The role of potassium sorbate

Potassium sorbate can effectively inhibit the growth and multiplication of harmful microorganisms such as molds, yeasts, and oxygenic bacteria, Staphylococcus aureus, and Salmonella, but is ineffective against usefuluseful microorganisms such as anaerobic bacilli and Lactobacillus acidophilus, almost stronger against development than against sterilization, effectively prolonging the shelf life of food and preserving its original flavor
