Food Applications:
Sodium tripolyphosphate is also used to preserve foods such as red meats, poultry, and seafood, helping them to retain their tenderness and moisture during storage and transport. Pet food and animal feed can also be treated with it, serving the same general purpose as it does in human food. STPP also has been used to help preserve the quality of drinks such as milk and fruit juices.
Because sodium tripolyphosphate can improve the appearance of seafood like shrimp andscallops, there is some concern that unscrupulous salespeople may sell products that are not fresh to consumers who cannot see the signs that the items have started to go bad. Although it cannot be used specifically for this purpose, this chemical also holds in water, making the seafood heavier and therefore more expensive. Some food quality experts recommend asking a fishmonger or other salesperson for seafood that has not been treated with this chemical. Some stores will mark products that have not been exposed to STPP as "dry."
