摘　　要：该文以"互助"青稞酒为研究对象,研究了基于紫外光谱法的"互助"青稞酒快速鉴别方法。在对光谱进行适当预处理的基础上,通过比较样品紫外光谱与参照光谱的夹角余弦、相关系数以及紫外相似度等相似性评价指标,构建了该品牌青稞酒的质量控制图。将"互助"青稞酒、其他品牌青稞酒和非青稞原料白酒样品的紫外光谱与参照光谱比较,结果表明,"互助"青稞酒样品均处于质量控制图的控制上、下限之间,而其他两类样本均位于控制下限以下。该方法可为"互助"青稞酒品质保证提供一种简单、快速的鉴别方法。The‘Huzhu’brand Qingke liquor was taken as the research object,and the rapid identification methods of ‘Huzhu’brand Qingke liquor based on UV spectroscopy was studied. On the basis of proper pretreatment of the spectrum,by comparing the similarity evaluation indexes,such as the angle cosine,correlation coefficient and UV similarity,between the ultraviolet spectrum of the sample and the reference spectrum,the quality control chart of ‘Huzhu’brand Qingke liquor was constructed. The spectra of ‘Huzhu’Qingke liquors,other brand liquors and non-Qingke liquors were compared with the reference spectrum,as results,all the ‘Huzhu’Qingke liquors were kept between the upper and lower control limits of the quality control chart,and the other two classes of samples were located under the lower control limit. The results indicated that this proposed method could be used as a simple and rapid identification method for quality assurance of ‘Huzhu’brand Qingke liquor.
