What is the role of sodium nitrite?

Sodium nitrite is a kind of industrial salt, it is a white opaque crystal, the shape is very similar to salt. And nitrite is harmful to human body, it will make people lose the ability to transport oxygen, and cause tissue hypoxia damage. Nitrite is not only a carcinogen, it is likely to be toxic if it is used for a long time.

The addition of nitrite will make nitrite residues in meat products enter the human body, and the amines generated in certain environment and conditions will react to form nitrosamines. Nitrosamine has a strong carcinogenic effect, which will bring harm to the health of consumers. We must take an appropriate amount of nitrosamine.

matters needing attention
