摘要:

本实验采用同时蒸馏萃取- 气谱- 质谱(SDE-GC-MS)联用技术对5 株德氏乳杆菌保加利亚亚种L.b-01、L.b-3、L.b-MYC、L.b-SP1.1 和L.b-M01A 发酵乳中风味物质进行了定性和定量测定,经分析分别有13、19、11、9、12 种成分为发酵乳的风味物质,共涉及酸类化合物、酯类化合物、醇类化合物、羰基化合物、芳环和杂环化合物6 大类、22 种物质。除L.b-M01A 菌产乙醇、乙酸含量较高外,其他各菌株间未发现存在明显的代谢差异。

Abstract:

In the study, 5 fermented milk samples were respectively by 5 strains of Lactobacillus delbruechii ssp. bulgaricus L.b-01, L.b-3, L.b-MYC, L.b-SP1.1 and L.b-M01A were analyzed with SDE-GC-MS (simultaneous distillation-extraction-gas chromatography-mass spectrometry) to assess the difference of flavor compounds among them. The results showed that the kinds of flavor compounds in the 5 samples are 13, 19, 11, 9 and 12 respectively, including 22 compounds in 6 kinds: acids, esters, alcohol, carbonyls, aromatic compounds and heterocyclic compounds. The obvious diversities of flavor compounds in these different samples fermented respectively by 5 strains of Lactobacillus delbruechii ssp. bulgaricus are not found, except higher content of ethanol and acetic acid in the sample fermented by L.b-M01A.

Key words: fermented milk, flavor compounds, Lactobacillus delbruechii ssp. bulgaricus, SDE-GC-MS
