Abstract

In this paper, pullulan, gelatin and chitosan were used as film-forming materials. Through the orthogonal experiment, oxygen transmission rate and water vapor transmission rate of the composite film of nine ratios were measured, and the best ratio of these three components was obtained. In 100mL 1% acetic acid solution, the best formula of the composite membrane is pullulan 2.5g, gelatin 1.5g and chitosan 1.25g. Finally, the composite coating liquid of the best ratio was compared with the one-component coating liquid, by measuring the decay index, rot rate, weightlessness rate and storage period of strawberries to reveal the effect of the composite coating fluid. The results show that the effect of preservation of composite membrane is better than that of the corresponding one-component membrane and PE.
