Sodium tripolyphosphate can be mainly used as quality improver, water retaining agent, tenderizer, water softener, chelating agent, pH adjuster in food additives. Reasonable use of food grade sodium tripolyphosphate is harmless to food and human health. However, As long as food additives are added in accordance with national standards during food production and processing, consumers can rest assured. However, in the process of food production and processing, food additives must be added in accordance with food safety standards. Then consumers can rest assured of eating.
Analysis of Sodium Ttipolyphosphate Dosage
Generally, the added amount of rice, noodles, meat or frozen food cannot be more than 5g / kg. The amount of beverages and canned products cannot be more than 1g / kg
The maximum usage in canned Babao porridge, canned meat, fruit and vegetable juice (meat) beverages, protein beverages, tea beverages is 1g/kg.
The maximum usage in dairy products, poultry products, meat products, ice cream, instant noodles is 5g/kg.
When using compound phosphate, the content in canned meat products must not exceed 1.0g / kg in terms of phosphate, condensed milk must not exceed 0.50g / kg.
When sodium tripolyphosphate is used in combination with sodium pyrophosphate and sodium phosphate, the amount of phosphate should not exceed 5g / kg.
When using compound phosphate, the usage in smoked ham shouldn’t exceed 5g/kg. The mount used in western-style ham can be more appropriate, which can be up to 8g/kg in terms of phosphate.
The Role of Sodium Tripolyphosphate in Food
1.Peel softeners, which can soften the peels of vegetables and fruits quickly, shorten the cooking time and increase the extraction rate of pectin.
2.Anti-discoloring agents and preservatives, which can promote the decomposition of vitamin C and discoloration and discoloration of pigments, and can also prevent meat, poultry, and fish from spoiling, so as to extend the shelf life of food.
3.Used as bleach protector and deodorant, which can improve the bleaching effect and remove the odor in metal ions.
4.Used as antiseptic and bacteriostatic agents to inhibit the growth of microorganisms.
5.Emulsifiers, pigmented minced meat dispersants, anti-layering agents, and thickeners, which can disperse hardly soluble substances in water or stabilize suspensions to prevent the suspension from adhering and coagulating.
6.Used as strong buffering agents and preservatives control, which can maintain a stable pH range, make food taste more delicious, as well as control acidity and acid speed.
7.Used as water-retaining agents, softeners, and tenderizers, which have a strengthening effect on proteins and gelatins, so they can increase the hydration and water-retention of meat products, improve water permeability, promote food softening and improve food quality, as well s maintain good food quality Flavor.
8.Used as anti-agglomerating agents. In milk products, it can prevent the aggregation of milk when it is heated, and prevent the separation of milk protein and fat and moisture.
Sodium Tripolyphosphate Safe Use In Food
When it comes to food additives, many people think of preservatives and think it is bad for health. Food additives are actualy an artificial compound that is used to improve the color, taste of food and extend the shelf life of food. Without food additives, many foods in life will be harmful to health because of breeding bacteria. Adding preservatives to food can prevent or slow down the oxidation reaction of food, prevent food from spoiling due to microbial activity, and endanger the safety of consumers. STPP Chemical is added to foods such as meat, convenience foods, fruits, baked goods, soy sauce and vinegar, which can act as preservatives and antistaling agent. The addition of preservatives is not only to ensure the quality of food, but also to protect human health and safety.
