Sodium tripolyphosphate is indispensable to good detergent additives, Sodium tripolyphosphate mainly of metal ion chelation, improve peptization, buffer, to prevent the agglomeration effect. Sodium tripolyphosphate used as a cleaning product additives can also be used in petroleum, metallurgy, mining, paper and water treatment. Sodium tripolyphosphate main auxiliaries for synthetic detergent, synergist for soap and prevent precipitation of soap and oil from the cream. E451i on strong oil and fat emulsification, can be used to adjust the PH value of the buffer liquid soap. Sodium tripolyphosphate for industrial water softener. Tanning agent. Dyeing auxiliaries. Paint, kaolin, magnesium oxide, calcium carbonate and other industries made the preparation of suspension dispersant. Drilling mud dispersants. Sodium tripolyphosphate anti-oil agent for the paper industry.

Yes, food grade STPP is a multiple purpose ingredient that is generally recognized as safe (GRAS) when used in food in accordance with good manufacturing practice by the U.S. Food and Drug Administration (FDA) (2).

Also, the safety of STPP has been approved by the European Food Safety Authority (EFSA) and it is an authorized food additive in the European Union (EU) and can be used as a carrier in the preparations of the colour anthocyanins, also applied in the salted fish of the Gadidae family (3), as well as by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) as a sequestrant, texturizer, and thickener. (4)

However, some consumers think it is bad for our health as it is a chemical used in detergents that cannot be eaten, and along with other possible side effects, such as allergy reactions.

Conclusion
Now you may have a good knowledge of the food additive – Sodium Tripolyphosphate (E451i, STPP), from production, uses in fish and meat, approved safety, possible side effects and so on.

Have you noticed this ingredient in the fish shops and seafood restaurants, or in the labels of other kinds of food packagings? Let me know in the comments.

1, for medicine, regulating acid-base balance of the body to restore normal nerve function, sodium and capacity to maintain extracellular osmotic pressure, regulate acid-base balance of normal neuromuscular function play an important role. This product can effectively prevent the occurrence of low sodium syndrome. For the same purpose, used in food additives
2, used as water quality stabilizer: sodium gluconate as excellent corrosion and scale effect, it is widely used in water quality stabilizer, such as oil and chemical companies circulating cooling water system, low pressure boilers, internal combustion engine cooling water system treatment chemicals . Its superiority in:
a. the coordination obvious effect. For molybdenum, silicon, phosphorus, tungsten, nitrite and other formulations, as the coordination effect of corrosion inhibition effect is greatly increased.
b. Corrosion rates increase with rising temperature. General corrosion inhibition efficiency increased with increasing temperature decrease, or even useless. However, sodium gluconate on the contrary, corrosion rate within a certain range increase with increasing temperature, for example, carbon steel and other materials for the test, the temperature from 77 ℃ F at up to 120 ℃ F, the average rate of 5% buffer or more. Therefore, sodium gluconate this strange feature, the system of higher temperatures from cryogenic to high temperature or variable temperature system, is ideal as a corrosion inhibitor.
c. ability scale: for calcium, magnesium, iron salts are highly complex, and they scale are strong, especially for Fe3 + has excellent chelation, even in a role within the whole range of PH.
d. pollution. Using sodium gluconate as the circulating cooling water corrosion inhibitor, to pollution, which is currently used by other corrosion inhibitor incomparable advantages.

Yes, it has been approved safe by the U.S. Food and Drug Administration (FDA) and European Food Safety Authority (EFSA), as well as the Joint FAO/WHO Expert Committee on Food Additives (JECFA).


FDA
Sodium gluconate is generally recognized as safe (GRAS) when used as a sequestrant in food. (6)

EFSA

Sodium gluconate (E576) is listed in Commission Regulation (EU) No 231/2012 as an authorised food additive and categorized in “ additives other than colours and sweeteners” (7).

As a high quality and efficiency food emulsifier,it’s widely used as good emulsification,distribution, and stabilization in food. It has been used in the industry areas of food, medicine, household chemicals ,plastic, packaging and cosmetic etc., It is also a safe food additives which is completely non-toxic and harmless, and there is no restriction intake by the human body . DMG is the safety and high quality food additives.
Properties:
(1)Good Emulsifying, Dispersing, Stabilizing Properties
In the food processing oilwater separation often occurs, in order to improve product quality and prolong shelf life. Emulsifier is usually added during the procession, it will stabilize the mixed phase, and form a uniform emulsion. So that to avoid and prevent oilwater separation, stratification, precipitation happen in food and beverage.
