建立了同时检测烘焙食品中椰子醛、反式杨梅醛、顺式杨梅醛、桃醛四种香料的气相色谱-质谱方法.样品采用乙酸乙酯提取,经过低温速冻净化后,毛细管气相色谱柱(ZB-5,30 m×0.25 mm×0.25 μm)分离,采用选择离子监测模式进行气相色谱质谱测定,外标法定量.方法学研究结果表明:目标化合物椰子醛、反式杨梅醛、顺式杨梅醛、桃醛在0.05~5.00 μg/mL浓度范围内具有良好线性关系,相关系数为R2≥0.999,方法定量限为0.01~0.04 mg/kg;回收率为81.3%~95.8%,相对标准偏差为2.43%~4.95%.该方法简单快捷,准确可靠,灵敏度高,可以用于烘焙食品中四种香料含量的测定.
Simultaneous determination of 4 kinds spices in baked food by gas chromatography-mass spectrometry
A method for simultaneous determination of four kinds spices in baked food by gas chromatography-mass spec-trometry was developed.The samples wereextracted byethyl acetate,separated with ZB-5 capillary column(30 m× 0.25 mm×0.25 μm)anddetermined by GC-MS under selected ion monitoring(SIM),Then quantified by external standard meth-od.The method showed that the aim compoundsgamma nonalactone、trans strawberry aldehyde、cis strawberry aldehyde、gamma undecalatonein the range of 0.05 ug/mL-5.00 ug/ml there are good linears correlation(R2≥0.999),Quantification Limits were less than 0.04 mg/kg.The recoveries of standard addition were 81.3%-95.8%and the RSDs were in the rang-es of 2.43%-4.95%.This test provided with accurate,sensitive,and reliable analysis method for four kinds spices in baked food.
