Food Additive Preservative Potassium Sorbate CAS 24634-61-5

Food Additive is a kind of substance to improve the food color, taste or prolong its preservative time, 
Normally Food Additives List is well known such as Stabilizer For Food, Emulsifier For Food and flavor enhance etc.
In terms of Leavening Agent , which mainly refer to leavening agent in food, they are also called as Food Swelling Agent, or Food Raising Agent especially the Cake Raising Agent ;

Basic introduction:

Potassium sorbate potassium sorbate, also known as 2, 4-hexadienoate potassium, is the potassium salt of sorbate, 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

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. The reaction formula is as follows 

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
