Effects of Space Electric Field Combined with Ethylene Absorbent on Quality and Physiology of Prune Fruit during Postharvest Storage
In this study,prunes were used as the experimental material and subjected to a combined treat-ment of spatial electric fields and ethylene adsorbents.The prunes were subsequently stored in a low-tem-perature environment ranging from-1.5℃to 1.0℃to evaluate the effects on various postharvest quali-ty parameters.The primary objective was to determine the impact of the treatment on fruit hardness,solu-ble solids content,titratable acidity,ascorbic acid content,weight loss,respiration rate,and cell membrane permeability throughout the storage period.The results demonstrated that the integrated treatment of spa-tial electric fields and ethylene adsorbents significantly mitigated the reduction in fruit hardness and pre-served the soluble solids content and delayed the decrease of titrated acid and ascorbic acid content.Specif-ically,after 90 days of storage,the fruit hardness and soluble solid content were 55.18%and 12.87%higher than those observed in the control group,respectively(P<0.05).Furthermore,the treatment no-tably delayed the onset of the respiratory peak and curbed the increase in cell membrane permeability,lead-ing to a significant reduction in fruit weight loss(P<0.05).The comparative analysis of the quality and physiological indices of prunes subjected to different treatments revealed that the application of electric fields in conjunction with an ethylene adsorbent effectively maintained superior fruit quality during the storage period.
