The effect of each compound on the overall flavor was discussed. A total of 66 compounds were identified including 14 hydrocarbons, 23 aldehydes, 4 alcohols, 7 ketones, 4 phenols, 3 acids, 2 esters, 2 lactones and 7 heterocyclic compounds. The prominent compounds were hydrocarbons, aldehydes, acids, ketones and heterocyclic compounds, accounted for 17.44%, 45.41%, 13.26%, 3.65% and 2.79%, respectively.
