potassium sorbate is a preservative primarily against mold and yeast, and used in concentrations of 0.025 to 0.2 percent. It is non-toxic but may cause mild skin irritation.

Production methods

1. Add sorbic acid into the reactor, then add 66% water of sorbic acid mass, drop 49% of potassium hydroxide solution at 45℃, until Ph of the reaction solution is 8, the reaction takes about 45min.Add a certain amount of activated carbon, vacuum filtration, the filtrate at 40 ~ 45℃ reduced pressure evaporation for 3 ~ 4h to meet the requirements, then temperature to 70℃ feeding.The crystallization was obtained by centrifugal dehydration and the mother liquor was recovered.Finally, the product was dried at 105℃.

2. It is prepared by neutralizing sorbic acid with potassium hydroxide or potassium carbonate by dehydration and drying.
