Yellow Wine is China wine, its unique flavor, self style. With the people's material and cultural life level increasing, consumer demand for the products of wine also continue to improve and change, the nutritional value and taste of rice wine, especially the formation of a minor component of yellow rice wine flavor more and more get of consumer attention. Flavor Yellow Wine comment from a perceptual stage, including some general chemical group
Analysis of Tengzhou City Xiangying Technology Co., Ltd. to XiangyingGC7990plus static headspace gas phase chromatography of the sample volume, equilibrium temperature, equilibrium time and ionic strength influence factors of static headspace gas chromatographic determination of ester of aroma substances in yellow rice wine and determine the optimal analysis conditions for: equilibrium temperature of 50 DEG C, balance time of 20 min, sample amount 5 ml, NaCl was added 2 g. The method has good linear relationship in the range of mass concentration, and has good stability and high accuracy. It is a quantitative analysis of the aroma components in yellow rice wine by wine sample increment method. The results showed that ethyl acetate and ethyl lactate content will increase with the increase of aging time, vary butanol, isoamyl alcohol content is the opposite. Can be considered as one of the characteristics of alcohol ester ratio judgement on the basis of age and quality of the Yellow Wine.
黄酒是中国的国酒,它的香味独特,自成风格。随着人们物质文化生活水平的日益提高,消费者对黄酒这一产品的要求也不断提高和变化,黄酒的营养价值和口感,尤其是形成黄酒风味的微量成分越来越受到消费者的普遍重视。黄酒的风味物质品评已从一个感性阶段，包括笼统的部分化学组
滕州市翔鹰分析技术有限公司以XiangyingGC7990plus静态顶空-气相色谱法研究了样品量、平衡温度、平衡时间、离子强度等影响因子对静态顶空-气相色谱测定黄酒中香气物质酯的影响,确定***佳的分析条件为:平衡温度50℃,平衡时间20 min,样品加入量5 mL,NaCl加入量2 g。该方法在质量浓度范围内有良好的线性关系,且稳定性好、准确度高,采用酒样增量法对黄酒中香气成分进行定量分析。结果表明,乙酸乙酯、乳酸乙酯的含量随着陈酿时间的增加而提高,而异丁醇、异戊醇含量却与之相反。可以考虑将醇酯比特征作为黄酒酒龄和品质的判断依据之一。
