Water Soluble Pure Chitosan Powder for Food Supplements Application
We supply Water Soluble Pure Chitosan powder for food supplements production purposes. Normal chitosan is not soluble into water, in order to make it more easy for our customers to use, we change our production process and developed the water soluble chitosan powder.
Water soluble chitosan is able to be applied in more products than normal grade chitosan.

The advantage of our Water Soluble Chitosan Powder
1. Water soluble: Our chitosan is soluble into water, which will be more easier to be applied in food supplements production.
2. Good quality raw materials. Our chitosan is produced from the shells of unpolluted shrimp and crabs. The pure raw materials make the quality of our chitosan superior.
2. GMP Production: The water soluble Chitosan is produced in the GMP facility with GMP quality management system.
3. QC Laboratory. We have QC laboratory to test the materials before we release the materials to you.

There are many types of chitosan which is usually called Water soluble Chitosan, see below:
1. Chitosan soluble in water
2. Low molecular weight chitosan (or oligosaccharide) soluble in water
3. Chitin which is soluble in water
4. Carboxymethyl chitosan soluble in water
5. Hydrochloride-soluble chitosan hydrochloride
All of the above five substances can be called water-soluble chitosan, but only the first one is the true water-soluble chitosan (WSC). It is soluble in water, has a high molecular weight, and is a general chitosan, that is, only acetylglucosamine residues and glucosamine residues in the molecular chain, and the difference from ordinary chitosan is only the degree of deacetylation.
Packing: Our Water soluble Chitosan is sealed into Double PE bags, then was put into a fiber drum. One drum will contain about15KG chitosan powder. One pallet contains totally 27 drums with 9 drums one layer, total 3 layers.
