How to identify the authenticity of potassium sorbate?

Potassium carbonate posing as potassium sorbate, First, potassium carbonate does not have antiseptic effect, would not achieve the antibacterial effect of potassium sorbate, because, since the inhibitory effect of sorbic acid root, instead of potassium. This shoddy products from entering the market, will damage the interests of dealers, users and consumers. Second, the products will change, affecting the sensory indicators. According to regulations, the appearance of normal potassium sorbate white. While the incorporation of potassium carbonate, potassium sorbate and stored for about three months after the color reaction, from white to yellow or brown, affecting sales.

Posing as potassium sorbate, potassium benzoate, potassium benzoate, although the anti-corrosion effect, but there are certain side effects on the human body, potassium sorbate, is recognized worldwide as safe food additives in the food production process, instead of potassium sorbate potassium benzoate and sodium benzoate, and help to improve food security, in line with the trend of healthy consumption.


Mixed with potassium carbonate, potassium sorbate products, stored for 3 months, the color will turn yellow or brown. Some unscrupulous companies will add in shoddy products of chemical raw materials brightener, in order to increase the whiteness of the product to cover up the yellow resulting in the deterioration. According to health experts, these chemical brighteners harmful to human health to serious harm.


The production of a number of small businesses and inferior potassium sorbate, just left the shop, the color is still white. Quality lowest potassium sorbate will change color, preservative effect, a special low price of potassium sorbate, is definitely poor quality.
According to insiders, product standards, imperfect, is shoddy potassium sorbate, the market is flooded with a fundamental reason. Chinas existing national standards of potassium sorbate is formulated on the basis of reference to the U.S. FCC standards. Among the national standards in China and the U.S. FCC standards, to determine the purity of potassium sorbate (content) is the potassium content measured.

Potassium sorbate, sorbic acid and potassium carbonate as raw materials made through chemical reaction of sorbic acid root and potassium ions combine to form potassium sorbate. The low price ratio of potassium carbonate and potassium benzoate, sorbic acid, add potassium carbonate in the product in violation.


Poor management and shoddy potassium sorbate to be a reason for existence. At present, health monitoring, quality supervision departments can the quality of the food additive regulation.

Since the potassium ion does not play a role in anti-corrosion, sorbic acid is the real root of the antibacterial factor to deal with the current national standard of potassium sorbate, modified and improved, will determine the purity of the standard potassium sorbate indicators changed to "Yamanashi radical content "(formerly the potassium content). Modify the standards, from product terminals to identify the genuineness of the product, sorbic acid radical content of non-standard "products can be sentenced to shoddy products, mixed with potassium carbonate or potassium benzoate products can not enter the market.
Potassium sorbate is made sorbic acid and potassium carbonate as raw materials, production technology is simple, one step reaction can be completed in a critical process, so, many small business owners, a little learning, can have the This technology, which is the number of small potassium sorbate producers are increasingly an important reason. Many small businesses crude production facilities, most of them only a few houses, a reaction vessel, a mixer, a few hand-sealing machines and other facilities, lack of cleaning devices, manufactured by hand, therefore, lower production costs, but the product of physical and chemical quality and hygiene quality is often unstable.
