Study on Filming Character of Chitosan-Bamboo Vinegar
In order to investigate the filming character of chitosan dissolved in bamboo vinegar, the propertyof chitosan-bamboo blend solution was studied by using 4 times dilution bamboo vinegar as a solvent at differenttemperature and storage time. A solution of chitosan dissolved in 1% (v/v) acetic acid was made as acontrast. The filming effect was evaluated with the method of filming on a glass plate and on fruits surface.The results indicated that the relative viscosity of chitosan-bamboo solution increased along with the concentrationand reduced along with temperature increasing and time lasting. The transparency of the blend solutionhowever, the moisture permeability of the film increased along with increasing the glycerol dosage. Thechitosan-bamboo vinegar solution could be used for a packaging film material with concentration of 1% ~2%when used on the surface of fruits or 2.5% used as single film material. The appropriate condition of chitosan-bamboo vinegar solution for filming was by preparation at 40-50 with 0.25%(w/v) NaCl, ℃ , 2%(w/v)Twain-80 based on the solution or with 50%(w/w) glycerol based on the chitosan.
