When people enjoy it as a product with medicinal and edible properties, they usually eat "Nine-processed Polygonatum sibiricum". Instant Polygonatum sibiricum is usually packaged independently, which is convenient for consumption at any time. It can be eaten immediately after opening the bag, brewed into tea, boiled into soup, porridge, etc. to meet different needs. It is suitable for the busy pace of life, especially for the relevant sub-healthy people, and has the effects of replenishing qi and nourishing yin, strengthening the spleen, moistening the lungs, and benefiting the kidneys.

[0003] However, the traditional production of instant Polygonatum has the following disadvantages:
