【中文摘要】 姬菇子實(shí)體在5℃、25℃下貯藏6d,測定纖維素酶、淀粉酶、過氧化氫酶活性,研究其在采后衰老軟化過程中的生理生化變化規(guī)律。結(jié)果表明,姬菇子實(shí)體在25℃貯藏56d,其纖維素酶、淀粉酶活性較5℃處理的高;貯藏4d,其過氧化氫酶活性較5℃處理的低,清除自由基的能力較弱,從而使25℃處理組的菇體易快速衰老軟化,而5℃處理組貯藏15d不軟化。研究表明,姬菇子實(shí)體采后貯藏保鮮與纖維素酶、淀粉酶、過氧化氫酶活性有關(guān)。
【英文摘要】 The activities of cellullase,amylase,catalase of Pleurotus cornucopiae fruitbodies stored for 6 days under the temperatures of 5℃ and 25℃ were determined in order to study the physiological and biochemical change law during the postharvest senescence and softening process.The results showed that Pleurotus cornucopiae fruitbodies stored in 25℃ had higher activities of cellullase and amylase,but lower activity of catalase than those stored in 5℃.So Pleurotus cornucopiae fruitbodies stored in 25℃ were senescence and soft quikly.Pleurotus cornucopiae fruitbodies stored for 1～6 days under 5℃ were not soft and had long storage life.This indicated that the fresh-keeping of Pleurotus cornucopiae fruitbodies had relationship with enzyme activities of cellullase,amylase,catalase during the postharvest storage period.
