Quantification of volatile compounds in Chinese soy sauce aroma type liquor by stir bar sorptive extraction and gas chromatography-mass spectrometry

BACKGROUND: Considering the important of aroma compounds on the quality of baijiu, stir bar sorptive extraction (SBSE) coupled with gas chromatography–mass spectrometry was applied to the aromas analysis of baijiu (Chinese liquor). RESULTS: Based on the results of optimization, a total of 76 volatile compounds were identified from 14 Chinese liquors, including 25 esters, 10 alcohols, 9 aldehydes and ketones, 8 aromatic compounds, 5 furans, 3 nitrogen‐containing compounds, 6 acids, 4 phenols, 3 terpenes, 1 sulfide‐containing compound, 1 lactone, and 1 acetal. By principal component analysis based on quantification results, 14 Chinese liquor samples could be classified into three groups. CONCLUSION: SBSE is a fast, simple, effective, and reliable method for extracting volatile compounds from Chinese liquor. The chemometrics approach revealed that LJ liquor with soy sauce aroma could exhibit more prominent sauce flavor through extending the time of storage, and its peculiar manufacturing practice was responsible for the soy sauce flavor.

小曲清香型白酒中关键风味成分分析

采用气相色谱-质谱-嗅闻分析、顶空固相微萃取-气相色谱-质谱联用技术对不同质量等级的小曲清香型白酒样品进行全面定性与定量分析,明确不同质量等级小曲清香型白酒的关键性风味成分,继而利用多元统计学方法对2种小曲清香型白酒进行差异性分析。结果显示,2种质量等级的小曲清香型白酒中挥发性香气成分在种类方面具有一定的相似性,但乙酯类风味成分在优级酒中的风味贡献度大于一级酒,而部分高级醇类、硫化物、醛酮类、呋喃类等成分在一级酒中的贡献大于优级酒。基于偏最小二乘判别分析,乙酸乙酯、乳酸乙酯、异丁醇、异戊醇、乙醛等化合物含量在2种不同质量等级小曲清香型白酒中存在显著差异,这也是导致二者感官评价和风味特征存在显著差异的关键因素。     

不同贮酒容器对凤香型白酒风味物质的影响

为探索贮酒容器对凤香型白酒风味物质的影响,采用气相色谱法、顶空固相微萃取及气相色谱-质谱联用法和超高效液相色谱法,以新酒为对照,对酒海贮酒、陶坛贮酒、不锈钢罐贮酒及对照4种酒样的风味物质进行分析。结果鉴定出酯类、醇类、酸类、醛酮类和酚类5类组分;其中,新酒的风味物质种类最少,其总质量浓度最高（79种、7 756 mg/L）,酒海贮酒的风味物质种类较多,但其质量浓度最低（94种、4 276 mg/L）,而陶坛和不锈钢罐贮酒种类最多,均为96种;其总质量浓度低于新酒而高于酒海贮酒（分别为5 957 mg/L和5 360 mg/L）。主成分分析及热图分析结果表明,不锈钢罐和陶坛贮酒在异戊醇、异丁醇、月桂酸乙酯、己酸-2-苯乙酯、己酸糠酯和乙缩醛等物质上具有较高的相关性,呈花香和果香的特征;酒海贮酒在十八酸乙酯、亚麻酸乙酯、苯乙醇和苯甲醛等物质上具有较高相关性,呈果香、甜香、蜜香和杏仁香特征。贮酒容器对贮酒中风味物质的影响可能与贮酒容器的透气性、释放过渡金属离子的性能以及对贮酒pH值的影响有关。     

定量评价小曲清香型白酒典型感官特征的研究

为了定量评价小曲清香型白酒的感官风格特征,从而更好地进行产品质量的控制,参照国外酒类风味轮建立的方法,同时结合现有白酒风味研究,对36个不同生产日期的不同质量档次和风格的小曲清香型白酒进行感官定量评价,利用统计分析软件对小曲清香型白酒的典型感官特征进行识别和提炼,筛选出代表小曲清香型白酒感官特征的描述语,包括29个香气...     

Sesame flavour baijiu: a review

Sesame flavour baijiu is an important style of Chinese liquor (Baijiu). However, the characteristic flavour substances of sesame flavour baijiu and associated microbial metabolic mechanisms are unclear. In recent years, research on sesame flavour baijiu has grown. This review focuses on current studies on the brewing process, the diversity of microorganisms involved in fermentation and the important aroma compounds in sesame flavour baijiu. This review will be helpful in understanding the brewing process of sesame flavour baijiu, but also in highlighting measures for improving quality. © 2020 The Institute of Brewing & Distilling     

酚类对酒的风味影响及白酒酚类控制策略

酚类物质是存在于大部分酒中的风味物质,对酒风味品质控制具有重要意义。酒体中的酚类物质组成及含量存在很大区别,本文对酒中酚类物质的来源、含量、化学组成对酒品质的影响及控制策略进行综述,为研究白酒酚类差异的产生原因及控制方法提供思路。
