Potassium Sorbate

According to Livestrong.com:

“Potassium sorbate is salt of sorbic acid and is prepared by reacting sorbic acid with potassium hydroxide. It is a white or yellowish crystalline powder or granule. Potassium sorbate is soluble in water. Once dissolved in water, it produces sorbic acid. It is effective as a preservative up to a pH of 6.5. Its effectiveness falls off as pH is lowered. It is inexpensive to produce, shelf stable and easy to use as an ingredient in foods and other products requiring antimicrobial activity.”

Potassium Sorbate comes from wood ashes and naturally occurs in berries, however, the Potassium Sorbate used in today’s manufacturing is chemically made.  While Potassium Sorbate can be a skin irritant, the molds that can develop on foods that don’t have it can also threaten health.
