HOMEPAGE 
 

 

 		     Potassium sorbate is the potassium salt of sorbic acid. Both potassium  
sorbate and sorbic acid are novel ,highly efficient, safe and nonpoisonous  
food  preservatives recognized internationally as a best series. It is the  
substitute for the sodium benzoate as a traditional preservative. 
     
   In contrast to sorbic acid , potassium sorbate is more convenient for  
use because of its higher solubility in water . 
     
    Potassium sorbate has obvious inhibitive effect for mould, yeast and  
aerobion. Being an acidic preservative it is better to use under PH5~6. 
molecules of potnssium sorbate can combine with hydrosulfide group of  
microbiological's enzymatic system to destroy its activity . 
     
    Potassium sorbate is the potassium salt of an unsuturated fatty acid,  
which participates in the normal fat metabolism in human body and will  
be oxidated into carbon dioxide and water finally .It will not be accumu- 
lated in human body . 
    
   Beside the role of food preservative, potassium sorbate is also  widely 
applied in the industries of medicine, daily cosmetics, papermaking,feed  
additive and tobacco etc.
