" Enzyme " is a popular hot word on the Internet recently. Many products are promoted to detoxify, nourish the skin, slim down, improve immunity, and even prevent cardiovascular and cerebrovascular diseases , tumors and various difficult and complicated diseases. They are almost omnipotent and are called "oral golden liquid". Although it is expensive, people still flock to it for their health.
So, what exactly is enzymes really that magical?
Is enzyme the same thing?
The term "enzyme" comes from Japan, that is, enzyme . enzyme is protein synthesized by living cells and has a high-efficiency catalytic effect on specific substrates. It is the main catalyst for catalyzing various metabolic reactions in the body. There are many types of enzymes in our body, such as digestible pepsin , trypsin , etc., which play a role everywhere in the body.
Currently, enzymes as food or health food on the market are essentially different from enzymes. According to the "Pocket Book of Health Foods" compiled by Shinichi Yamauchi, enzymes have the meaning of "extract of plant enzymes" or "the essence of plant enzymes extracted". They are fermented foods made from wheat, rice germ and soybeans as raw materials and fermented with lactic acid bacteria or yeast . Traditional fermented foods in my country, such as bean paste, noodle sauce, fermented bean curd, kimchi, wine-making , rice vinegar, etc., are also enzyme foods.
enzyme health care function thanks to its active ingredients such as flavonoids , phytochrome , organic acids and superoxide dismutase (SOD), probiotics such as lactic acid bacteria and yeast, as well as various amino acid , vitamins and mineral elements. These beneficial ingredients give enzymes certain antioxidant, removing free radicals of , improving gastrointestinal function, regulating intestinal bacterial flora , and laxative care.
2016, China Biofermentation Industry Association as a standardized enzyme product, formulated the "Enzyme Product Classification Guidelines". Edible enzymes refer to enzyme products that are made with animals, plants, edible fungi, etc. as raw materials, with or without auxiliary materials added and without adding auxiliary materials, and containing specific biologically active ingredients and can be eaten by humans, including fruit enzyme , brown rice enzyme, mushroom enzyme, probiotic enzyme, etc.

Health knowledge "key points"
China has clear registration and production and operation regulations for health care products. Health foods are foods that claim to have specific health care functions or for the purpose of supplementing vitamins and minerals. As a health care product, it must have the following four characteristics:
1. It must be food;
2. It is not a drug, and the main purpose is to regulate the function of the body;
3. It has specific health care functions;
4. It has specific applicable groups.
The above four characteristics are the principles that everyone needs to grasp when choosing health care products.
Homemade fruit and vegetable enzymes safe?
With the rapid development of enzyme foods, some homemade enzyme foods have also become popular, and the most common ones are fruit and vegetable enzymes.
Usually, commercial enzyme products have strict requirements on the fermentation matrix, strain, temperature, humidity and process. The method of making homemade fruit and vegetable enzymes is much simpler. Generally, a variety of fruits and vegetables are used, plus sugar or honey, and let them ferment naturally in a closed bucket or kimchi jar.
In this process, if the fruits, vegetables, etc. used for fermentation are of poor quality, improper cleaning or incomplete disinfection of the container, it is inevitable that there may be harmful bacteria contamination.During the fermentation process, mycotoxin may also be produced such as penicillin and ochratoxin. Eating fruit and vegetable enzymes containing these harmful ingredients can easily cause liver and kidney damage and endanger health.
In addition, the fermentation process of is greatly affected by the external environment, such as temperature and humidity. Once , this process is uncontrollable, harmful substances such as methanol will be produced during the fermentation process.
Some scholars have tested the content of nitrite in homemade fruit and vegetable enzymes, and its content is 100 to 400 times the maximum allowable amount in Chinese food safety standards.
Can fruit enzymes lose weight?
There is a saying that "fruit enzymes contain lipolytic enzymes, which can decompose human body fat, can make people lose weight and maintain their figure." Is this true?
The raw materials of fruit enzymes mainly include various fruits and sugars, which are naturally fermented under sealing conditions. The product contains sugar, lactic acid, alcohol, amino acids, vitamins, minerals, and a certain number of lactic acid bacteria or yeasts, protease , and lipase .
At first glance, there is lipase, which is indeed consistent with the promotion of the product! Lipase is a type of enzyme that hydrolyzes oils and fats. Its targets natural oils and fats, and its site of action is the ester bonds connected to fats in oils and fats. In theory, lipase can indeed hydrolyze fats. However, since lipase is an enzyme, it is composed of proteins. Lipase is eaten into our mouths and into the stomach. Under the action of gastric acid and pepsin, the proteins that make up lipase will denature, decompose, and then lose their activity. has no activity, so how can we talk about decomposing fat?
Why do people still say that they really lose weight after taking enzymes? Some weight loss products under the banner of "fruit enzymes" have been found to be illegally added to sibutramine hydrochloride, etc., which is a central nervous system inhibitor, which was used for the treatment of obesity and has now been stopped in most countries around the world. After reading these, I believe you will have some insights into the "weight loss myth" of fruit enzymes.
