摘要
在一定范围内，龙眼果肉细胞透性越低，总糖、还原糖与可溶性固形物含量越高，果实品质风味越好。试验采取九成熟福眼果实测定其乙烯释放量只有２．３１－３．９１ｎｌ·ｇ^(-１)·ｈ^(-１)，乙烯作用不明显，不是果实主要衰老激素。果实采后没有明显呼吸高峰，不具跃变型水果典型特征，所以不适于气调贮藏，较适于冷藏。福眼果实采后用绿色Ⅰ和绿色Ⅱ保鲜剂洗果、ＥＶＡ薄膜袋包装，效果最佳；３０±２℃贮藏８ｄ好果率９６．６％，３－４℃贮藏４５ｄ好果率９８．８％；在－１８℃速冻贮藏１８３ｄ和３６６ｄ，好果率分别为９９．５％和９８．０％。
Within certain period of storage,the contents of total sugar,reducing sugars and total soluble solids ofLongan fruits increased, with the decrease of the permeability of the pulp cells, and the flavor was improved。The ethylene production of Fuyan longan was only 2.31-3.91 nl·g￣(-1)·h￣(-1) during storage。No significanteffect of ethylene on the senesence of the fruit was noted.No climateric peak was observed in respiration,sothat,the longan fruit was preferred to be stored in cold storage rather than CA storage.Treatments withGreen Ⅰand Green Ⅱand packed with EVA film bags gave the best result.The rates of marketable Fuyanlongan fruits were 96.6%after 8 days' storage at 30±2℃;and 98.8%after 45 days' storage at 3-4℃;and99.5%and 98.0%after 183 and 366 days,storage quick frozened storage at-18℃.
