    摘要:

    采用顶空固相微萃取-气相色谱-质谱联用法研究3种不同全麦粉添加量(50%、75%和 100%)干挂面和1种精白挂面样品的挥发性成分,共检测到85种挥发性成分,其中包括17种醛,34种烃,16种醇,7种酮,1种呋喃,7种酯,2种胺和1种酸。四种挂面均含有烃类、醛类、醇类、酮类、酯类和胺类化合物。精白挂面和三种全麦挂面中分别检测到44、53、52和50种挥发性成分,全麦挂面相比于精白挂面挥发性成分显著增加。在挥发性成分中醛类物质是最主要物质,相对含量达25%以上。己醛含量显著高于其他醛类物质。全麦粉添加量的增加对各种类挥发性成分构成影响不大,而对各挥发性成分的相对含量有较大影响。

    Abstract:

    Volatile compounds from one kind of refined white noodle and three kinds of dry noodles added with different contents of whole wheat flour (50%, 75% and 100%) were extracted by headspace solid phase micro extraction (HS-SPME) and identified by Gas Chromatography Mass Spectroscopy (GC-MS). A total of 85 volatile compounds were identified in the four dry noodles, including 17 aldehyde, 34 hydrocarbon, 16 alcohol, 7 ketone, 1 furan, 7 ester, 2 amine, 1 acid. The four kinds of noodles contain hydrocarbons, aldehydes, alcohols, ketones, esters and amines. 44, 53, 53 and 50 volatile components were detected in refined white noodles and three kinds of whole wheat noodles, respectively. Compared with refined white noodles, the volatile components in whole wheat noodles were significantly increased. Among the volatile components, aldehydes are the most important substances with relative contents of more than 25%. The content of hexanal in aldehydes was significantly higher than that of other aldehydes. The increase of the amount of added whole wheat flour has little effect on the composition of various volatile components, but has great effect on the relative contents of each volatile component.
