If the fruit enzyme fermentation time is too short, it will produce a certain concentration of nitrite, and if the fruit and vegetable raw materials with higher nitrogen content are added to the raw materials, the nitrite content will be higher. Nitrite is a known carcinogen, and long-term consumption can easily lead to esophageal cancer and gastric cancer.

Mold pollution: mold, including many kinds of Penicillium and Aspergillus, will produce a substance called patulin. However, this kind of mycin has shown neurotoxicity, embryotoxicity and carcinogenicity in animal experiments, and it will inhibit the immune system of animals.

Although the harm to human body has not been clearly concluded, an adult weighing 70 kg should not consume more than 28 micrograms of patulin every day. The content of patulin in fruit products contaminated by mold is as high as 1 microgram per gram.

Extended data:

The essence of fruit enzyme is no different from sauerkraut juice or fermented wine. "Enzyme" is not a new thing, but a petty bourgeoisie translation of the standardized Chinese term "enzyme". Enzymes are indispensable catalysts in life activities. Speaking of weight loss often mentioned in enzyme propaganda, there are indeed some enzymes responsible for "burning" the fat in cells.

However, fat burning is a series of complex reactions. Only under certain circumstances can this enzyme "burn fat" and combine with fat molecules, and then further reaction will take place, and finally fat will be converted into carbon dioxide and water. However, when the enzyme is denatured, it is impossible to burn fat. The factors leading to enzyme denaturation are temperature, acidity, salt concentration and so on.

For the enzymes eaten in the stomach, even if they have the function of burning fat, the activity of the enzymes originally needed for burning fat in a neutral environment will be greatly reduced due to the influence of gastric acid, and even cut into pieces by protease in digestive juice. After being cut into pieces, these enzymes are no longer active, let alone burning fat.
