Food Grade Chitosan For Keeping Fruit And Vegetable Fresh
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.
Chitosan is insoluble in water or alkali solution,but it is soluble
in many kind of organic acid and part inorganic acid
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
