摘要: 采用动态顶空的方法对红烧牛肉罐头中挥发性化合物进行提取,热脱附系统进样,利用气相-嗅闻-质谱联用的方法对其中的香味活性化合物进行定性定量分析,共鉴定出73中挥发性化合物,其中23种香味活性化合物,这些化合物种类主要有酮类4种,醛类3种,醇类2种,酯类2种,呋喃类2种,吡嗪类2种,噻唑类2种,萜类2种,烯类1种,吡啶1种。红烧牛肉罐头中重要的香味活性化合物有2-丁酮(水果味)、2-戊酮(甜味、果香味)、莰烯(木香味、薄荷味)、丁酸乙酯(香甜味、水果味)、吡啶(酸味、鱼香味)、2,5-二甲基-吡嗪(烧烤味、坚果味)、苯甲醛(甜味、果香味)、2-乙酰噻唑(坚果味、烤花生味)。

Abstract: The aroma-active compounds of canned stewed beef braised in brown sauce were qualitatively and quantitatively analyzed by dynamic headspace sampling, thermal desorption injection and GC-O/GC-MS. A total of 73 volatile compounds were identified. Among them were 23 aroma-active compounds, mainly consisting of 4 ketones, 3 aldehydes, 2 alcohols, 2 esters, 2 furans, 2 pyrazine, 2 thiazole, 2 terpenes, 1 alkene, and 1 pyridine. The important aroma-active compounds were 2-butanone (fruity) , 2-pentanone (fruity and sweet) , camphene (woody and minty) , ethyl butyrate (sweet and fruity), pyridine(soul and fishy), 2,5-dimethyl-pyrazine(nut and roast), benzaldehyde (sweet and fruity), and 2-acetylthiazole (nut and roast peanut).

Key words: canned stewed beef, dynamic headspace sampling, aroma-active compounds, gas chromatography-olfactometry-mass spectrometry (GC-O-MS)
