Potassium Sorbates physical properties:
Potassium Sorbates as a white to light yellow flake-like crystals, crystal grains or crystalline powder, odorless or slight odor, E202-term exposure to air, easy to absorb moisture, oxidation decomposition and discoloration. E202 soluble in water, 67.6g/100ml (20 ℃); 5% salt water, 47.5g/100ml (room temperature); 25% sugar, 51g/100ml (room temperature). Dissolved in propylene glycol, 5.8g/100ml; ethanol, 0.3g/100ml. 1% Potassium Sorbates solution of PH7 ~ 8.
Potassium Sorbates use of:
Currently Potassium Sorbates has been widely used in food, beverages, pickles, tobacco, pharmaceuticals, cosmetics, agricultural products, feed and other industries, the development trend, E202-590-00-1 is still expanding range of applications . Potassium Sorbates preservatives are acidic, near neutral (PH6.0-6.5) the food is still a good antiseptic, and benzoic acid (sodium) and anti-corrosion effect in PH> 4, the effect has decreased significantly, and there bad taste.
Potassium Sorbates corrosion resistance
Potassium Sorbates can effectively inhibit mold, yeast and aerobic bacteria activity, but also to prevent botulism, staphylococcus, salmonella and other harmful micro-organisms grow and reproduce, but the anaerobic bacteria and Bacillus Lactobacillus acidophilus and other beneficial microorganisms almost ineffective, Potassium Sorbates restrain the development of a stronger role than sterilization, so as to achieve effectively extend the shelf life of food, and keep the original flavor of food. Potassium Sorbates preservative effect is of similar products is 5-10 times sodium benzoate.
