摘　　要：采用顶空固相微萃取-气相色谱-静电场轨道阱质谱联用法建立同时测定果酒中5种醛酮类和4种呋喃类化合物的分析方法。通过模拟酒液以及枸杞酒、蓝莓酒和山楂酒中检验表明,上述化合物检出限在0.004~6.300μg/L之间,定量限在0.01~21.00μg/L之间,加标回收率均在81%~120%之间,精密度不大于19.08%,该方法准确度高,能够满足果酒中醛酮类和呋喃类化合物定性定量的要求。In this study,headspace-solid-phase microextraction extraction combined with gas chromatography-orbitrapmass spectrometry(HS-SPME-GC-Orbitrap-MS)was used to establish a method for the simultaneous determination of five aldehydes and ketones and four furans in fruit wines.The method was validated on model wine,goji berry wine,blueberry wine and hawthorn wine.The limits of detection(LODs)for all target compounds ranged from 0.004 to 6.300μg/L,and the limits of quantification(LOQs)were between 0.01 and 21.00μg/L.The recoveries of all analytes in spiked wine samples were between 81%and 120%and the relative standard deviations(RSDs)for precision were equal to or less than 19.08%.This method is accurate and can meet the requirements for the quantification of aldehydes,ketones and furans in fruit wines.
