| 摘 要： | 为探究魔芋葡甘露聚糖-壳聚糖复合涂膜对北碚447锦橙贮藏品质的影响,分别采用0.5%魔芋葡甘露聚糖+1%壳聚糖复合涂膜,0.5%魔芋葡甘露聚糖涂膜和空白处理北碚447锦橙。以5 d为一个周期,15 ℃温度贮藏,共贮藏5个周期,测定贮藏期间果实的总糖、可滴定酸、VC、固形物、总酚等指标。结果表明,复合涂膜处理可有效延缓果实品质的下降,与0.5%魔芋葡甘露聚糖涂膜和空白处理对比,复合膜组能够明显抑制果实总糖、可滴定酸、VC、总黄酮、总酚含量的下降,减缓果实中丙二醛的积累,使锦橙保持了较好的果实品质。证明了复合涂膜处理相比单独0.5%KGM保鲜效果更好。

| Abstract: | The storage quality of konjac glucomannan combined chitosan coating on citrus(C. sinensis L. Osbeck cv. Jinchengbeibei 447)was studied in this paper. The citrus were treated with 0.5% konjac glucan-mannan+1% chitosan,and 0.5% konjac glucanmannan. Total sugar,titratable acidity,VC,soluble solids,total phenolics,total flavonoids,MDA were taken as the index to evaluate the quality of the citrus during storage. The results showed that,the citrus coated with liquid could keep a good quality,and the citrus coated with 0.5% konjac glucanmannan+1% chitosan could significantly inhibit the decrease content of total sugar,titratable acidity,VC,soluble solids,total phenolics and total flavonoids. It could also significantly inhibit the increase of MDA. It was proved that 0.5% konjac glucanmannan+1% chitosan was better than 0.5% konjac glucanmannan in fresh-keeping. |
