Details

our company production of chitosan is divided into three levels: food grade and industrial grade/agriculture grade, pharmaceutical grade.the main basis of the three levels of the division is different of the degree of deacetylation, from low to high.more than 85% for agriculture grade or industrial grade, more than 90% for food grade, more than 95% for the medical level. for the different of the degree of deacetylation,lead to other indicators also corresponding changed.

chitosan is made from the deep-sea snow crab shells,unpolluted and safe character . it is the substance obtained by deacetylation of chitin .due to our chitosan is a natural drying, its color is more white than the chitosan which were produced in the traditional drying methods,and it has pearly luster.see the picture as follows.

oligosaccharide chitosan
oligosaccharide chitosan :
the oligosaccharide chitosan is a light yellow powder which was welcomed by the health food industry and agriculture.and it is solve in water.it can eliminate oxygen free radical, activation of the body cells, anti-aging, inhibiting harmful bacteria on the skin surface, and it has excellent moisturizing performance.the oligosaccharide chitosan is integrating with nutrition, health care, diet, so it is widely used in food, health food, beverage, medicine, feed additives and other fields.

high density chitosan
high density chitosan:
the high density chitosan is non-toxic, tasteless, white or light yellow powder and its density is >0.6 g/ml. its physical characteristics are similar to those of ordinary chitosan.high density chitosan gastric soluble time is short, can quickly dissolved in acid conditions, adsorption of fat and cholesterol.its oil adsorption ability is three times as many ordinary chitosan when the same volume.
