Pure sodium tripolyphosphate cannot be consumed, but it can be consumed as a food additive if it meets national standards. Sodium tripolyphosphate is a commonly used additive in many foods in China, which can be used as a water retention agent, softener, pH regulator, and thickener in food. For example, adding sodium tripolyphosphate to vegetables, fruits, and fruit juice can soften the flesh of vegetables and fruits, and regulate the acidity and alkalinity of fruit juice. There are also boxed milk and other beverages that are frequently consumed in daily life, and a certain amount of sodium tripolyphosphate is added to these beverages, which can play a certain role in thickening and maintaining moisture. Usually, any food that is produced formally and within the normal shelf life can be consumed normally.
The general dosage of additives is within the safe range and will not cause harm to the human body. But if it is sodium tripolyphosphate contained in detergents, it is usually not edible because the sodium tripolyphosphate in detergents does not meet the edible standards, and there are many other components in detergents. If ingested, it may have an impact on the human body. For example, some people may experience gastrointestinal reactions such as nausea and vomiting, and it is often necessary to seek medical attention in a timely manner and receive treatment such as inducing vomiting.
Sodium tripolyphosphate, also known as trisodium polyphosphate, belongs to the category of phosphate food additives. In food processing, sodium tripolyphosphate mainly plays a role in anti-corrosion and moisturizing.
Sodium tripolyphosphate can reduce the water activity of food, thereby inhibiting the growth of bacteria and mold, and extending the shelf life of food. In addition, sodium tripolyphosphate can also absorb moisture from food, improve its moisturizing properties, and make the taste of food more fresh and tender.
Sodium tripolyphosphate is widely used in various foods, such as meat products, seafood products, canned foods, cakes, biscuits, etc. It can be used for dried food, frozen food, sushi, etc
