摘要
研究了采用1.0%、1.4%和1.6%浓度的壳聚糖涂膜处理武隆猪腰枣后,在1℃,相对湿度90%的条件下的保鲜效果。结果表明:1.4%壳聚糖涂膜处理有效地延缓了武隆猪腰枣果实硬度、Vc及可溶性固形物含量的下降,在贮藏末期(60d)时,各检测指标均明显优于对照组,并有效地抑制了细菌和降低了烂果率,较好地保持了猪腰枣贮存期的品质。
As a local fresh jujube species in Chongqing, Wulong loin jujube has high nutritional value and excellent flavor. But the storage period of Wulong loin jujube was very short, and this was the reason why its industry development was hindered the development. In this study, fresh Wulong loin jujubes were coated with chitosan at differ- ent concentrations （1.0%, 1.4%, and 1.6%）, and then they were stored at （1 ± 0.5）℃ with 90% relative humidity to examine the preservation effects of chitosan coating. The results showed that the dosages of 1.4% ehitosan coating could delay the reductions of firm- ness, and Vc and the contents of soluble solids. It was also found that the rot fruit rate was effectively reduced, and all the targets a hove were superior to CK group after stored for 60 days.
