Sodium nitrate is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate.
Also called Pink curing salt #2. It contains 6.25% sodium nitrite, 4% sodium nitrate, and 89.75% table salt. [4] The sodium nitrate found in Prague powder #2 gradually breaks down over time into sodium nitrite, and by the time a dry cured sausage is ready to be eaten, no sodium nitrate should be left. [3]
Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable for the microbe growth that causes food spoilage. Curing can be traced back to antiquity , and was the primary method of preserving meat and fish until the late 19th century.
Death by sodium nitrite ingestion can happen at lower doses than the LD Lo. [53] [54] Sodium nitrite has been used for homicide [55] [56] and suicide.

Nigari was the first coagulant used to make tofu in Japan. [5] It is still used today because tofu made using bittern preserves the original flavor of the soybeans used to make it.
