摘　　要： 采用高效液相色谱法测定发酵液中甘氨酸含量和顶空气相色谱法测定酒中甲醇含量,研究了发酵液中甘氨酸与其生成甲醇的关系。结果表明,甘氨酸浓度在0～0.9 g/L范围内与酿造酒中甲醇生成呈线性关系,线性方程:Y=103.3X-4.5,甘氨酸转化率为24.2%。 The concentration of glycine was detested by high performance liquid chromatography（HPLC） and the concentration of methanol in liquor was detected by headspace gas chromatography（HS-GC）.The relations between methanol and glycine in fermented liquid were studied.The results showed that there was linear relationship between glycine（concentration within 0～0.9 g/L） and methanol in liquor and the linear equation was Y=103.3X-4.5 with the conversion rate of glycine as 24.2 %.

关 键 词： 酿造酒 甘氨酸 甲醇
