Potassium sorbate destroys most of the action of the microbial enzyme system by binding to the sulfhydryl group of the microbial enzyme system. As an acid preservative, with pH below 5-6, it can effectively inhibit the activity of mold and yeast, and can also prevent the growth and reproduction of harmful microorganisms such as botulinum and staphylococcus.
Alcoholic foods, soda beverages, fresh orange juice, hawthorn juice and other beverages, and other non-alcoholic beverages can be added in proportion to sorbic acid to prolong the shelf life.
Such as soy sauce, sauce products, pickled vegetables, kimchi, etc., adding an appropriate concentration of sorbic acid solution can prevent the problem of mildew growth and deterioration.

Apples: The preservative liquid is sprayed on the surface of the apples and stored at room temperature for 4 months before deterioration occurs.
Canned vegetables: can prevent tinplate from rusting.
Sorbic acid can be directly added to flour or dough. When using, potassium sorbate should be dissolved in water or milk first, and then added to flour or dough.
