【摘要】 用可食性魔芋葡甘聚糖膜对“乌龙岭”龙眼进行处理后，分别置于常温（２９～３１℃）和低温（３℃）下保鲜，并着重研究了其保鲜效果。试验表明：常温保鲜１０天后龙眼的好果率达８２．８６％，失重率为２．５６％；低温保鲜６０天后龙眼的好果率达８８．８９％，失重率为２．０３％。两者的祸变率均低于对照组，基本上防止了果皮失水、褐变，果肉长霉、腐烂变质，保持龙眼原有风味，延长了贮藏期和货架寿命。更多还原

【Abstract】 After longan fruits (Dimocarpus Longana Lour.cv.Wu tong Ling)were treated with edible konjac glucomanan film.Each of them was kept fresh at room temperature (29-31℃)and low temperature (3 ℃),and emphasisly studied its storing effect.The results showed the healthy fruit rate was 82.86%,loss rate was 2.56% for 10 days at room temperature;the healthy fruit rate(88.89%),loss rate(2.03%)were, obviously better than of oh.The method basically inhibited the pericarp browning with the pulp mold growing,badening and decaying, kept fruits with fine flavour,and prolonged the storage life and shelflife.更多还原
