In fact, food additives are not so terrible, because they are widely used in dailylife. Food additives are indispensable ingredients in food processing.Sodiumtripolyphosphate(STPP)is an indispensable ingredient in food processing. As long as itis used in accordance with the regulations, it is very safe, and consumers can restassured that it is edible.

　　The production of food additives must undergo strict evaluation and testing, and aseries of experiments must be carried out for comprehensive evaluation. It can beapproved to use after determining that there is no potential safety hazard to the body.For example, STPP has strict use control in food processing. Usually, the added amountof rice, noodles, meat or frozen foods should not exceed 5g/kg, and the added amount ofbeverages and canned products should not exceed 1g/kg to ensure the safety of humanconsumption.

　　Food grade STPP is mainly used as a quality improver. It can improve the binding forceand water holding capacity of food by improving metal ions, adjusting pH value andincreasing ionic strength. It can also be used as quality improver and water retentionagent for meat products, fruit juice drinks, beer, dairy products, soybean products,etc. It is used for ham and canned food to soften meat and increase adhesion force; itis used for aquatic products to gain weight and keep fresh; it is used for milkproducts to prevent protein from coagulating and precipitating; it is used to preventthe oxidation, deterioration, color change of beverages and the decomposition ofvitamin C; it is used to modify soybean protein to strengthen the function of soybeanprotein; it is used to soften the skin of fruits, vegetables, canned faba beans, etc.It can also be used as softener and thickener.

　　Food producers mislead consumers by improper propaganda. Flaunting that its products donot contain "food additives" implies that foods with "food additives" are harmful orharmful to human health. As a result, people have a wrong understanding of foodadditives. Consumers should not be one-sided to understand food additives, blindlybelieve that additives are only harmful to human health.
