摘要: 以天草果实为材料,通过正交试验确定涂膜处理的最佳条件。本研究对天草果肉中的含水量、还原糖、总酸、VC以及果皮中的SOD活性、POD活性和相对膜透性进行了测定。结果表明:营养物质整体呈下降趋势,而涂膜处理的营养成分高于对照;果皮中的SOD活性比对照要高,而相对膜透性减小。涂膜保鲜贮藏可以延缓果实衰老,具有较好的贮藏效果。

Abstract: The optimum condition of chitosan-coating treatment was determined through orthogonal test, with citrus Tian-cao as material. In the study the changes of water content,deoxidizing sugar, total scid, VC in the pulp, SOD activity, POD activity, membrane permeability in the peel of Citrus Tian-cao during storage were determined. The results showed that nutrition component is always in a tendency to decrease, also fresh-keeping coated by chitosan is higher than control, SOD activity increases and relatival membrane permeability of peel is lower than control in the whole storage time. Therefore, citrus Tian-cao fresh-keeping by chitosan can delay senescence of fruit so that it has better effect.
