Sorbic Acid, or 2,4-hexadienoic acid, is a natural organic compound used as a food preservative. The chemical formula is C6H8O2. It is a colourless solid that is slightly soluble in water and sublimes readily. It was first isolated from the unripe berries of the rowan tree (Sorbus aucuparia), hence its name.
As colorless acicular crystal or white crystalline powder, Sorbic Acidis soluble in water and can be used asPreservatives. Sorbic Acid can be widely used as food ingredient or food additive in our daily life. Sorbic Acid is mainly used in food, beverages, tobacco, pesticides, cosmetics and other industries. As an unsaturated acid, it also can be used in resins, spices and rubber industry.

2. Sorbic acid and potassium sorbate are the most widely used preservatives in the world. They have high antibacterial properties, inhibit the growth and reproduction of molds, inhibit the growth of microorganisms and prevent corrosion by inhibiting the dehydrogenase system in microorganisms. It has an inhibitory effect on mold, yeast and many good bacteria, but it is almost ineffective against anaerobic spore forming bacteria and Lactobacillus acidophilus. It is widely used in the preservation of foods such as cheese, yoghurt and other cheese products, bread snack products, beverages, juices, jams, pickles and fish products.
