Sorbic acid (potassium) can effectively inhibit the activity of mold, yeast and aerobic bacteria, and can also prevent the growth and reproduction of harmful microorganisms such as botulinum, staphylococcus and salmonella, but it is not effective for anaerobic spores and acidophilus Beneficial microorganisms such as Lactobacillus are almost ineffective, and their growth inhibitory effect is stronger than bactericidal effect, so as to effectively prolong the storage time of food and maintain the original flavor of food
