摘  要:
采用气相色谱-质谱联用技术研究套袋处理对肥城桃果实香气品质的影响。结果共检测到40种香气成分,且被分成6类,分别是酯类、内酯类、醇类、醛类、酮类和有机酸类。未套袋果实中检测出36种成分,套袋果实中检测出30种成分;其中(E)-2-己烯-1-醇、乙酸乙酯、苯甲醛、1-己醇、己醛、(Z)-3-己烯-1-醇等为肥城桃果实的特征性香气成分。C6醛类和C6醇类这些清香型化合物在套袋与不套袋处理果实中的相对含量分别占到了54.92%和53.00%;酯类和内酯类这些果香型化合物在套袋与不套袋处理果实中的相对含量分别为25.95%和26.60%。套袋处理之后的果实各类香气物质的相对含量与不套袋处理的果实差别不大,但香气成分种类减少,主要体现在果香型化合物上,这可能是导致肥城桃果实套袋后风味变淡的原因。

摘  要:
The effects of bagging on aroma compounds in Feicheng peach [Prunus persica(L.)Batsch cv.Feicheng] was tested by GC-MS.A total of 40 compounds were identified from the sample extracts,which were divided into six groups,esters,lactones,alcohols,aldehydes,ketones and organic acids.36 compounds were identified from unbagged fruits while 30 were identified from bagged fruits.(E)-2-Hexen-1-ol,Ethyl acetate,Benzaldehyde,1-Hexanol,Hexanal and(Z)-3-Hexen-1-ol were the characteristic aroma components in Feicheng peach.The components of green note flavor compounds,C6 aldehydes and C6 alcohols,accounted for 54.92% and 53.00% in bagged and unbagged fruits respectively.The components of fruity note,esters and lactones contributed to 25.95% and 26.60% in bagged and unbagged fruits respectively.The relative content of aroma components in bagged and unbagged fruits didn't differ significantly;while the kinds of aroma reduced in bagged fruits,mainly fruity note compounds,which might weaken the flavor of fruits.
