Product Name: Chitosan
Deacetylation* Degree: >85%, 90%, 95%
CAS No.: 9012-76-4
Molecular Formula: (C6H11NO4)n
Struction:
We have advanced technology and high quality products.
Off-white, innocuous, flavourless semitransparent and
amorphous solid. Soluble in acid, but insoluble in alkali and
water or in ordinary organic solvent. Decomposed at
185°C.
Applications:
1.Food Field
Used as food additives, thickeners, preservatives fruits and
vegetables, fruit juice clarifying agent, forming agent,
adsorbent, and health food.
2. Medicine, health care products field
As the chitosan non-toxic,has anti-bacterial,
anti-inflammatory, hemostatic, and immune function, can be used
as artificial skin, self-absorption of surgical sutures,
medical dressing Branch, bone, tissue engineering scaffolds,
enhance liver function, improve digestive function, blood fat,
lowering blood sugar, inhibiting tumor metastasis, and
adsorption and complexation of heavy metals and can be
excreted, and so on, was vigorously applied to health food and
drug additives.
3. Environmental protection field
Chitosan and its derivatives is a good flocculant for
wastewater treatment and metal recovery from metal-containing
waste water; in textile field: as a mordant, health care
fabric, sizing agents, printing and dyeing.
4.Agricultural field
As growth promoters, bio-pesticides, feed additives, seeds,
etc.
5.Field of tobacco
Tobacco sheet used as adhesives, low-tar filter and so
on.
FOOD-GRADE CHITOSAN CERTIFICATE OF
ANALYSIS
(1)We can supply high-purity chitosan with deacetylation degree
>95%.
(2)The viscosity is determined at 20°C with 1°C chitosan in 1°C
acetic acid.
The different applications of chitosan demand different type of
chitosan, We can supply it according to the needs.
We can provide special molecular weight Chi Chitosan
(20,000-300,000) and Chitosan Oligosaccharide
(1,000-8,000).
