摘要
本研究采用顶空固相微萃取结合气-质联用技术对6个夏橙(Citrus sinensis(L.)Osbeck cv.Valencia)品系果实成熟期内的香气成分进行动态分析测定.结果表明,Olinda和Delta中酯类物质总含量相对较高,分别占1.88%和2.22%,且6月下旬香气物质丰富;Rhode Red和Campbell中醇类物质总含量相对较高,分别在6月下旬占10.25%和4月下旬占7.78%,此时期香气物质丰富;6月中旬Frost中醛类物质总含量相对较高达15.56%,但4月下旬香气物质最丰富;5月中旬Cutter中香气物质最丰富,总萜类物质相对含量占92.12%.
The aroma components of Valencia Sweet Orange （Citrus sinensis（ L. ） Osbeck cv. Valencia） fruits were dynamically determined by solid phase microextraction （SPME） couples with gas chromatography-mass spectrometry （GC-MS） in maturing. The results showed that total relative content of esters were higher in Olinda （ 1.88 % ） and Delta （2.22 % ） Valencia Sweet Orange fruits respectively, as well as they were rich-aroma in late June; In Rhode Red and Campbell Valencia Sweet Orange fruits, total relative content of alcohols were higher （ containing 10.25 % and 7.78 % , each one） and the two cultivars had more aroma components in late June and late April respectively; In mid-June, total relative content of aldehydes were higher （15.56 % ） in Frost Valencia Sweet Orange fruits but it was full-aroma in late April; Cutter Valencia Sweet Orange had the most aroma components in mid-May, the relative content of total terpenoids were 92.12 %.
