2、性物質(zhì)有醇、醛、含氮含磁化合物、酮、烴、酸、酯、芳香族等,其中解凍鮑魚檢出39種,烘烤鮑魚檢出51種。解凍鮑魚呈清鮮味,略帶腥味,醇、醛類化合物是其主要風(fēng)味物質(zhì),其中苯甲醛(20.83%)、1-辛烯.3.醇(t8.35%)、甲氧基一苯基.肟(13.25%)為最主要特征風(fēng)味物質(zhì)。而烘烤鮑魚風(fēng)味發(fā)生明顯變化,鮮鮑魚固有的清鮮味逐漸消失,烤肉的香味顯著增強,醇類,含氮含硫和酯類化合物是其主要的揮發(fā)性成分來源,其中丁二醇(42.64%)、甲基吡嗪(12.41%)為其最重要特征風(fēng)味物質(zhì)。關(guān)鍵詞:質(zhì)聯(lián)用儀;解凍鮑魚;烘烤鮑魚;揮發(fā)性成分;特征風(fēng)味文章篇號:1673.907
