| 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. |
