what is sodium tripolyphosphate used for in food

Sodium Tripolyphosphate (STPP) is a food additive, a white crystalline powder, which is used as a pouring agent, quality improvement agent, and stabilizer used in food processing. It can increase the texture and stability of food, improve the color and taste of food, maintain the freshness of the food, and extend the life of the shelves. However, long-term excessive intake of Sodium Tripolyphosphate may have a certain negative impact on human health.

Sodium tripolyphosphate can be summarized as the following points in food:

1. Polygin agent: Sodium tripolyphosphat can react with the water in the food, and produce carbon dioxide Food additive Sodium Tripolyphosphate (STPP) is a white crystalline powder, which is often used as a puffing agent, quality improvement agent, and stabilizer in the food processing process. It has a variety of functions, including increasing the texture and stability of the food, improving the color and taste of food, maintaining the freshness of the food, and extending the life of the shelves.air bubbles, thereby increasing the volume and fluffiness of the food. It makes baked goods such as breads, cakes and doughs softer and taste better.

2. Prevent water loss: Sodium tripolyphosphate can be combined with water in food to form stable complexes, thereby reducing moisture loss and evaporation, and maintaining the moistness of food. Especially in the processing of meat products and seafood, it can help maintain its original moisture content and tender taste.

3. Keep food color: Sodium Tripolyphosphate can be combined with metal ions in food to reduce the impact of metal ions on the color of food so that the food is bright. It is often added to meat products, seafood, and aquatic products to delay the change and fading of color.

4. Stabilize pH: Sodium Tripolyphosphate is a weak alkaline substance that can neutralize the acidic ingredients in food and regulate the pH of food. This is very important for increasing the stability of food and extending the life of the shelf.

5. Antioxidant: Sodium Tripolyphosphate can be combined with oxygen to reduce oxidative response to food to food and inhibit the deterioration and corruption of food. This is particularly important for some oxidized foods such as oil and meat products.

Some studies have found that excessive intake of Sodium Tripolyphosphate may cause intestinal flora dysfunction, intestinal mucosal damage, increased kidney burden, and even adversely affect bone health. Therefore, the use of food additives should follow relevant national standards and regulations, and pay attention to reasonable use to avoid long-term excessive intake.

In short, food additives Sodium Tripolyphosphate has a variety of functions in food processing, including increasing volume and fluffiness, maintaining moisture, maintaining color, regulating acid and alkali, and antioxidants. However, long-term excessive intake may hurt human health, so it should be used reasonably and follow relevant national standards and regulations.
