The contents of methanol and fusel oils in various types of wines were determined using headspace-gas chromatography (HS-GC). The HS-GC analysis method showed good linearity, high precision and accuracy, and low LOQ and LOD values. The methanol content in 289 types of wines ranged from not detected (ND) to 333.84 mg/kg, and was higher in Korean grape wines than in imported grape wines. Among fusel oils, the contents of 1-propanol (23.61-84.23 mg/kg) and isobutanol (34.98-111.39 mg/kg) were slightly higher in Korean wild grape wines, whereas that of isobutanol (ND to 55.26 mg/kg) was slightly lower in Korean black raspberry wine than in the other wines. The contents of amyl alcohol were lower in Korean plum wine and Korean black raspberry wine than in all of the wines included in the present study, and highest in imported grape wines.
采用顶空气相色谱法（HS-GC）测定了各类葡萄酒中甲醇和杂醇油的含量。HS-GC分析方法具有良好的线性、高精度和准确性，以及较低的定量限（LOQ）和检测限（LOD）值。289种葡萄酒中的甲醇含量在未检出（ND）至333.84mg/kg之间，韩国葡萄酒中的甲醇含量高于进口葡萄酒。在杂醇油中，韩国野生葡萄酒中1-丙醇（23.61-84.23mg/kg）和异丁醇（34.98-111.39mg/kg）的含量略高，而韩国黑莓酒中异丁醇（ND至55.26mg/kg）的含量略低于其他葡萄酒。韩国李子酒和韩国黑莓酒中戊醇的含量低于本研究中的所有葡萄酒，进口葡萄酒中戊醇的含量最高。
