中文摘要:研究了(10±5) kPa和(80±5) kPa 2个不同减压压力处理及常规冷藏条件下水蜜桃贮藏期间能量相关物质三磷酸腺苷(ATP)、二磷酸腺苷(ADP)、磷酸腺苷(AMP)含量和能荷(EC)以及 H+-ATPase、Ca2+-ATPase、琥珀酸脱氢酶(SDH)、细胞色素氧化酶(CCO)等线粒体呼吸代谢相关酶活性变化。结果表明,减压贮藏能较好地保持SDH、CCO、H+-ATPase和Ca2+-ATPase等酶活性,使ATP 含量和能荷在整个贮藏期间均维持在较高水平;采用(10±5) kPa压力处理更有利于维持采后贮藏的能量水平并保持相关酶活性。减压技术在采后保鲜上的作用与能量代谢相关。

Abstract:The effect of hypobaric storage under different pressures on the energy metabolism of juicy peach fruit were studied. The pressures were controlled at (10±5) kPa and (80±5) kPa, respectively with air storage as control. Contents of ATP, ADP, AMP and energy charge, and the activities of mitochondria respiratory metabolism-related enzyme H+-ATPase, Ca2+-ATPase, succinic dehydrogenase (SDH), cytochrome C oxidase (CCO) were determined during storage. The results indicated that the hypobaric storage significantly maintained higher H+-ATPase, Ca2+-ATPase, SDH and CCO activities, and inhibited the decreases of contents of ATP and energy charge level. Hypobaric storage under (10±5) kPa pressure was more conducive to maintain energy level and the activities of mitochondria respiratory metabolism-related enzyme. These results suggested that the benefits of hypobaric storage associated with energy metabolism.

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.
