摘要
该文以蓝果忍冬品种“蓝精灵”为试材,研究微环境气调对蓝果忍冬在低温贮藏期间果实感官品质、生理指标、营养成分、抗氧化酶活性的影响。实验结果表明,与对照相比,mMA能够有效维持蓝果忍冬果实自身的感官品质和营养成分,到贮藏期末期(60 d)时,mMA处理后果实中的抗坏血酸、花色苷,黄酮、总酚含量分别为123.09 mg/100g、203.77 mg/100g、69.57 mg/100g和18.45 mg/g,分别为对照组的1.64、1.61、2.43和2.51倍。此外,mMA还能显著抑制果实自身呼吸强度的增强,维持果实的硬度水平。在抗氧化活性方面,mMA可以有效地延缓还原型谷胱甘肽(reduced glutathione,GSH)、氧化型谷胱甘肽(oxidized glutathione,GSSG)及总谷胱甘肽(glutathione,T-GSH)含量的降低,促进超氧化物歧化酶(superoxide dismutase,SOD)、谷胱甘肽还原酶(glutathione reductase,GR)活力的增加,并抑制丙二醛的产生。结果显示,mMA对蓝果忍冬果实在贮藏期的各项生理、贮藏品质及抗氧化酶活性都能够起到积极的作用,延长蓝果忍冬贮藏保鲜时间15~20 d。
Using the blue honeysuckle fruits variety“Lanjingling”as the test material,the effects of the micro-environmental atmosphere on blue honeysuckle fruits sensory quality,physiological indicators,nutrients and antioxidant enzyme activities during low-temperature storage were studied.Compared with control,mMA can effectively maintain the sensory quality and nutritional of blue honeysuckle fruits.By the end of the storage period 60 days,the ascorbic acid,anthocyanin,flavonoids,and total phenol contents in the fruit after mMA treatment were 123.09 mg/100g,203.77 mg/100g,69.57 mg/100g and 18.45 mg/g,which were 1.64,1.61,2.43 and 2.51 times higher than the control group respectively.In addition,mMA can significantly inhibit the respiration rate and maintain the firmness of the fruits.In terms of antioxidant activity,mMA can effectively delay the decrease of reduced clutathione(GSH),oxidized glutathione(GSSG)and glutathione(T-GSH)activity,promote the increase of antioxidant enzyme superoxide dismutase(SOD)and glutathione reductase(GR)activity,and inhibit the production of malondialdehyde to maintain the antioxidant capacity of the fruits.The storage quality of blue honeysuckle fruits was significantly affected by mMA,prolonged the storage time 15-20 days.
