摘要: 以不套袋‘库尔勒香梨’(Pyrus sinkiangensis Yü‘Korla Xiangli’)果实为对照,采用高效液
相色谱(HPLC)技术、顶空固相微萃取(HS–SPME)结合气相色谱—质谱(GC–MS)联用技术,分
析了套紫色塑料膜袋和单层白色纸袋(NK-15 小林袋)对果实可溶性糖、有机酸和香气物质的影响。结
果表明:(1)果实套紫色塑料膜袋后糖组分含量没有显著变化,套单层白色纸袋后蔗糖和山梨醇含量显
著减少(P < 0.05),而葡萄糖和果糖含量变化不显著;(2)果实套紫色塑料膜袋后苹果酸含量显著减少(P <
0.05),套单层白色纸袋后柠檬酸含量显著升高(P < 0.05),而莽草酸、草酸和奎尼酸含量在各处理间没
有显著变化;(3)不同处理之间香气物质组成和含量差异较大,套袋果实香气物质总含量低于对照,种
类有所减少,特别是“果香型”的酯类化合物明显受到抑制。研究认为,套袋不利于果实整体风味的形
成,但紫色塑料膜袋对果实风味物质的负面影响比单层白色纸袋小,结合成本、工效等因素考虑,建议
在香梨套袋栽培中优先选择紫色塑料膜袋。

Abstract: Bagging is an effective method of improving fruit quality in fruit production and has been widely used to improve fruit appearance,decrease pesticide/fungicides residues and increase commercial value. In order to compare the effects of different bag materials on internal fruit quality,the effects of purple plastic film bag and single-layer white paper bag(Kobayashi NK-15)on soluble sugars,organic acids,and aroma compounds in Pyrus sinkiangensis Yü‘Korla Xiangli’fruit were investigated by high performance liquid chromatography(HPLC),headspace solid-phase microextraction(HS–SPME)combined with gas chromatography-mass spectrometry(GC–MS)with non-bagged fruit as control. The results showed:(1) There were no significant differences in sugars contents between fruit with purple plastic film bag and non-bagged fruit. The contents of sucrose and sorbitol in fruits with single-layer white paper bag were significantly lower than that of non-bagged fruit(P < 0.05)but there were no significant differences in the contents of glucose and fructose. (2) Compared with non-bagged fruit,the content of malic acid were reduced significantly(P < 0.05)in fruit with purple plastic film bag and the contents of citric acid in fruit with single-layer white paper bag were increased significantly(P < 0.05). However,there were no significant differences in the contents of shikimmi acid,oxalic acid and quinic acid among different treatments. (3) There were distinct differences in the composition and contents of volatile compounds among different treatments. Bagging reduced volatiles varieties and relative contents of pear fruit,especially for esters with fruity smell. These results potentially suggest that bagging limite formation of whole fruit flavor,but the negative effects of plastic film bag on fruit flavor compounds lower than paper bag,and therefore the plastic film bag should be selected firstly in bagging cultivation of‘Korla Xiangli’fruit together with cost and work efficiency.
