摘要:
本文以荔枝新品种‘翡脆’、传统大宗品种‘桂味’为试材,分析了运用冰袋结合电商包装的物流包装贮运方法下荔枝果实采后生理及贮藏品质变化,同时也探究了‘翡脆’品种的贮藏特性。结果表明,电商物流包装贮运方式显著(P<0.05)降低了荔枝果实的呼吸强度、相对电导率;减缓了荔枝可溶性固形物(TSS)、可滴定酸(TA)及VC含量的下降,并抑制了ΔE*值的上升和L*值的下降,保持了较好的果实感官品质。电商物流包装贮运方式还显著(P<0.05)降低了贮运期间特别是贮运中后期荔枝的失重率、褐变指数,并维持了较高的好果率,因此电商物流包装贮运方式可延缓果实衰老,延长贮藏期。同时,与‘桂味’相比,荔枝新品种‘翡脆’显示出更低的呼吸强度、相对电导率、ΔE*值及感官品质变化。此外,‘翡脆’荔枝的失重率、褐变指数低于‘桂味’,好果率及贮藏期均高于‘桂味’,表明‘翡脆’荔枝有着较好的持水性和耐贮性。

Abstract:
In this paper,the changes of physiological and storage quality in postharvest fruits under logistics packaging and storage using ice bag combined with e-commerce packaging were analyzed with the new litchi variety ‘Feicui’ and the traditional variety ‘Guiwei’ as test materials,and the storage characters of the new cultivar ‘Feicui’ was explored. The results showed that,e-commerce logistics packaging and storage significantly(P<0.05)reduced the respiratory intensity and relative conductivity of litchi fruit,delayed the decreasing of soluble solids(TSS),titratable acid(TA)and VC contents,inhibited the increasing of ΔE* value and the decreasing of L* value,maintained a good sensory quality of litchi fruit. The weight loss rate and browning index of litchi during storage,especially in the middle and late stages of storage,were significantly(P<0.05)reduced,and the good fruit rate was maintained. Therefore,e-commerce logistics packaging and storage mode could delay fruit senescence and prolong storage period. At the same time,compared with ‘Guiwei’,the new litchi variety ‘Feicui’ showed lower respiratory intensity,relative conductivity,ΔE* value and sensory quality changes. In addition,the weight loss rate and browning index of ‘Feicui’ were lower than ‘Guiwei’,and the good fruit rate and storage period were higher,which indicated that ‘Feicui’ litchi had better water holding capacity and storage resistance.
