Excellent preservative properites:properites:
Sorbic Acid( Potassium Sorbate) can restrain effectively the activity of mould, yeast and aerophile bateria. Restrain growth and reproduction of the pernicious micro organism as pseudomonas, staphylococcus salmonella action to restrain growth is more powerful than killing. Meanwhile, it can not restrain useful microoranganim growth ad Anaerobic-bearing barilli, acidophil therefore to lengthen food store peroid and remain food original flavor. The preservative efficiency of sorbic acid(Potassium sorbate) is 5-10 times sodium benzoate.
High safety:
Sorbic Acid( Potassium Sorbate) is one kind of nonsuturated fatty acid compounds. It can be absorbed by human body rapidly, then decomposed into CO2 and H2O,moreover no remaining in body. ADI 0-25mg/kg (based on sorbic acid FAO/WHO 1994) LD50 4920 mg/kg(large mouse by mouth) GRAS(FDA, 182.3640 1994) Its toxicity only 1/12 times table salts and 1/40 times sodium benzoate.
Good stability:
Sorbic Acid( Potassium Sorbate) is stable in sealed staus, will not be decomposed until 270°C. It will be oxidized into colored ones and absorbing moisture in case exposed in air for a long time.
Wide application:
At the moment,Sorbic Acid( Potassium Sorbate) has been used extensively in food, drink,vegetables in soy, tabacco, drugs, cosmetics, agricultural products, forage and other domain. Its applicaion should be wide and wide in the world.
As acidic preservative, Sorbic Acid( Potassium Sorbate) is also used well in neutral food(ph6.0-6.5). The preservative efficiency of sodium benzoate will decrease clearly and have a bed taste while ph>4
Applicaion flexibility:
Sorbic Acid( Potassium Sorbate) can be used by direct adding, spraying,retting, dry spraying , using in packing material and other method.

We normally list 24 months as the shelf life in our COA, the real shelf life can be slightly longer than 24 months if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials), but it's still suggested to avoid long time storage
