摘要
采用顶空固相微萃取-气相色谱-质谱法对北京油鸡中的挥发性风味物质进行测定。结果共检测出105种风味化合物,其中包括醛类8个(21.11%)、酮类2个(0.52%)、醇类8个(2.66%)、烃类71个(66.29%)、酯类9个(7.55%)、酸类3个(1.39%)、其他杂环类4个(0.48%)。醛和含硫杂环化合物是北京油鸡的主要香味成分。
In this study, volatile components in Beijing chicken were determined by solid phase microextraction and gas chromatography-mass spectrometry (GC/MS). Totally 105 components were identified as aldehydes (21.11%), ketones (0.52%), alcohols (2.66%), hydrocarbons (66.29%), esters (7.55%), acids (1.39%), and other components (0.48%). Among these compounds, aldehydes containing sulfur and heterocyclic compounds were the major components for the flavor of Beijing chicken,
