Nitrite In Combination With Amines or Amides
Occurrence/Use
Nitrite is a natural constituent of fresh produce, including spinach and celery, and of fresh uncured meats. Nitrite salts are used to cure meats and meat products, and are used in brines to cure some fish and poultry products.
Amines are organic compounds that contain a basic nitrogen atom with a lone electron pair; examples include amino acids, the building blocks of protein, and biogenic amines like histamine.
Amides are organic compounds that can be formed from amines, and contain a nitrogen atom and an oxygen atom; examples include proteins.
