中文摘要: 用茶多酚对石硖龙眼进行处理,对其贮藏期间的各种与保鲜有关的表形和营养指标进行了测定。结果表明,不同浓度的茶多酚溶液均可提高龙眼果实贮藏期间的好果率、减缓果实失重、提高贮藏期间尤其贮藏后期果肉可溶性固形物的含量、延缓可滴定酸含量的变化,对龙眼果实在贮藏期间的总糖和VC的变化均产生良好的影响。与对照相比,经茶多酚溶液处理后,可滴定酸含量提高70%,还原糖含量提高16.49%,总糖含量提高29%,VC含量提高49.58%。
Abstract:The effects oftea polyphenols on longan fruits offresh-keeping during storage were tested.The flavor and nutritional indexes were determined.The results showed that various concentrations of TPs could protect longan fruits from decay and improve the nutrientsubstances such as VC,titratable acid,sugar etc.during storage.Compared with the control,contents oftitratable acid increased 70%,contents ofreducing sugar increased 16.49%,contents oftotalsugar increased 29%,and contents of VCincreased 49.58%.
