In this paper, we presented the preservation effect of chitosan membrane, chitosan - gelatin - sodium alginate composite film which coated with fresh loquat fruit,and stored those loquat fruit packaging in polyethylene film at 6 + 0.5 ¡æ. Results show that preservation effect of chitosan gelatin - sodium alginate composite film coating treatment on loquat fruit is better, the physical and quality index of the loquat fruit was significantly higher than the chitosan film coating group, after storage 35 d, weightlessness rate of chitosan coating composite film below 0.8% to tosan film coating,and good fruit higher 9.83%; Thougt peroxidase activity in the loquat fruit is rising trend In the early storage using chitosan coating composite film , but after 28 d it began falling rapidly, to end reduced 150.1 U ¡¤ g - 1 comparing at first storage. The research was conducted with preservation effect of hitosan gelatin- sodium alginate composite membrane for the loquat fruit is best. |
