Industrial salt is strictly forbidden to eat, and long-term intake of nitrite will increase the risk of cancer.
Nitrite is reductive and lively. Pickled meat, even stale meat products, can be bright-colored. Some unscrupulous and ignorant businesses in life pickle stale meat products with industrial salt, which leads to mass nitrite poisoning, so "industrial salt" is usually used to refer to nitrite.
Extended data
1 The salt mentioned in life refers to the salt extracted from seawater, salt ponds, salt wells and salt mines, and its main component is sodium chloride (NaCl), which is called sea salt, pond salt, well salt and rock salt respectively. In the past and in the future, human beings depend on these kinds of salts to ingest the inorganic salts we need.
2. With the development of chemical industry and chemical science, the meaning of the word "salt" has been greatly expanded. Middle school chemistry textbooks say that "salt" refers to a compound composed of "metal ions" (including ammonium ions) and acid ions. They have many kinds, different properties, different appearances and different uses.
3. "Industrial salt" is sulfate and nitrate. It is harmful, which leads to frequent ingestion of toxic salts and group food poisoning. The reason is that the cooks in many places, most of whom are migrant workers, think that "industrial salt" and "edible salt" are only the difference in quality. When there is no salt in the kitchen, they take what they think is salt (often sodium nitrite), which leads to great disaster. Therefore, the formulation of industrial salt must be abandoned, otherwise it will cause endless harm.
