(Compared to the usual drying methods such as drying, drying, boiling, spray drying and vacuum drying)
1. It dries at low temperatures, does not denature proteins, and causes loss of biological activity such as microorganisms.
2, due to low temperature drying, there is almost no loss of volatile components and heat-denatured nutrients and aromatic components in the material.
3. During the low temperature drying process, the growth of microorganisms and the action of enzymes are almost impossible, and the original properties of the substances can be best maintained.
4, the volume after drying, the shape is basically unchanged, and the rehydration effect is good.
5. Because it is usually dried under vacuum, oxygen is very rare, protecting the easily oxidizable material.
6, can remove 95-99.5% of the water in the material, so that the product has a longer shelf life.
