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.
The combination of table salt with nitrates or nitrites, called curing salt, is often dyed pink to distinguish it from table salt. [7] Neither table salt nor any of the nitrites or nitrates commonly used in curing (e.g., sodium nitrate [NaNO 3], [8] sodium nitrite, [8] and potassium nitrate [9]) is naturally pink.
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]
One method uses molten sodium nitrate as the salt, and lead which is oxidized, while a more modern method uses scrap iron filings to reduce the nitrate. [4] [84] NaNO 3 + Pb → NaNO 2 + PbO. A more commonly used method involves the general reaction of nitrogen oxides in alkaline aqueous solution, with the addition of a catalyst. The exact ...

While it can be a quick and easy meal option, canned soup often comes with a hefty dose of sodium and preservatives. Many varieties also contain added sugars and trans fats to enhance flavor and ...
Nitrates help kill bacteria, produce a characteristic flavor, and give fish a pink or red color. [9] Nitrite is commonly used to speed up the curing of meat and also impart an attractive colour while having no effect on the growth of the Clostridium botulinum bacteria which causes botulism .
Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food ...
