中文摘要:

      目的 建立一种基于紫外光谱相似度质量控制图技术的威士忌真假鉴别方法。方法 选取具有代表性的苏格兰威士忌真酒样—芝华士12年威士忌作为研究对象, 采用紫外光谱扫描采集真酒样品吸光度数据, 将数据进行统计分析, 绘制紫外光谱相似度质量控制图, 并运用质量控制图模拟识别未知样品, 考察方法对未知样品真假鉴别的效果。结果 模拟识别10批次未知样品, 真酒样紫外光谱相似度均处于质量控制图的控制下行动限以上, 而假酒样品紫外光谱相似度均位于下行动限以下。结论 该方法快速、简单、准确, 可以为威士忌的真假鉴别提供参考。

英文摘要:

      Objective To establish a method for the identification of whisky true and false by quality control chart based on the similarity of ultraviolet (UV) spectrum. Methods CHIVAS REGAL AGED 12 YEARS, a representative real Scotch whisky sample, was selected as the research object. The absorbance data of real Scotch whisky samples were collected by UV spectrum scanning, and the data were statistically analyzed to draw a quality control chart of UV spectrum similarity. The quality control chart was used to simulate the identification of unknown samples, and the effect of the inspection method on the identification of unknown samples was investigated. Results Totally 10 batches of unknown samples were identified by simulation. The UV spectrum similarity of real samples was above the lower action limit of the quality control chart, while the UV spectrum similarity of fake samples was below the lower action limit. Conclusion This method is fast, simple and accurate, which can provide reference for the true and false identification of whisky.
