Problems solved by technology

Because the wolfberry fruit contains about 30% wolfberry seeds, the wood fiber in the wolfberry seed shell is not easy to be crushed when pulverized, causing the wolfberry fruit powder to stay in the pulverizer for too long, on the one hand the nutrition of the wolfberry is lost in large quantities, and on the other On the one hand, wolfberry fruit powder is easy to saccharify and block the unit. Again, 30-40% of the seeds and skins in the finished product have poor sensory perception and precipitation after dissolving in water, which seriously affects the sales and price of the final product.
[0014] In addition, due to the high sugar content of wolfberry powder, it is easy to absorb moisture and agglomerate during storage, thereby reducing the commercial value of freeze-dried wolfberry powder
