Abstract: The detecting results of fermented milk by pure Streptococcus thermophilus with SDE-GC-MS showed that 13 kinds of flavour compounds are identified as follows: 5 kinds of esters,1 kind of alcohol, 4 kinds belong to acids, 1 kind of aldehyde and 2 kinds of ketones. Among of them the contents of two kinds of main flavour compounds, 2,3-Butanedione and 2,3-pentanedione, are 0.241μg/ml and 0.223μg/ml respectively.
