银杏叶粗提物对荔枝的防腐保鲜效果
Effects of leaf crude extracts from Gingo biIoba L.on the preservation of litchi
摘要
Abstract
The leaf crude extracts were obtained from Gingo biloba L. using ethanol extraction method,and its preservation on litchi was studied on the aspects of color,VCcontent,weight loss rate,the to-tal number of bacteria and sensory evaluation.The results showed that leaf crude extract of ginkgo biloba could reduce the loss of water,inhibit the browning,reduce the decrease of VCcontent,the infection of litchi flesh and the decay rate of litchi,and keep the sen-sory quality of litchi.Its ability of antibacterial effects and preserva-tion was followed by 0.6% leaf crude extract of ginkgo biloba>0.4% leaf crude extract of ginkgo biloba>0.2% leaf crude extract of ginkgo biloba>control.It indicated that the positive correlation was found between the preservation effect on litchi and the concentration of crude extract of ginkgo biloba leaves within a certain range.Theere-fore,it was found that the leaf crude extract of ginkgo biloba had better preservation effect on litchi.关键词
