Sodium tripolyphosphate
Sodium tripolyphosphate is a common food ingredient often found on labels of processed foods. It is a synthetic compound derived from phosphoric acid and sodium carbonate, and it serves various purposes in food production.
In simple terms, sodium tripolyphosphate is made by combining phosphoric acid and sodium carbonate through a chemical process. This results in the formation of white granules or powder that is used in the food industry for its unique properties.
This ingredient appears on food labels primarily as a preservative and emulsifier. It helps to retain moisture in processed meats like sausages, improve the texture of canned seafood, and even enhance the shelf life of frozen seafood. Sodium tripolyphosphate is also used in some cheeses to prevent clumping and in certain beverages to help them dissolve more easily.
