【摘要】：本文旨在探讨不同品牌的橄榄油挥发性风味物质的差异,为研究鉴别不同品牌的橄榄油提供参考。方法:运用电子鼻和顶空固相微萃取-气质联用仪(HS-SPME-GC-MS)对不同品牌的橄榄油挥发性物质进行检测和分析。结果表明:电子鼻能灵敏地检测到不同品牌橄榄油气味的差异性。GC-MS在不同品牌的橄榄油中检测出76种挥发性物质,主要为烃类、醇类、醛类、酮类、酯类、酸类及其他化合物。酸类物质是除帆船牌特级初榨橄榄油外其他4种橄榄油都具有的物质,1号曼托瓦特级初榨橄榄油特有的关键挥发性化合物是癸烷、E-2-庚烯、6-乙基-2-甲基辛烷、戊醛、庚醛、辛醇和2-辛酮;2号百一牌特级初榨橄榄油特有的挥发性物质是1-癸烯和2,2,4,6,6-五甲基庚烷;3号福恩牌特级初榨橄榄油特有的化合物是1-十三烯和辛烷;4号帆船特级初榨橄榄油特有的化合物是十二烷、3,5-二甲基辛烷、D-柠檬烯和3,7-二甲基-1-辛醇;5号斯巴达(金)特级初榨橄榄油特有的化合物是(E)-2-己烯醛。不同品牌的橄榄油之间共有的关键风味化合物主要有己醛和壬醛。结论:橄榄油品牌不同,主要的挥发性成分种类及其相对含量有差异。
[Abstract]:The purpose of this paper is to explore the differences of volatile flavor substances in different brands of olive oil and to provide references for the identification of different brands of olive oil. Methods: the volatile substances of different brands of olive oil were detected and analyzed by electronic nose and headspace solid phase microextraction-GC-MS. The results showed that the electronic nose could detect the difference of olive oil smell of different brands. GC-MS could detect 76 volatile substances in different brands of olive oil, mainly hydrocarbons, alcohols, aldehydes, ketones, esters, acids and other compounds. Acids are all four kinds of olive oil except for sailboat virgin olive oil. The key volatile compounds of No.1 Mantovat grade virgin olive oil are decane, E-2-heptene, 6-ethyl-2-methyl octane, pentaldehyde, heptanal, Octanol and 2-octanone; 1-decene and 2o-2o-6-6-5-methyl heptane; 1-tridecene and octane, 1-tridecene and 1-octane, 1-tridecene and octane The specific compounds of olive oil are dodecane 3, 5-dimethyl octane, D-limonene and 3, 7-dimethyl-1-octanol, and 5-Sparta (gold) super-virgin olive oil is characterized by Ezac-2-hexenal. The key flavor compounds shared by different brands of olive oil are hexanal and nonaldehyde. Conclusion: the main volatile components and their relative contents are different among olive oil brands.
