【摘要】 通過測定200μg/L臭氧處理不同時(shí)間(5、101、5 min)后刺芹側(cè)耳(Pleurotus eryngii)子實(shí)體在低溫(4℃)貯藏時(shí)的指標(biāo),研究臭氧處理對刺芹側(cè)耳低溫貯藏的保鮮效果,結(jié)果表明,臭氧處理后刺芹側(cè)耳的細(xì)胞膜透性下降、呼吸強(qiáng)度降低、多酚氧化酶(polyphenol oxidase,PPO)活性降低、褐變反應(yīng)受到抑制;臭氧處理可延長刺芹側(cè)耳的保鮮時(shí)間,其中處理10 min刺芹側(cè)耳子實(shí)體保鮮效果最好。
【Abstract】 The effects of exposing Pleurotus eryngii fruit bodies to 200 μg/L ozone for different time periods on postharvest deterioration during subsequent storage at 4 ℃ were evaluated.Membrane permeability,respiratory activity and polyphenol oxidase activity all decreased,and the browning response was inhibited.Fruit bodies exposed to ozone for 10 minutes maintained their fresh quality for one week.
