LED光照处理对豇豆采后贮藏品质和生理特征的影响
Effect of LED irradiation on storage quality and physiological property of cowpea during postharvest storage
摘要
Abstract
To study the effect of LED light irradiation treatments on physiological changes of cowpea during postharvest storage,the intensity of 40 μmol· m-2 · s-1 two monochromatic light,LED white light,blue light were used to irradiate the cowpea throughout the storage period,and the changes of storage quality and physiological property were measured at 15 ℃.The results showed that LED light irradiation treatments effectively delayed the decrease of appearance quality and the increase of weight loss at 15 ℃ during the storage.The generation and development of rusty spots were inhibited.The degradation of total soluble solid and chlorophyll were retarded.The accumulation of MDA was suppressed,which maintained the integrity of cell membrane.The treatments well maintained the content of total phenolics,meanwhile,enhanced the activities of POD and CAT,which reduced the damage of active oxygen.In this study,the 40 μmol· m-2·s-1 LED white light irradiation had a better effect on cowpea preservation than 40 μmol· m-2· s-1 LED blue light irradiation.关键词
