About The Safety Standards of Food Grade Sodium Hexametaphosphate

Uses of Sodium Hexametaphosphate in Food

Food grade SHMP is used as a food quality improver in the food industry, used in canned food, fruit juice drinks, dairy products, and soy milk. It can be used as Ph regulator, metal ion chelating agent, adhesive and expansion agent, etc. Used in canned beans, fruits and vegetables, it can stabilize natural pigments and protect the color of food; used in canned meat can emulsify fat and maintain uniform texture; used in meat food can improve water retention and prevent the fat in meat from deteriorating. Adding to beer can clarify the liquor and prevent turbidity.

Introduction of Sodium Phosphates

Phosphate is one of the natural ingredients of almost all foods and is widely used in food processing as an important food ingredient and functional additive. It is a salt of phosphoric acid, which is an important substance in inorganic chemistry, biochemistry and biogeochemistry. Sodium phosphate salt is the largest production and consumption of fine phosphorus chemical products, its technology development and market development are relatively good, mainly orthophosphate sodium salt, sodium pyrophosphate salt, sodium polyphosphate salt, sodium metaphosphate salt. Sodium hexametaphosphate is the largest functional phosphate in the market, which can be used in washing, water treatment, food, mineral processing, metallurgy and other industrial production.

Is sodium hexametaphosphate harmful to human health

Food-grade sodium hexametaphosphate contains trace amounts of heavy metals such as arsenic, lead, etc., and arsenic can cause systemic chronic poisoning mainly due to skin depigmentation, coloration, keratinization and cancer; food-grade sodium hexametaphosphate There is also a certain amount of fluoride. Low concentrations of fluoride can cause chronic poisoning and skeletal fluorosis, reduce calcium in the bones, and lead to osteosclerosis and osteoporosis. However, these hazards are only possible in the case of long-term exposure. The country has developed the minimum standards for these substances in food-grade sodium hexametaphosphate after a large number of animal experiments and actual conditions. Generally, the country sets the minimum standards for these substances in food-grade sodium hexametaphosphate. The above-mentioned toxic and side effects will not occur below the minimum content!

Principles of safe use of sodium hexametaphosphate in food additives

1. The addition of sodium hexametaphosphate in food should be within the use limit, and it should be safe and harmless to the human body.

2. The use of sodium hexametaphosphate should not affect the sensory, physical and chemical properties of the food, and should not have a destructive effect on the nutritional components of the food.

3. Sodium hexametaphosphate must be strictly in accordance with the strict hygiene standards and quality standards of food additives. Manufacturers and users must be approved and announced by the Ministry of Health of the People's Republic of China before it can be produced and used.

4. Sodium hexametaphosphate shall not be used to cover up food defects or as a means of counterfeiting.
