摘要
为促进白酒酿造行业的大宗副产物——酱香丢糟的有效利用,本研究以贵州祥康酒业(集团)有限公司和贵州国台酒庄有限公司12个酱香丢糟样品为研究对象,对其理化指标(水分、淀粉、还原糖、酸度)进行测定,并采用紫外分光光度法,以芦丁为标准物质建立标准曲线,对其总黄酮含量进行测定.结果表明,酱香丢糟样品中水分、淀粉、还原糖、酸度较稳定,总黄酮平均含量为 0.012 g·L-1;本研究中采用紫外分光光度法测定样品中总黄酮含量,操作简单、结果准确可靠,适用于酱香酒糟中总黄酮的定量测定,可为酱香酒糟的深度开发利用提供依据.
Abstract
In order to promote the effective utilization of Jiangxiang Baijiu spent grains,a major by-product of liquor brewing industry,this study took 12 Jiangxiang Baijiu spent grains samples from Guizhou Xiangkang Liquor(Group)Co.,Ltd.and Guizhou Guotai Winery Co.,Ltd.as the research objects,and determined their physical and chemical indicators(water content,starch,reducing sugar,acidity),and used UV spectrophotometry to establish a standard curve with rutin as the standard substance to determine the total flavonoid content.The results showed that the moisture,starch,reducing sugar and acidity in the Jiangxiang Baijiu spent grains samples were relatively stable,and the average content of total flavonoids was 0.012 g·L-1.In this study,the UV spectrophotometry method was used to determine the total flavonoid content in the samples,which was simple to operate and the results were accurate and reliable.It is suitable for the quantitative determination of total flavonoids in Jiangxiang Baijiu spent grains,and provides a reference for the in-depth development and utilization of Jiangxiang Baijiu spent grains.
