Abstract

The pattern of E-commerce logistics packaging brings problems of anaerobic respiration, alcohol fermentation and off-flavor during the storage and transportation of table grapes. The modified atmosphere combined with micro-porous membrane package was employed in order to improve the quality of postharvest table grapes. The modified atmosphere (5% O2+8% CO2) separately combined with micro-porous membrane M1 (oxygen permeability of 6000 cm3/(m2.d)), micro-porous membrane M2 (oxygen permeability of 8000 cm3/(m2.d)) and polyethylene film (oxygen permeability of 300 cm3/(m2.d)) were used to pack Red Globe and Munage grape, respectively. The time of anaerobic respiration and physiological indexes were determined to evaluate the effects of different E-commerce logistics packages on the postharvest quality of table grapes. The storage conditions were as follow:(0±0.5)℃ for 7 d and then (15±1.0)℃ for 9 d, (15±1.0)℃ for 12 d. The modified atmosphere combined with micro-porous membrane package inhibit the increase of pH and alleviated the decrease of hardness, total soluble solids (TSS), titrate acid (TA), vitamin c (Vc) and total phenol content, which maintained the postharvest quality of Red Globe and Munage grapes. Compared with M2, M1 could better reduce the decay and delay the decrease of TSS, TA and Vitamin C contents. These results demonstrated that modified atmosphere combined with micro-porous membrane M1 avoided the occurrence of anaerobic respiration, maintained the appearance and nutritional quality and delayed the fruit senescence process, which prolonged the shelf life of Red Globe and Munage grapes.
