What Are The Effects And Uses Of Chitosan Powder?

 

Chitosan powder is the product of chitin after deacetylation. Its chemical name is β-(1→4)-2-amino-2-deoxy-D-glucan. It is water-soluble when the degree of deacetylation (DD) is ≥55%. Its molecular weight ranges from 20-1000 kDa, and its crystallinity is 75%. It is the only alkaline polysaccharide with positive charge in nature.

 

2. Chitosan source

• Marine organisms: shrimp and crab shells (global annual production is 2 million tons, China accounts for 65%).
• New extraction: fungal cell walls (such as Aspergillus niger) and insect exoskeletons (silkworm pupae, locusts).

 

2. Functional properties

• Biological adhesion: electrostatic binding time with mucosa is greater than 8 hours.
• pH responsiveness: dissolution rate is greater than 90% in gastric acid environment (pH 1.2), and gel is formed in the intestine (pH 6.8).
• Chelating ability: 600mg heavy metal ions (such as Pb²⁺, Cd²⁺) can be bound per gram.

 

 

1. Biomedical field

(1) Wound repair system

• Activates macrophage M2 polarization, speeding up wound healing by 40%.
• Promotes type III collagen deposition.

 

(2) Precision drug delivery

• Targeted carrier: Folic acid-modified pure chitosan powder nanoparticles have a liver cancer targeting efficiency of 89%.
• Controlled release technology: Oral insulin formulations achieve 12-hour stable glucose control.

 

(3) Metabolic regulation

It can combine with dietary fat to inhibit pancreatic lipase activity

 

2. Environmental and industrial applications

 

(1) Wastewater treatment

• The efficiency of removing microplastics is 94%.
• The removal rate of heavy metals in industrial wastewater, such as Cr⁶⁺, is 99.8%.

 

(2) Food preservation technology

• Antibacterial film inhibits the formation of Escherichia coli biofilm.
• The shelf life of strawberries is extended to 21 days.

 

(3) Agricultural efficiency enhancement

• Chitosan-selenium nanofertilizer increases the selenium content of rice by 8 times.
• Induce plant disease resistance genes.

 

 

1. Allergy risk

• The cross-reaction rate of people allergic to crustaceans is 18.7%.
• Symptoms: urticaria (incidence 3.2%), respiratory edema (0.7%).

 

2. Nutritional interference

• Binding fat-soluble vitamins, vitamin A absorption rate decreased by 29%.
• Chelating essential minerals such as iron and zinc, serum ferritin decreased by 15%.

 

3. Digestive tract reactions

• High doses (>5g/day) cause abdominal distension and constipation.
• Chitosan powder bulk should be used with caution in patients with irritable bowel syndrome.

 

4. Contraindications for special populations

• Pregnant women: may affect placental angiogenesis.
• Immunosuppressed patients: activation of the TLR4 pathway potentially interferes with immunotherapy.
