摘要
本研究优化了有机溶剂稀释法结合气相色谱-燃烧-同位素质谱仪(GC-C-IRMS)测定白酒中乙醇中碳同位素比值(δ13C)的方法。分析了5种年份原酒、24种市场流通固态法白酒以及14种固液法白酒的δ13C值。结果表明:同系列的年份原浆酒中乙醇δ13C值基本无差异;酒中乙醇δ13C值与酿酒粮食和产地有一定关系;利用δ13C鉴别固液法和固态法白酒具有一定可行性。
The research method that stable carbon isotope composition(δ13C) of ethanol in Baijiu were determined by gas chromatography-combustion-isotope ratio mass spectrometry(GC-C-IRMS) with the pretreatment of dilution by organic solvent has been optimized. The δ13C of 5 base Baijiu, 24 Baijiu made by traditional fermentation and 14 Baijiu made from traditional and liquid fermentation have been analyzed. The results show that the δ13C values of 5 base Baijiu have no significant difference. The δ13C values of the ethanol in Baijiu is related to cereal for Baijiu-making and producing area. Using δ13C to distinguish Baijiu made by traditional fermentation and made from traditional and liquid fermentation is possible.
