Harm of potassium sorbate: the toxicity of potassium sorbate is only1/4 of that of benzoic acid, so it is very safe as long as the amount added in general food does not exceed the limit. If it exceeds the limit seriously and is taken for a long time, it will inhibit bone growth to some extent and endanger the health of kidney and liver.

Potassium sorbate, colorless to white scaly crystals or crystalline powder, odorless or slightly odorous. Unstable in air. Can be oxidized and colored. Molecular weight 150.22. It is hygroscopic. Soluble in water and ethanol.

Properties of potassium sorbate:

1, corrosion resistance

Sorbic acid (potassium) can effectively inhibit the activities of mold, yeast and aerobic bacteria, and also prevent the growth and reproduction of harmful microorganisms such as Botox, Staphylococcus and Salmonella, but it is almost ineffective for beneficial microorganisms such as anaerobic Bacillus and Lactobacillus acidophilus.

Its function of inhibiting development is stronger than sterilization, so as to effectively prolong the storage time of food and maintain the flavor of the original food. Its anti-corrosion effect is 5- 10 times that of the similar product sodium benzoate.

2. The fire site emits pungent smoke containing potassium oxide. It has a strong inhibitory effect on spoilage bacteria and mold, and has become the most important preservative in the world because its toxicity is far lower than other preservatives. It can give full play to the anti-corrosion effect under acidic conditions, but it has very low effect under neutral conditions.
