Is it true that baby cabbage contains formaldehyde?

Formaldehyde aqueous solution is what we commonly call formalin. It has the functions of antisepsis, disinfection and bleaching, and its most well-known use is for preparing specimens. Looking at it this way, it seems more reasonable to use it to soak vegetables and keep them fresh-if the cost is not considered.

Nowadays, when merchants transport vegetables, it is a routine operation to spray disinfectants and fungicides to keep vegetables fresh. Commonly used broad-spectrum fungicides, such as prochloraz, are not particularly expensive. In order to use formaldehyde aqueous solution instead of fungicides, businesses violated laws and regulations, did not save much economically, and risked their own health. It was not a cost-effective choice.

Whether it is shopping for food or decorating, after all, it is harmful to the body. In daily life, it is best to eliminate formaldehyde.

However, before removing formaldehyde, a more thorough method should be to choose regular merchants and products, and avoid buying building materials with excessive formaldehyde, or fruits and vegetables with excessive formaldehyde, etc. Daily cooking, using disinfectant, smoking, etc. will also produce formaldehyde. At this time, you should pay attention to healthy living habits, do not smoke, eat less fried food, and pay attention to indoor ventilation when using disinfectant or washing fruits and vegetables.

There are four principles for removing formaldehyde in daily life: high temperature, high humidity, long time, and plenty of ventilation. Formaldehyde gas is volatile and easily soluble in water. The high temperature and high humidity environment is conducive to the rapid departure of formaldehyde. Extending ventilation for a long time uses air flow to reduce indoor formaldehyde concentration.
