About yeast plums: Enzymes contain catabolic enzymes and cannot be stored with plums. Plums contain water and protein. If yeast powder or liquid enzyme is used with plums, catabolic enzymes in the enzymes will decompose the protein of plums. Then plums will be unrecognizable and the enzyme will lose its activity. It is also possible to breed new flora without sealing, so the enzyme can't be stored with the plum, and the plum can't have an enzyme component, because the enzyme is very active. Enzymes need strong sealed fermentation, which can destroy many other bacteria and ensure the stability of enzyme flora. When they are with plums, they will continue to ferment. How many harmful bacteria do plums produce when exposed to the air? It can only be said that plums contain enzymes, but they need to be extracted. Without fermentation and extraction, it is ordinary fruit. [naughty]
