colour basically remains. As drying is operated in low temperature and vacuum condition, the physical and chemical property of food changed little. There is also possibility of oxidation and enzyme, thus easy to keep original color.
2. Fragrance basically remains. Because the fragrant components in food largely exist in amorphous concentrated section during freezing, the fragrance can be kept when ice crystals are gasified.
