摘要
以“红露”苹果品种为试材,采用显著性差异分析方法,研究了套袋与不套袋处理对果实品质的影响,以期为贵州苹果种植产业发展提供参考依据。结果表明:与套袋处理相比,不套袋处理提高了果实的着色指数、硬度、维生素C、可溶性糖、可滴定酸、可溶性固形物、蛋白质含量,糖酸比以及固酸比,但降低了果实光洁指数和含水量。除了元素Hg含量一致且无显著性外,套袋处理中元素Pb、Cd、As、Se、Fe、Ni和Sr含量显著高于不套袋,而元素Zn、Co、B、Mn、Ca和Mg含量则显著低于不套袋,其中套袋与不套袋处理果实中元素Pb和Cd均未超出《食品安全国家标准食品中污染物限量》(GB 2762-2017)限量值。不套袋处理比套袋处理果实的着色更浓郁、甜度更高、风味更佳、基础养分更高、矿质元素含量和食用安全性更高,且生产成本相对更低,具有更高的营养价值与经济价值。
Taking the‘Honglu’apple variety as the experimental material,the significance difference analysis method was used to study the effects of bagging and non bagging treatments on fruit quality,in order to provide reference for the development of Guizhou apple planting industry.The results showed that compared with bagging treatment,non bagging treatment increased fruit color index,hardness,vitamin C,soluble sugar,titratable acid,soluble solids,protein,sugar-acid ratio and solid-acid ratio,but decreased fruit smoothness index and water content.Except that the content of Hg was consistent and not significant,the content of Pb,Cd,As,Se,Fe,Ni and Sr in bagging fruits was significantly higher than that in non bagging fruits,while the content of Zn,Co,B,Mn,Ca and Mg was significantly in bagging fruits lower than that in non bagging fruits.The content of Pb and Cd in bagging and non bagging fruits did not exceed the limit value of the National Food Safety Standard Limits of Pollutants in Food(GB 2762-2017).Compared with bagging treatment,non bagging treatment had stronger color,higher sweetness,better flavor,higher basic nutrients,higher mineral element content and food safety,and lower production cost,which had higher nutritional value and economic value.
