Potassium sorbate is a weak organic acid that penetrates microorganisms' cell membranes. Inside the cell, it dissociates into sorbate ions, which lowers the cytoplasm's pH. This disrupts ion balance and causes sorbic acid to accumulate in the cell, damaging the membrane and cellular proteins and ultimately leading to the microorganism's demise. Disrupting cellular membranes also hinders nutrient uptake and waste product release, further hindering microorganism growth. Overall, potassium sorbate's mechanism of action hinges on its ability to penetrate cell membranes and disrupt ion balance, resulting in cellular damage and growth inhibition.
Combining sorbic acid and potassium hydroxide will formation potassium sorbate. One can create sorbic acid through a chemical process using crotonaldehyde and malonic acid or extract it from natural sources such as rowan berries and mountain ash berries.
