The fermentation environment temperature of "homemade enzyme" is more suitable for microbial reproduction. If the production is not successful, it is likely to produce some miscellaneous bacteria and harmful substances, which may easily cause food poisoning.

In addition, pectin may produce methanol after microbial fermentation. Homemade enzymes, others have no subsequent methanol removal process, which is also risky.

Extended data:

Enzymes, taking vegetables, fruits, etc. As a raw material, after adding sugar, sealing, preservation and other processes, full fermentation, and finally get a drinkable liquid. Zhu Yeshan, deputy director of the Department of Spleen and Stomach Diseases of Tangshan Traditional Chinese Medicine Hospital, said that some enzyme products contain probiotics and many microorganisms because they are products of fermentation. Under certain conditions, these probiotics and microorganisms can promote intestinal peristalsis.

So it can be said that the enzyme itself does not have the function of relaxing bowels and losing weight. Even if it is proved that enzyme products are effective in reducing weight, it is not enzymes that play a role, but probiotics, microorganisms and other product additives in fermented products.
