Sodium Tripolyphosphate (STPP) is a food additive that is widely used in the food industry for various purposes. It is a white, crystalline powder that is soluble in water and has a strong alkaline taste. STPP is a salt of phosphoric acid and is commonly used as a preservative, emulsifier, and sequestrant in food production.

Preservative: STPP is used as a preservative in various food products such as seafood, meat, and poultry. It helps to prevent spoilage by inhibiting the growth of bacteria and other microorganisms that can cause foodborne illnesses. STPP also helps to maintain the color, texture, and flavor of the food.

Emulsifier: STPP is used as an emulsifier in food products such as processed cheese, salad dressings, and sauces. It helps to stabilize the mixture and prevent separation of the ingredients.

Sequestrant: STPP is used as a sequestrant in canned fruits and vegetables. It helps to prevent discoloration and maintain the texture of the food by binding with metal ions that can cause oxidation.

STPP is considered safe for consumption by the US Food and Drug Administration (FDA) and is widely used in the food industry. However, excessive consumption of STPP can lead to health problems such as nausea, vomiting, and diarrhea. Therefore, it is important to consume STPP in moderation and as per the recommended dosage.
