高浓度CO2短时处理对西梅采后贮藏品质及抗氧化代谢的影响
Effects of Short-term Treatment with High Concentration CO2 on Post-harvest Storage Quality and Antioxidant Metabolism of Plums
摘要
Abstract
'Franch'plums were used as experimental material to elucidate the effects of short-term treatment with high concentration of carbon dioxide(CO2)on post-harvest storage quality and antioxidant metabolism.The fruits were treated with 45％,60％,and 75％CO2 for 3 hours,and then stored at 1.0±0.5 ℃ for 49 days.The firmness,color,soluble solids content,titratable acid content,and indicators related to antioxidant metabolism of the plums were measured during cold storage.The results showed that short-term treatment with high concentration CO2 can effectively maintain the firmness,color,soluble solids,and titratable acid content of plums,among which 60％CO2 treatment showed the best effects in maintaining fruit quality.At the end of storage,the activities of superoxide dismutase(SOD),catalase(CAT),peroxidase(POD),glutathione reductase(GR),and ascorbate peroxidase(APX)in the 60％CO2 treatment group were 5.71％,59.95％,27.40％,29.18％,and 45.00％(P＜0.05)higher than those in control group,respectively.The contents of ascorbic acid(AsA)and glutathione(GSH)were 1.42 and 1.23 times higher than the control group,respectively.This increased the activity of antioxidant enzymes,maintained the content of AsA and GSH,reducing the production rate of superoxide anion(O2-·),and delaying the accumulation of hydrogen peroxide(H2O2)content,malondialdehyde(MDA)content and the increase in cell membrane permeability.These results indicate that short-term treatment with high concentration CO2 can enhance the antioxidant metabolism of plums during storage,thereby preserving fruit quality.关键词
