1. Potassium sorbate

Potassium sorbate, the potassium salt of sorbic acid, CAS No. 24634-61-5, EINECS No. 246-376-1 Chemical formula C6H7KO2, Molecular weight 150.22.

White to light yellow scaly crystals, crystal particles or crystal powder, odorless or slightly smelly, easily absorbed moisture and discolored by oxidation when exposed to air for a long time. It’s soluble in water, soluble in propylene glycol and ethanol. Often used as preservative.

2. Appearance of potassium sorbate

There are 3 kinds of appearance of potassium sorbate: noodle or granular, powder and pellet.

3. How is potassium sorbate preserved?

The preservative mechanism of potassium sorbate is the same as that of sorbic acid, that is, it combines with the sulfhydryl group of microbial enzyme system and thus destroys the action of many enzyme systems. Potassium sorbate can effectively inhibit the activity of mold, aerobic bacteria and yeast, and prevent the reproduction of microorganisms such as Staphylococcus, Clostridium botulinum and Salmonella, but it is ineffective against anaerobic Bacillus and Lactobacillus acidophilus, etc. The inhibition of development is stronger than its sterilization effect, thus achieving the purpose of prolonging the shelf life of food while maintaining the original flavor of food.

4. Effective PH range of potassium sorbate

Potassium sorbate is an acidic preservative, and still has a good preservative effect in food close to neutral (6.0-6.5).
