摘要
建立气相色谱—质谱测定葡萄酒中乙醛含量的方法,并考察提取溶剂、解析pH、衍生化实际用量等因素对定量结果的影响。结果表明:该方法检测限为0.12 mg/kg,线性范围为0.2~100.0mg/kg(R^2=0.999 4),样品三水平加标回收率为89.3%~113.0%,平均相对标准偏差为1.28%~9.42%(n=6),适用于葡萄酒中乙醛总量的测定。
A method for determination of acetaldehyde in wine by gas chromatography-mass spectrometry（GC-MS）was established,in which the influence factor on the detected results were studied,such as extraction agent,desorption pH,derivatization reagents.As a result,the limit of determination（LOD）of vanillin and ethyl-vanillin was 0.12 mg/kg.linearity range was 0.2~100.0 mg/kg（R^2=0.999 4）,The spiked recovery was between 89.3% ~113.0%,and the RSD ranged from 1.28%~9.42%（n=6）.This method was applicable for determination of acetaldehyde in wine.
