Whether there is formaldehyde in the food you buy on Meituan or on Taobao, you must first understand the formaldehyde in the food. First of all, formaldehyde in vegetables can be divided into two categories: endogenous and exogenous. Endogenous formaldehyde is produced during biological metabolism and is naturally present in many foods, such as vegetables, mushrooms, fruits, meat, fish, etc. The content of this type of formaldehyde is very small and it basically does not cause harm to the human body. Exogenous formaldehyde is improperly used or added illegally during food processing, transportation, and sales. This is the main cause of formaldehyde pollution in food. Formaldehyde has been used as a preservative and bleaching agent in the past. The claim that formaldehyde is contained in fresh vegetables such as enoki mushrooms and baby cabbage mainly comes from the fact that unscrupulous merchants added formaldehyde in the past to extend the storage time and prevent vegetables from spoiling. my country's "Food Safety Law" and "Agricultural Products Quality and Safety Law" clearly stipulate that formaldehyde shall not be produced, operated and used as a food processing aid. In other words, it is illegal to add formaldehyde to food in any way.

With the advancement of food technology, there are many methods for antiseptic storage. However, formaldehyde has a strong irritating smell and is easy to detect. There is no need for merchants to take huge risks in using it. Therefore, even if there is "formaldehyde dish", it is only an isolated phenomenon.
