APPLICATIONS

Sorbic Acid (also called chemically 2,4-hexadienoic acid ), a white crystalline powder or granule form  for dust free, is an unsaturated fatty acid which has two double bonds in conjugation that is, two double bonds separated only by one single bond. It and its salts (potassium sorbate, calcium sorbate ; its salts are used according to differences in solubility.) are used as preservatives in wide range of food products as well as in their packaging materials, since they are characterized by their broad effectiveness to inhibit molds, yeast, and many bacteria growth in food. Potassium sorbatem, white to slightly yellow crystalline powder, is the potassium salt of sorbic acid and is much more soluble in water than the acid. Potassium sorbate will releases back sorbic acid if dissolved in water. It is effective up to pH 6.5 but effectiveness increases as the pH decreases. The lower the pH value of the product the lower amount of Sorbic Acid or Potassium Sorbate is needed for preservation. Its industrial applications include use in coating industry to improve gloss and in rubber industry. Sorbic acid and its derivatives are used as a a mold, bacterial and yeast inhibitor and as a fungistatic agent in foods. It is also used in cosmetics, pharmaceutical, tobacco and flavoring products. They are used in coating to improve gloss and as intermediates to manufacture plasticizers and lubricants. They are used as an additive in rubber industry to improve milling characteristics.
