Dragon fruit freeze dried uses the vacuum freeze-drying method of a freeze dryer to pre-freeze the moisture in the fruit, and then sublime the frozen moisture in the fruit under a vacuum environment to obtain freeze-dried fruit. In short, the water in the fruit is pumped in a low temperature environment to retain its original nutrition.
Dragon fruit freeze dried preserves the original color, fragrance, taste, nutrients and appearance of the original materials, and have good rehydration, and do not contain any additives. They are ideal natural hygienic food.
1. Freeze-drying is carried out at low temperature, so this kind of dog treat mix is especially suitable for many heat-sensitive materials.
2. When drying the at low temperature, the loss of some volatile components in the substance is small, and the original nutrients are maintained.
3. During the freeze-drying process, the growth of microorganisms and the action of enzymes cannot proceed, so the original shape can be maintained.
4. Because Dragon fruit freeze dried, as a kind of high quality pet food, is dried in a frozen state, the volume is almost unchanged, the original structure is maintained, and no concentration phenomenon occurs.
5. After drying, the material is loose and porous, and it is sponge-like. After adding water, it dissolves quickly and completely, and restores its original shape almost immediately.
6. Since the drying is carried out under vacuum, there is little oxygen, so some easily oxidized substances are protected.
7. Drying can remove more than 95-99% of moisture, so that the dried product can be stored for a long time without deterioration.
