中文摘要:探讨了棓酸丙酯处理对采后龙眼果实保鲜效应的影响。采后龙眼果实用浓度为5 mmol/L的棓酸丙酯浸泡20 min,以蒸馏水处理的果实为对照,果实晾干后用0.015 mm厚的聚乙烯薄膜袋密封包装,在(15±1)℃下贮藏。贮藏期间测定果实采后生理、品质和保鲜效果等指标的变化。结果表明:与对照果实相比,棓酸丙酯处理可有效降低龙眼果实呼吸强度,延缓果皮细胞膜相对渗透率升高,保持较高的果肉总糖、蔗糖、维生素C等营养成分含量和果皮叶绿素、类胡萝卜素、类黄酮和总酚含量,降低龙眼果皮褐变指数和果肉自溶指数,提高果实好果率。在(15±1)℃下贮藏6 d时,棓酸丙酯处理的龙眼果实好果率为85%,而对照果实只有72%。因此认为,浓度为5 mmol/L的棓酸丙酯浸泡20 min可有效延缓采后龙眼果实衰老、提高龙眼果实贮藏品质和保鲜效果。

Abstract:Effects of proply gallate treatment on freshness of harvested longan (Dimocarpus longan Lour.)fruits were investigated. The harvested longan fruits were dipped in 5 mmol/L proply gallate for 20 min, while, the control fruits were dipped in distilled water. The fruits were dried prior to packaging and stored at (15±1)℃. During fruit storage, the changes of postharvest physiology, quality and fresh-keeping effect of harvested longan fruits were determined. The results showed that compared with the control fruits, the treatments with proply gallate could effectively reduce fruit respiration rate, delay the increase of cell membrane relative leakage rate in pericarp, keep higher contents of pulp nutritional ingredients such as total sugars, sucrose and vitamin C, and higher contents of chlorophyll, carotenoid, flavonoid and total phenolics in pericarp, decrease pericarp browning index and aril breakdown index, and keep higher healthy fruit percentage. After 6 d storage at(15±1)℃, there were 85% healthy fruit in proply gallate treated longan fruits, while only 72% healthy fruit in the control fruits. From the results it can be concluded that the treatment of 5 mmol/L proply gallate dipping for 20min can effectively delay fruit senescence, increase fruit quality and fresh-keeping effect of harvested longan fruits. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
