food preservative potassium sorbate granular

Potassium sorbate potassium sorbate, also known as 2, 4-hexadienoate potassium, is the potassium salt of sorbate, a kind of Food Preservative, the molecular formula is C6H7O2K, white to light yellow scaly crystals, crystal particles or crystal powder, odorless or slightly smelly, easy to absorb moisture in the air for a long time, oxidative decomposition and discoloration.  Soluble in water, propylene glycol and ethanol.  It is often used as a preservative, destroying many enzyme systems by binding to the sulfhydryl groups of microbial enzyme systems. It is much less toxic than other preservatives and is now widely used.  Potassium sorbate can give full play to its anticorrosive effect in acidic medium, but has little anticorrosive effect in neutral condition. We Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide, Hydrogen Peroxide and Silane etc. since 2007. 

Potassium sorbate can effectively inhibit mold, yeast and oxygen activity of bacteria, also prevent botox, staphylococcus aureus, salmonella and other harmful microorganism growth and reproduction, but for anaerobic bacillus bacteria and lactobacillus acidophilus beneficial microbes such as null and void, almost against the effect of development was stronger than the sterilization effect, so as to effectively prolong food to save time, And keep the flavor of the original food. Its antiseptic effect is 5-10 times that of similar products sodium benzoate. At present, it has been widely used in food, beverage, pickles, tobacco, medicine, cosmetics, agricultural products, feed and other industries. From the development trend, its application scope is still expanding.

Property and Composition

Production process

There are two main synthesis methods of sorbic acid, one is the reaction of butenal with acetone under specific conditions, and the other is the reaction of butenal and ketone as raw materials under specific technological conditions, which is the most commonly used synthesis method.  Butenal mainly comes from the condensation of acetaldehyde, while ketene is formed by the cracking of acetic acid, and further by the reaction of sorbate with potassium hydroxide to form potassium sorbate. 

Potassium sorbate is mainly used as a food preservative. It is widely used because of its strong inhibition of mold and spoilage bacteria, and it is easily dissolved in water.  Potassium sorbate has been recommended by the Food and Agriculture Organization of the United Nations as a safe and efficient food preservative.  Potassium sorbate has low toxicity, good mildew proof effect, does not change the original nature of food, easy to use, wide application range and other characteristics, so many foreign developed countries have taken potassium sorbate as a good, efficient preservative, a large number of applications in food.  At present, potassium sorbate has been widely used in the domestic food industry. With the continuous breakthrough of production cost and production technology, potassium sorbate, as a low-toxicity, safe and efficient food preservative, will continue to expand its application scope
