Food Grade Chitosan For Fresh - keeping In Fruit And Vegetable
1. Quick Detail :
Fresh-keeping chitosan has higher viscosity and suitable molecular weight,so it can form film on the surface of fruit and vegetable and this chitosan film can adjust and inhibit breath of fruit and vegetable.
In the other hand, fresh-keeping chitosan has good antibacterial properties.
2. Description :
Chitosan is extracted from deep-sea Alaskan Snow crab leg.
It is white or off-white amorphous translucent powder or small flake.

Scientific name: β-1,4-poly-D-glucosamine
Molecular formula : (C6H11NO4)n
CAS No. 9012-76-4
HS No. 2922 5000
3. Applications :
Chitosan film blocks transpiration of water and decreases loss of moisture.
Chitosan can prevent decrease of sugar and acid content during the storage period and even increase content of VC.
Chitosan can reduce activity of relevant enzyme during the storage period of fruits and vegetables, restrain generation of MDA and improve stability of cellular membrane.
Chitosan can improve SOD activity in fruits and vegetables, reduce damage of free radical to cellular membrane and postpone cell caducity.
Chitosan can induce a series of defensive reaction of fruit and vegetables, block attack of bacteria
