Sorbic Acid, E200, CAS no.110-44-1, food preservative, manufacturing process via chemical synthesis, malonic acid and trans-butenal as raw materials, also can be produced from isomeric hexadecenoic acids. Sorbic acid is used in it's salt forms (sodium sorbate, Potassium sorbate, and calcium sorbate) as a preservative in the production of drinks and food to prevent the growth of any mold, yeast, and fungi. It can be used to preserve wines, beverages, soy sauces, picked products, seafood, and meat products. The preservative efficiency of Sorbic Acid is 5-10 times the effectiveness of Sodium benzoate. As an experienced Sorbic Acid manufacturer and supplier, we has been supplying and exporting Sorbic Acid for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.
