Freeze-dried powder is a pure natural food to improve immunity. It is suitable for people with poor resistance and frequent illness from children to the elderly. It can improve immunity, strengthen physique, reduce diseases and speed up recovery.

A body with low immunity is prone to infection or cancer. Abnormal immunity can also produce harmful results to the body, such as allergic reactions and autoimmune diseases. For various reasons, the immune system can't play its protective role normally. In this case, it is easy to cause infections such as bacteria, viruses and fungi.

Extended data:

Freeze-drying refers to pre-cooling and freezing a substance containing a lot of water into a solid, and then directly subliming the solid water under vacuum, while the substance itself remains in the frozen ice shelf, so its volume remains unchanged after drying. The solid water absorbs heat in the sublimation process, which leads to the temperature drop of the product and slows down the sublimation speed. In order to improve the sublimation speed and shorten the drying time, it is necessary to heat the product properly. The whole drying process is carried out at a lower temperature.
