摘要

背景白酒是一种中国传统白酒，以谷物为原料，经发酵、蒸馏、陈酿和勾兑而成。白酒的风味受原料、起曲、工艺和环境等因素的影响，由于这些因素与白酒风味之间的关系仍在分析之中，因此不同白酒的鉴别仍有一定难度。结果采用气相色谱-电子鼻（GC-E-Nose）检测出 24 种挥发性物质，采用气相色谱-飞行时间质谱（GC-TOF MS）检测出 99 种挥发性物质。利用偏最小二乘法（PLS）分析了气相色谱-电子鼻（GC-E-Nose）检测到的物质的峰面积，筛选出投影中可变重要度（VIP）大于 1 的物质。结合 GC-TOF MS 的定性结果，筛选出四种物质（异丁酸、2-丁酮、2,3-丁二醇和 3-甲基丁酸）作为强毒瘤白酒的挥发性差异标志物。建立了精确定量这四种物质的外部标准曲线，并通过 Kruskal-Wallis 检验证实这四种物质的绝对含量在不同样品之间存在显著差异（P < 0.01）。根据这四种物质的绝对含量进行主成分分析和层次聚类分析，结果表明不同样品的酒精含量不同，优先级也不同。该研究为检测和提高白酒产品质量提供了理论支持。© 2024 化学工业协会。

Identification of volatile differential markers in strong-aroma Baijiu based on gas chromatography–electronic nose combined with gas chromatography–time-of-flight mass spectrometry

BACKGROUND

Baijiu is a traditional Chinese liquor produced from grains through fermentation, distillation, aging and blending. The flavor of Baijiu is influenced by factors such as raw materials, starter, processes and the environment, and since the relationship between these factors and the flavor of Baijiu is still being analyzed, the identification of different Baijiu is still somewhat difficult. In this paper, the volatile differential markers of 42 types of strong-aroma Baijiu of different origin, alcohol content and grade were explored.

RESULTS

A total of 24 volatile substances were detected by gas chromatography–electronic nose (GC-E-Nose) and 99 volatile substances were detected by gas chromatography–time-of-flight mass spectrometry (GC-TOF MS). The peak areas of the substances obtained by GC-E-Nose were analyzed by the partial least squares (PLS) method, and the substances with variable importance in projection (VIP) >1 were screened out. Combined with the qualitative results of GC-TOF MS, four substances (isobutyric acid, 2-butanone, 2,3-butanediol and 3-methylbutyric acid) were selected as volatile differential markers for strong-aroma Baijiu. An external standard curve was established to accurately quantify these four substances, and the Kruskal–Wallis test confirmed that the absolute contents of these four substances varied significantly among different samples (P < 0.01). Principal component analysis and hierarchical cluster analysis based on the absolute content of these four substances showed that different samples were prioritized for different alcohol contents.

CONCLUSION

These four substances can be used as volatile differential markers of strong-aroma Baijiu samples. This research provides theoretical support for the detection and improvement of Baijiu product quality. © 2024 Society of Chemical Industry.
