High Molecular Weight Good Price Bulk Chitosan Powder
Oligosaccharide Water Soluble Chitosan Powder
Description
Chitosan is in powder state, tasteless and odorless, and the aqueous
solution is somewhat pungent. Chitosan was added to food, and the
structure was not changed after boiling, frying, and baking to a
certain extent. Under the protection of nitrogen, it will not
decompose when heated to 250°C. The chitosan powder was stored for
181 d in a natural environment away from Chemicalbook sunlight at
room temperature, and there was no obvious change in appearance,
solubility, and degree of deacylation. The biscuits added with
chitosan were stored in an environment with a temperature of 40 °C
and a relative humidity of 75% for 80 days in the packaged state,
and the content of dietary fiber and chitosan in the samples did
not change.

Application Field
1.Sewage treatment: Chitosan can treat suspended substances in sewage, adsorb certain
heavy metal ions, etc., reduce BOD and COD of sewage, and chitosan
can also be used in surface water treatment.
2.Petroleum Auxiliary: According to the characteristics of chitosan's macromolecule
properties and amino positive charge, chitosan can also be used in
the fields of petroleum exploitation and shale gas exploitation
assistants.
3.Paper making: Special types of chitosan can be used as sizing agent, reinforcing
agent, retention aid, etc. in paper making to increase paper
strength and recover lost pulp.
4.Agriculture: Chitosan can be used in seed soaking, coating agent, foliar spray
fertilizer, bacteriostatic agent, soil conditioner, feed additive,
fruit and vegetable preservative, etc.
5.Chitosan is also widely used in other fields.
