为了辨别浓香型白酒(strong-flavor Baijiu, SFB)的品牌,利用稳定同位素质谱仪(stable isotope ratio mass spectrometry, IRMS)测定了来自13个品牌共计301个浓香型白酒样品的乙醇、风味物质(异戊醇、己酸乙酯、乳酸乙酯、己酸)稳定碳同位素比值(stable carbon isotope ratios, δ13C)。结果发现,不同品牌浓香型白酒拥有不同稳定碳同位素特征,单独利用乙醇δ13C对浓香型白酒品牌进行判别时,总正确判别率较低,只有44.5%,结合4种风味物质δ13C后,总正确判别率提升到82.7%,说明浓香型白酒中多种物质δ13C相联合的方法能有效的辨别浓香型白酒的品牌。
