【Product Introductions Of Natural Preservative Water Soluble Chitosan Oligomer 】

 

Microbial breeding and oxidative deterioration are the main factors affecting the shelf life of food. Food preservative technology has made a certain breakthrough under the action of chemical preservatives. However, with the increase of consumer demand, consumers prefer food without chemical preservatives. Therefore, natural preservatives have attracted people's attention.

 

Chitosan oligosaccharide can effectively lock water molecules, and the polar groups in the molecules can interact with water molecules to affect the activity and flow resistance of water. Therefore, chitosan oligosaccharide has good moisture absorption and moisture retention, remarkable antibacterial effect and outstanding oxidation resistance. It also inhibits respiration and improves the defense mechanism of fruits and vegetables. It is a natural food preservative with excellent performance.

【Mechanism Of Natural Preservative Water Soluble Chitosan Oligomer  】

 

Chitosan has good colloidal properties and film-forming properties (it is easy to dissolve in acidic aqueous solution to form high viscosity colloidal solution, and a transparent chitosan film can be formed on the surface of fruits and vegetables), reduce its exchange with external substances and gases, and has micro air regulation function, form a low O2 and high CO2 environment, better reduce the respiratory intensity of fruits, and prevent water evaporation.

 

Chitosan oligosaccharide can more effectively protect the cell membrane structure and reduce membrane lipid peroxidation. The decomposition rate of nutrients is obviously slow, which is due to the good scavenging ability of reactive oxygen species.
