Food grade sodium hexametaphosphate is a common additive in modern daily life. It can be seen in many foods purchased from supermarkets and e-commerce. The effect of adding food grade sodium hexametaphosphate is mainly to inhibit the reproduction of microorganisms in food, prevent food deterioration and prolong the shelf life of food. However, sodium hexametaphosphate should not be added too much or too little in food, and the relevant regulations of the state must be followed. 

Microorganisms cover a wide range of beneficial and harmful substances, including food, medicine, industry and agriculture, environmental protection, sports and many other fields. If the microorganisms added in food are in accordance with national standards, it will not be harmful to human body, but if excessive, it will affect human health. If too little, not to the shelf life of food mildew, will also make users poisoned or harmful to health.

Food is easily contaminated by microorganisms in the process of production, processing, transportation and storage. When the ingredients in food are combined with microorganisms, the microorganisms will cause food to deteriorate and rot gradually, thus shortening the shelf life of food.

In fact, the state law allows food additives to be used in the production and processing of food, but to follow the relevant strict regulations can make people feel at ease and safe to eat. At present, phosphate food additives on the market include sodium hexametaphosphate, sodium tripolyphosphate and sodium pyrophosphate, which can be used alone or in combination.

Sodium hexametaphosphate is a commonly used quality improver in food additives. It is used in meat products, fish sausage, ham, etc. It can improve water holding capacity, increase binding property and prevent fat oxidation. Soy sauce and soy sauce can prevent discoloration, increase viscidity, shorten fermentation period and adjust taste. It can be used in fruit beverages and cool drinks to improve water holding capacity. The juice yield, viscosity and vitamin C decomposition can be increased; the ice cream can improve the expansion ability, increase the volume, enhance the emulsification function, prevent the paste damage, improve the taste and color; prevent dairy products and beverages from gel precipitation; add beer to clarify the liquor and prevent turbidity; used for canned beans, fruits and vegetables, can stabilize the natural. Pigment protects food color. In addition, spraying sodium hexametaphosphate aqueous solution on cured meat can improve the anti-corrosion performance. Dosage: 0.3-0.5% in general, 0.9% in cheese, 0.3% in meat, 0.5% in milk powder, butter powder, frozen fish and shrimp, 0.2% in condensed milk and beverage.
