中文摘要:在不同的微波处理、微波结合抗褐变剂处理条件下研究了苦瓜多酚氧化酶和过氧化物酶的微波灭酶技术。结果表明:微波功率越大,载样量越少,多酚氧化酶越易失活,而切片厚度在1 cm以下对其活性影响不大。当载样量为40 g时,样品预先在功率800 W的微波下处理1 min,再在质量浓度为0.1 μg/mL的EDTA钠盐溶液浸泡60 min,最后微波间歇处理3 min,则可使其中的多酚氧化酶活性完全钝化。过氧化物酶随微波功率增大而迅速失活,在载样量为40 g、切片厚度为0.5 cm、微波功率为800 W条件下,处理1 min

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.
