在(2±1)℃、相对湿度95%的环境中,通过调节气调袋内氧气体积分数(1%、2%、3%、5%)来贮藏金针菇,定期检测呼吸强度、褐变度(BD)、过氧化物酶(POD)、超氧化物歧化酶(SOD)、丙二醛(MDA)等生理生化指标,研究气调贮藏(modified atmosphere storage,MAS)对金针菇影响.结果表明体积分数3%低氧处理可以抑制金针菇的呼吸作用,维持较高的POD、SOD酶活性,抑制MDA含量的增加,减缓营养成分的损失,有助于延缓衰老,延长贮藏期.

Respiratory intensity,browning degree (BD),peroxidase (POD) and superoxide dismutase (SOD) activities,and malondialdehyde (MDA) content of postharvest Flammulina velutipes modified atmosphere stored under the conditions of 2℃,95% relative humidity and different oxygen concentrations (1%,2%,3% or 5%) were examined at regular intervals.Results showed that low concentration (3%) oxygen treatment effectively inhibited respiratory intensity and the increase of MDA content,maintain high levels of POD and SOD activities,reduced nutrient loss,and helped delay senescence and prolong storage period of Flammulina velutipes.
