摘　　要：研究了不同浓度臭氧处理下香椿低温贮藏期间呼吸强度、可溶性蛋白含量、VC含量、谷胱甘肽含量、总酚含量、总黄酮含量、花青素含量、总抗氧化能力、超氧阴离子含量及过氧化氢含量的变化。结果表明,随着贮藏时间的延长,香椿呼吸强度、超氧阴离子和过氧化氢含量呈现逐步上升的趋势,但可溶性蛋白、VC、谷胱甘肽、总酚、总黄酮和花青素含量及总抗氧化能力呈现出逐步下降的趋势。臭氧浓度为8.56 mg/m^(3)处理组的香椿各项指标均优于其他处理组。但当臭氧浓度达到12.84 mg/m^(3)时,对香椿造成了损伤并加速其衰老褐变。The changes of respiratory intensity,soluble protein,vitamin C,glutathione,total phenols,total flavonoids,anthocyanins,total antioxidant capacity,superoxide anion and hydrogen peroxide contents of Toona sinensis during cold storage were studied.The results showed that the respiratory intensity,the contents of superoxide anion and hydrogen peroxide increased gradually as the extension of storage time,yet the contents of soluble protein,vitamin C,glutathione,total phenols,total flavonoids and anthocyanins and total antioxidant capacity decreased gradually. The quality indexes of Toona sinensis treated with ozone concentration of 8.56 mg/m^(3) were better than those of other treatment groups. However, when the ozone concentration reached 12.84 mg/m^(3), damages to Toona sinensis and were caused in addition to accelerating its aging and browning.
