2. Introduction
As a higheffective preservative recommended by FAO and WHO,potassium sorb ate can inhibit the activity
of fungus,yeast and aerobic bacterium,and prevent the growth,reproduction of botulinum,staphylococcus,
salmonella and other harmful microorganisms. Moreover,Potassium Sorbatev has no effect to beneficial microorganisms,such as anaerobic bacillus and acidophilus lactobacillus.Having a stronger inhibition effect thansterilization effect,Potassium Sorbate can effectively prolong the preservation time of the food without changing the original flavor.The antisepsis effect of Potassium Sorbate is 5-10 time as much as that of sodium

3. Applications
1). It is mainly used to inhibit the growing of microbe in food.
2). In the daily living,it can be used to prevent the mildew for soy,wine,edible vinegar and salted
vegetables.Only adding 0.1 percent into them, you will find that their taste is better.
3). In freezing and cold storing foods, especially fish and shrimp, soaking them in the solution of potassiuM sorbate(0.3%) for 30 seconds, they can keep their original and individual taste.
4). Adding potassium sorbate to man-made cream and salad oil can prevent sourness and bubble because of fermenting.
5). If you add potassium sorbate into pastry, biscuit and bread, they will be of better tasty!
6). The meat which added the potassium sorbate can be store more a week than before.
