浒苔挥发性风味成分分析

采用顶空固相微萃取-气质联用法对新鲜肠浒苔的挥发性风味成分进行测定，并加以感官评定分析比较风味物质组成。结果表明：浒苔的主要特征性风味物质是顺-3-十七烯，该物质在新鲜肠浒苔中含量高达59.54%，其次是棕榈醛、(E,E)-2,4-庚二烯醛、β-紫罗兰酮、壬醛、反式-2-己烯醛、2,4-戊二烯醛以及反,反-2,4-癸二烯醛等。

Analysis of Volatile Flavor Compounds from Enteromorpha intestinalis

Headspace solid phase microextraction(HS-SPME) coupled with gas chromatography-mass spectrometer(GC-MS) was used to determine the volatile flavor compounds of the green macroalga Enteromorpha intestinalis.A comparative sensory evaluation of the main flavor substances was also done.The results showed that the main characteristic volatile flavor compound of Enteromorpha intestinalis were(Z)-3-heptadecene,with a content as high as 59.43% in fresh samples.The other volatile flavors were hexadecanal,(E,E)-2,4-heptadienal,beta-ionone,nonanal,(E)-2-hexenal,2,4-pentadienal,(E,E)-2,4-decadienal,and so on.
