| 摘 要： | 在常温(20±1)℃条件下,研究CO2(80%~90%)处理对磨盘柿感官、营养、生理指标的影响,探讨常温下CO2脱涩处理对磨盘柿品质的影响。结果表明,与对照组相比,CO2处理可显著降低贮藏期间磨盘柿的可溶性单宁含量,同时促进果实果皮强度、L*值、VC、总酚和可溶性固形物含量的降低,加快果实呼吸强度和乙烯生成速率的升高,提高果实相对电导率和丙二醛(MDA)含量的上升速率。主成分分析(PCA)显示,CO2处理方式与呼吸强度、乙烯生成速率的相关性较高。通过SUS-plot图和VIP值具体分析可得磨盘柿两种处理的差异指标为果皮强度、呼吸强度和VC。说明CO2脱涩虽达到较好较快的脱涩效果,却加速了果实的品质降低,引起磨盘柿软化现象发生。

| Abstract: | In the present study,the effects of CO2(80%~90%)treatment on the sensory,nutritional and physiological indexes of Mopan persimmon at room temperature(20±1)℃were studied,aiming to discuss the effects of CO2 deastringency on the qualities.Results showed that CO2 treatment could significantly reduce the soluble tannin content of Mopan persimmon during storage,promote the decrease of peel strength,L*,VC,total phenols and total soluble solids,accelerate the increase of respiration intensity and ethylene production rate,and increase the relative conductivity and malondialdehyde(MDA)rising rate compared with that in control group.Principal components analysis(PCA)showed that CO2 treatment had a high correlation with respiration intensity and ethylene production rate.Through the analysis on SUS plot and VIP value,the difference indices of Mopan persimmon were peel intensity,respiration intensity and VC.These results indicated that CO2 deastringency achieved better and faster deastringency effects,but it would accelerate the decline of fruit quality and cause the softening phenomenon of Mopan persimmon. |
