摘要
采用同时蒸馏萃取-气相色谱-质谱法,建立了香精的指纹图谱。以二氯甲烷为萃取溶剂,萃取水浴温度为60℃,萃取时间为2.5 h,萃取液经脱水并浓缩后进行GC-MS分析,共检出了22种组分并进行了定性。经综合指数法计算,8批次的香精色谱指纹图谱显示了较高的相似度;同时方法可用于添加其他香精的掺兑样品的区分,表明此法可以用于香精的质量控制。
The chromatographic fingerprint chromatogram of flavor was established by GC MS with simultaneous distillation extraction. Dichloromethane was used as extraction solvent, and temperature of the water bath for extraction and time for extraction taken were 60℃ and 2. 5 h respectively. To tally 22 compounds were separated and identified. Good similarities among the chromatographic fingerprint chromatogram of 8 batches of samples were obtained by comprehensive index method, and samples mixed with other kind of flavor could also be obviously distinguished. Hence, the proposed method can also be used for the quality control of flavor.
