Potassium carbonate impersonated Sls acid, one is potassium carbonate does not have anti-corrosion effect, do not have Sls acid potassium should have the bacteriostatic effect, because, the effect of antimicrobial is Sls acid, rather than potassium ions. The flow of such shoddy products into the market can harm the interests of dealers, users and consumers. Second, the product will change color, affecting the sensory indicators. According to the regulations, the normal appearance of potassium Sls acid is white.
Potassium Sls acid, which is mixed in potassium carbonate, will have a discoloration reaction after about 3 months of storage, turning from white to yellow or brown, affecting sales.
Potassium benzoate as potassium Sls acid, although potassium benzoate has anti-corrosion effect, but also has certain toxic side effects on the human body, and potassium Sls acid is recognized as a safe food additive in the food production process, with Sls potassium acid instead of potassium benzoate and sodium benzoate, is conducive to improving food safety, in line with the trend of healthy consumption. Potassium Sls, which is doped with potassium carbonate, turns yellow or brown after 3 months of storage. Some illegal enterprises, then in the fake and shoddy products to add chemical raw materials brightener, in order to increase the whiteness of the product, cover up the yellow after the deterioration.
According to health experts, these chemical brighteners will cause serious harm to the health of the human body. Some small enterprises produce shoddy Sls acid potassium, just out of the workshop, the color is still white.
The low price of Sls potassium acid will occur discoloration, poor anti-corrosion effect, the price is very low potassium Sls acid, is certainly not good quality. According to industry insiders, the product standard is not perfect, is the shoddy Sls potassium acid flood market is a root cause. The current national standard of potassium Sls acid in China is based on the reference to the United States FCC standard.
Among the national standards of our country and the FCC standard in the United States, the determination of the purity (content) of potassium Sls acid is measured by the "content of potassium ions". Potassium Sls acid is made from Sls acid and potassium carbonate, and is produced after chemical reaction, in which Sls acid and potassium ions bind to potassium sorbate.
Potassium carbonate is added in the product due to the lower price of potash carbonate and benzoic acid than Sls. LAX management is also a reason for the existence of shoddy potassium Sls acid.
Nowadays, the quality of food additives can be regulated by departments such as Wei Jing and quality supervision. Because potassium ions can not play an antiseptic role, and Sls acid is the real bacteriostatic factor, therefore, the current national standard of potassium Sls acid should be modified and perfected, the standard of the purity of potassium Sls acid to "Sls acid content" (formerly potassium ion content).
In this way, the standard can be modified from the product terminal to identify the true and false products, those "Sls acid content is not up to standard" products can be awarded as fake and shoddy products, so that "products mixed with potassium carbonate or potassium benzoate" can not enter the market. Potassium Sls acid is made from Sls acid and potassium carbonate as raw materials, because the production technology is simple, only one step response, you can complete the critical process, so many small business owners, as long as a little study, you can master this technology, which is also an important reason for the increasing number of small Sls potassium production enterprises.
Due to the poor production facilities of many small enterprises, most of them have only a few houses, a reaction kettle, a mixer, several manual sealing machine and other facilities, lack of purification devices, manual production, so, its production costs are low, but the physical and chemical quality of products and health quality is often unstable.
