摘  要：
为探讨壳聚糖协同次氯酸盐对北碚447锦橙贮藏品质的影响,用壳聚糖、壳聚糖协同次氯酸钠、壳聚糖协同次氯酸钙涂膜处理北碚447锦橙,每5 d测定1次果实贮藏期间果肉中可溶性固形物、总糖、总酸质量分数和VC、总黄酮、总酚含量等品质指标。结果表明:壳聚糖具有良好的果品品质保持作用,能较好地保持果实VC、总酚含量以及总糖质量分数;同时,壳聚糖与次氯酸盐协同涂膜对北碚447锦橙品质保持作用明显优于单独使用壳聚糖,其中0.01 g/m L壳聚糖+200 mg/L Ca(Cl O)2处理效果最显著,有效地延缓了贮藏期间果实品质的下降。说明壳聚糖协同次氯酸钙能够有效提高北碚447锦橙的贮藏品质和延长其贮藏期。

摘  要：
In order to investigate the effect of chitosan combined with hypochlorite on the storage quality of citrus fruits(the Beibei 447 cultivar of Citrus sinensis L. Osbeck cv. Jincheng), we used chitosan alone and in combination with either sodium hypochlorite or calcium hypochlorite to coat the fruits, respectively. Then, the contents of soluble solids, total sugar, total acid, VC, total flavonoids and total phenolics were analyzed every five days during storage. It was found that chitosan was good for maintaining fruit quality and the treated fruits maintained high contents of VC, total phenols and total sugar during storage. In addition, chitosan combined with hypochlorite coating was significantly more effective than chitosan alone and the best effect was obtained using 0.01 g/m L chitosan + 200 mg/L Ca(Cl O)2, effectively delaying the deterioration process. The results of this study suggest that chitosan combined with hypochlorite has the potential to maintain the quality and extend the post-harvest storage life of Beibei 447 sweet orange.
