Potassium Sorbate in food industry

Potassium Sorbate can effective to inhibit mold, yeast bacteria and aerobic bacterial activity, it also can prevent the growth and breeding of harmful microbial such as meat HIV Bacillus, Staphylococcus, salmonella, etc. But it is almost invalid to useful microbial like anaerobic spore bacteria, Lactobacillus Acidophilus and so on, its role of suppress growth is stronger than sterilization so as to effectively prolong the preservation time of food and keep original food flavor. The antiseptic effect is 5-10 times of the sodium benzoate. The high level security and a better stability make it a very wide range of uses!

Potassium Sorbate is an efficient and safe preservative recommended by international FAO and the World Health Organization. It is widely used in food, beverage, tobacco, pesticides, cosmetics and other industries. As unsaturated acid, it can also used for resins, spices and rubber industries. Potassium Sorbate is recognized as the most safety food preservatives in various preservatives in worldwide, it is straight-chain structure of carbon hydrogen and oxygen, and it eventually breaks down into carbon dioxide and water after it enter into the body, but there is no residue in the human body. Its toxicity is 1/2 of the salt, as well as 1/40 of another widely used food preservative sodium benzoate. With the improvement of food safety awareness, potassium Sorbate are expected to gradually replace the use of sodium benzoate.

Potassium Sorbate can be directly spraying, dipping, powder spray, handling in package materials, etc. When it comes to non-ionic surface active agents and plastic, the antimicrobial activity of potassium Sorbate will be reduced. Salts of heavy metals can catalyze the oxidation reaction. Sorbic acid can react with sulfur-containing amino acids, but the reaction can be inhibited by adding vitamin c, propyl ester of Gallic acid or butylated hydroxytoluene.

This solution is very sensitive to pH when it is saved in the glass containers. Therefore, it needs to detect micro-organisms if use potassium sorbic acid as a preservative agent in store for a long amount of time. If sorbic acid solution is saved in pp, PVC or polyethylene containers without adding antioxidants, sorbic acid will degrade. If you have interest to OKCHEM Inc., click here thanks!
