Introduce
Sodium Acid Pyrophosphate (SAPP) is a food additive chemically known as disodium hydrogen pyrophosphate. It is a salt compound obtained by the reaction of pyrophosphoric acid (pyrophosphate) and sodium hydroxide.SAPP is widely used in the food industry for a variety of functions and purposes.
The following are the main applications of Sodium Acid Pyrophosphate in the food field:
Bulking agent: SAPP is commonly used as a bulking agent in the production process of baked goods such as bread, cakes and biscuits. It can react with alkaline substances (e.g. baking soda) to release carbon dioxide gas, which promotes the expansion of dough and increases the volume and fluffiness of food.
Buffer: SAPP has a buffering effect and can regulate the pH of food. It can help maintain food stability and prevent the effects of acid-base reactions on food quality. Common applications include spices, canned foods and meat products.
Chelating agent: SAPP can form stable complexes with metal ions, thus inhibiting the oxidative and catalytic effects of metal ions on food. This is very important to protect the colour, taste and nutritional value of food. It is commonly used in meat products, aquatic products, fats, oils and beverages.
Turbidity preventing agent: SAPP can be used as an agent to prevent turbidity in food. It binds to polyvalent metal ions in food and prevents them from forming precipitates and turbid substances. This is useful in products such as juices, beverages and canned foods.
