Seed enzyme is legal. After investigation, "One Seed" is a registered trademark applied by Linyi Gengnongge Trading Co., Ltd., and the drug or health food named "Fruit and Vegetable Enzyme" is not registered (filed). Enzyme, the word comes from Japan, which is often called "enzyme". Before liberation, enzyme was also called "enzyme" in China textbooks, and it is still called "enzyme" in Taiwan Province Province. But the popular health food on the market is called "enzyme", not "enzyme" of enzyme. According to the Japanese scholar Shinichi Yamauchi's Health Food Pocket Book, the original name of "enzyme" in Japan is "plant enzyme", which is translated into "plant enzyme extract" or "plant enzyme" in Chinese. The research on enzyme preparation in China is still in the primary stage, and the market development has just started. Due to the lack of targeted supervision and control, the corresponding process technology, quality evaluation standards and management regulations are not perfect, resulting in monotonous enzyme varieties and poor quality in the domestic market, and few products have obtained QS certification or health care approval. At present, it is urgent to standardize the technology of enzyme preparation products, speed up the formulation of relevant quality and safety standards and reliable functional labels, and publicize and popularize scientific common sense to consumers. Many people in the scientific community have made it clear that environmental enzymes are not as good as advertised in disinfection and sterilization. On the contrary, environmental enzymes are likely to form virus culture medium in cities, which is harmful to the environment and human health.
