What You Need to Know
Salt draws out moisture, lowering water activity and slowing microbial growth. Sodium nitrite is reduced to nitrite, which reacts with myoglobin to form nitrosyl hemochrome, giving cured meats their pink hue and antioxidant properties. Precise salt and nitrite levels are essential to balance safety, flavor, and texture.
