company cooperated with the Chinese Academy of Science Institute
of Oceanography in researching and developing this new product in
2002.The product and technology fill up the civil gap.
composed of β-(1-4)-linked glucosamine.
the oligosaccharides with
the degree of polymerization ranging from 2 to 20 and moleclar
weight lower than 4000 is named Chitosan Oligosaccharides。
Chitosan Oligosaccharides is easy to be absorbed，having
the functions of enhancing immunity of the body and inhibiting
proliferationg of cancer cell。The
body activates own immnune system to stop cancer cell transfering
by promoting the activities of macrophage-lysyme and NK，which
has selective destrucion on cancer cells. it can strengthen the
fuctions of liver, promoting the spleen to produce antibody, not
only adsorbing and decreasing damage of toxicant but also
revivifying the damaged liver cellers and restituting
It can improve fuctions of
alimentary canal after it changed into gel in stomach juice which
has good bonding strength and is hardly separated from atratum
mucosum. The gel becomes efficient protective film to diminish
attack of hydrochloric acid in gastric juice .
Chitosan Oligosaccharides can promote intestinal peristalsis to
avoid constipation and accelerate body’s absorbilities of Ca2+ and
Chitosan Oligosaccharides can treat spoiled skin .because of the
anti-bacteria, it’s usually made
protective materials in curing burn, scald and ulcer, with ggo
affinity and absorbility of exudate. So it can promote new cells
growing and epithelial cells forming, with little scar as possible.
can improve humoral environment.
Chitosan Oligosaccharides, which is the only positively charged
polysaccharide, can keep the body fluid in hedlthy weakly alkaline
incidence of disence.
It also can lower hyperlipemia,
adjust the absorbability of cholesterol inside the
scavenge oxygen radical in body,
remove harmful substances and
activate cell, postpone senility.
The product (Chitosan Oligosaccharides) is manufactured by enzyme
degradation of the high-qualitative Chitosan Polysaccharides from
shrimps and crabs. It is the low-molecular-weight marine product
with good water-solubility, special biological activities, and
high biological activities. This product, with average degree of
polymerization of 10 and the mean molecular weight of 1500,
contains high level of the hexasacchride, heptose, octose and
nonasacchride, which have high biological activity. The absorbance
rate of the products reaches to nearly 100% and its biological
activity is more than ten times higher than that of Chitosan
It is called “softgold”
and applied widely in the
fields of medicine,
cosmetic and agriculture etc in
the advance counties such as Japan,
Europe and America.
is the high-technological product in the industry of chitosan and
has potential and profitable market.
