Is sodium hexametaphosphate a food preservative?
Microorganisms are ubiquitous in the daily environment, and of course there are also a certain amount of microorganisms in the food we eat. The microorganisms in most foods usually do not cause harm to the human body, and they may sometimes be used specifically to produce food. However, there is also a small part of microorganisms that can cause various diseases. Preservatives came into being, so that people can eat more high-quality, fresh food. Phosphates are widely used in food additives. Is sodium hexametaphosphate a food preservative?
Everyone knows the various claims about sodium hexametaphosphate in food additives, constantly stimulating the sensitive nerves of the public, and causing consumers to worry about the safety of food additives invisibly.
Is sodium hexametaphosphate a food preservative? What is sodium hexametaphosphate?
Sodium hexametaphosphate is a colorless powder or white fibrous crystal or glass block with strong deliquescence. It has strong chelating power, buffering effect and dispersing effect on metal ions, which can promote protein coagulation. In food additives, sodium hexametaphosphate can be mixed with other phosphates to form composite phosphates, or used alone. The aqueous solution of sodium hexametaphosphate is sprayed on the cured meat to improve the corrosion resistance.
In the production of meat products, in order to make the product shape complete, good color, tender meat, and shiny cut surface, some quality improvers such as food-grade sodium hexametaphosphate need to be added. This has a certain effect on increasing the water retention of meat, improving cohesiveness, improving the fresh and tender taste of the product, enhancing the elasticity of the product, and increasing the yield.
As the name implies, the role of food-grade sodium hexametaphosphate is to prevent food from spoiling. It delays the chemical changes of food by inhibiting the growth of microorganisms in food. On the premise of ensuring that the nutrition of the food is not lost, extending the shelf life of food is a quality improver in food ingredients.
