At present, most snacks on the market have a desiccant in a small package. Its main function is to prevent the food from getting damp and moldy. However, due to the frequent occurrence of desiccant injury incidents, the desiccant has attracted everyone's attention. What is the hazard of desiccant? The following editor of Shenzhen Mingwei Industrial will introduce the hazards and prevention of desiccant:

Cheap desiccants are the most dangerous

It is understood that most of the desiccants currently on the market use calcium oxide (quicklime), silica gel, ferric oxide, and calcium chloride as the main raw materials. Among them, desiccants using quicklime and silica gel as raw materials are the most common. Especially quicklime, because of its good moisture absorption effect, convenient source and low price, so most of the desiccants are quicklime, which is widely used in food packaging. Therefore, most of the snacks are lime desiccants. This kind of desiccant will cause severe heat when exposed to water, which will burn the eyes and skin. Ingestion will also burn the stomach and intestines, which is very dangerous. Because the children don't know the principle, they feel it's fun to put bubbles in the water, which leads to accidental injury. All the news that desiccants hurt people is actually caused by lime desiccant.

In recent years, as an alternative to lime desiccant, silica gel desiccant has become popular. Its main component is silica, which is non-toxic, non-corrosive, stable in shape and has good moisture absorption. At the same time, silica gel is also the only desiccant that has passed the US FDA certification and can be used in direct contact with drugs and food.

In the process of using lime desiccant, once it encounters water, it will heat up and swell, and will burn the stomach and intestines if swallowed. This is one of the reasons why it is gradually eliminated. In addition, according to the food and drug packaging regulations, the main components and harmful conditions of the desiccant should be marked on the outer packaging of the desiccant, and safety instructions should be made. Judging from the current market survey, food companies generally mark the desiccant package with warning words such as "not edible" and "keep away from children". When parents eat snacks, they must remove the desiccant first before giving them to the children. Avoid children to play with, so as to avoid danger.
