通过毛细管柱-直接进样法测得白酒中醇类、酸类、酯类、醛类、吡嗪类等70余种组分及含量,通过阈值转化为香气活力值(odor activity value)后,将OAV高的物质确定为香型白酒的关键香气组分。将白酒中组分分类成酯类、酸类、羰基化合物、醇类、杂环类物质,通过主成分分析探寻白酒中组分与香型、香型与香型之间的关联。
The Study of Chinese Liquor Flavor and Aroma Components
More than seventy components,including alcohols,acids,esters,aldehydes were detected in Chinese liquor using capillary column-direct injection.OAV were calculated by contents and thresholds.The components with high OAV were considered as the key aroma compounds.The principal component analysis based on esters,acids,aldehydes,alcohols,heterocyclic substances was used to establish the association of components and flavor and different flavors.
