Introduce
Sodium hexametaphosphate (SHMP) is a food additive chemically known as sodium hexametaphosphate. It is a salt compound consisting of six phosphate groups (hexametaphosphate) and sodium ions.SHMP is widely used in the food industry for a variety of functions and purposes.
The following are the main applications of Sodium hexametaphosphate in the food industry:
Chelating agent: SHMP has good chelating ability and can combine with metal ions to form stable complexes. It can inhibit the oxidation and catalytic effect of metal ions on food products and protect the colour, taste and quality of food products. Common applications include meat products, aquatic products, fats, oils and beverages.
Buffer: SHMP can regulate the pH of food and act as a buffer. It can help maintain food stability and prevent the effects of acid-base reactions on food quality. Common applications include seasonings, canned foods and beverages.
Melting Salt: SHMP can be used as melting salt in food processing. It improves the solubility and flow of foods, making them easier to process and mix. Common applications include dairy products, ice cream, meat products and seafood.
Water Retaining Agent: SHMP has good water retention properties, which can increase the water retention of food products and extend their freshness period. It is commonly used in foods such as meat products, seafood and pastries to improve the taste and quality of the food.
