Potassium Sorbate-E202 s physical properties:

E202-24634-61-5 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% E202-590-00-1 solution of PH7 ~ 8.

Potassium Sorbate-E202s use of:

Currently E202-590-00-1 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 . E202 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.

E202 corrosion resistance
E202-590-00-1 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,24634 -61-5 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. 24634-61-5 preservative effect is of similar products is 5-10 times sodium benzoate.
E202 security
Because E202-590-00-1 is an unsaturated fatty acid (salt) which can be absorbed by the bodys metabolic system and quickly broken down into carbon dioxide and water, E202 is no residue in the body.
E202 stability
E202-590-00-1 is stable in a sealed state, exposure to moist air, easy to absorb, E202-590-00-1 oxidation and discoloration. E202-24634-61-5 on the thermal stability is good, the decomposition temperature of up to 270 ℃.
