Problems solved by technology

[0003] There are many kinds of disinfectants, but most of them are chemical preparations with certain toxicity. Food safety problems caused by the residue of toxic chemical components cannot be guaranteed; in recent years, the use of natural plant ingredients to prepare safe and side-effect-free disinfectants has become a hot topic in the field of food safety. There are also several plant-based disinfectant products on the market. However, these products are not as good as all the ingredients of the disinfectant are natural ingredients, so directly spraying on the surface of the food cannot completely guarantee the safety of the food; in this context, the food safety field needs a safe pure natural plant ingredient The prepared disinfectants, and new natural disinfectants with broad-spectrum sterilization are also needed
