中文摘要: 以三华李果实为试材，通过测定不同浓度富氢水(hydrogen water，HRW）处理及纳米TiO2-壳聚糖复合涂膜下三华李果实的好果率、单果重、硬度、可溶性固形物含量、可溶性蛋白含量以及果实品质质量等指标，研究富氢水和纳米TiO2-壳聚糖复合涂膜对三华李的保鲜作用，以期筛选出有效的保鲜方法。结果表明：相对于对照组（0%HRW），25%、50%、75%、100%HWR处理均能在一定程度上延长三华李的贮藏期，其中50%HRW处理效果最为显著。纳米TiO2-壳聚糖复合涂膜处理组与对照组相比，提高了三华李的耐储性。进一步比较50%HRW处理和纳米TiO2-壳聚糖复合涂膜的保鲜效果，得出50%HRW处理较纳米TiO2-壳聚糖复合涂膜贮藏时间延长，有利于延长三华李的货架期。

Abstract:The preservation effects of hydrogen water（HRW）of different concentrations and nano-TiO2-chitosan composite coating were investigated by measuring the indicators，such as good fruit rate，single fruit weight，hardness，soluble solid content，soluble protein content，and fruit quality of Sanhua plum fruit to screen out an effective fresh-preserving method.The results showed that compared with the 0%HRW treatment in the control group，treatments of 25%HRW，50%HRW，75%HRW，and 100%HRW could prolong the storage period of Sanhua plum to a certain extent，and 50%HRW treatment had the most significant effect.Compared with the results in the control group，the storage resistance of Sanhua plum was improved in the nano-TiO2-chitosan composite coating group.The comparison of the fresh-preserving effects of 50%HRW treatment and nano-TiO2-chitosan composite coating suggested that 50%HRW treatment could result in longer storage time than the composite coating，which was an effective fresh-preserving method beneficial to prolonging the shelf life of Sanhua plum.
