A certain amount of desiccant is added to the packaging of melon seeds, biscuits and other products. These things are not edible, and some desiccants are even harmful and poisonous. So what kind of desiccant is used in the melon seed packaging? Let the editor of Shenzhen Mingwei Industry tell you.
Desiccant is a substance with strong adsorption capacity. Although the food itself has the ability to absorb water, the water absorption charm cannot compete with the desiccant, and it cannot attract any water molecules, so it has to be dried.
At present, silica gel desiccant and lime desiccant are mainly used as food desiccants. Silica gel desiccant is non-toxic and non-polluting. The most important thing is that it is not absorbed by the human body. It can be discharged through feces if swallowed. This kind of desiccant can be accepted by customers. Therefore, most foods use this kind of desiccant; lime desiccant meets water It heats up, so it has certain hazards, but it has a strong water absorption capacity, so it can also be used as a member of food desiccants.
When we are buying melon seeds, if we see that the desiccant is a transparent bead type, it is a non-toxic and non-polluting silica gel desiccant. Quicklime desiccant is a white powder, which is very corrosive, so remember to place it in a place that is not easy for children to touch!
