摘　　要：基于液相色谱-串联质谱联用法测定莲雾在典型电商运输及贮藏过程对其理化性质和花青素含量的影响分析。以莲雾为试验试材,从果园采摘后模拟电商包装及其电商运输至实验室,再将其置于(12±1)℃条件下贮藏15 d,测定贮藏期间莲雾理化性质及花青素的含量变化。结果表明,15 d内莲雾色调值维持不变;硬度呈直线下降趋势,15 d降到最低值;可溶性固形物(TSS)含量基本维持不变;总酸含量呈下降趋势;花青素总含量整体趋势不变,6种花青素(飞燕草素、矢车菊素、矮天牛素、天竺葵素、芍药素、锦葵素)中主要含有矢车菊素、天竺葵素2种,其含量呈先升后降的趋势,15 d内最高值分别为2.73 mg/kg和26.93μg/kg;初步分析了典型电商运输及贮藏期间,莲雾理化性质及花青素的变化规律,为莲雾在运输上市时的品质控制提供理论依据。Based on liquid chromatography-tandem mass spectrometry(LC-MS)to determine the effects of wax apples on its atomization properties and anthocyanin content during typical e-commerce transportation and storage.In this experiment,wax apple was used as the experimental material,simulated e-commerce packaging and its e-commerce transportation from the orchard to the laboratory,and then stored at(12±1)℃for 15 d to determine the changes of physical and chemical properties and anthocyanin content during storage.The results showed that the color tone value of wax apple remained unchanged within 15 d,the hardness decreased linearly,from the 15th day to the lowest value,the value of soluble solids(TSS)remained basically unchanged,and the total acid decreased as a whole.The overall trend of the value of total sugar remained unchanged.Six kinds of anthocyanins(scutellarin,chrysanthemum,dwarf,geranium,paeoniflorin and geranithin)mainly contained two kinds of anthocyanins:pyrethrin and geranithin.The content value increased first and then decreased,and the highest values in 15 d were 2.73 mg/kg and 26.93μg/kg,respectively.This study preliminarily analyzed the changes of physical and chemical properties and anthocyanins of wax apple during typical e-commerce transportation and storage,so as to provide a theoretical basis for the quality control of wax apple during transportation and listing.
