近红外光谱法在卷烟糖料质量稳定性控制中的应用

 为了能够快速无损地控制卷烟糖料质量的稳定性,应用傅立叶变换近红外(FT-NIR)光谱分析技术结合相似度匹配的定性分析方法,以来自红云红河烟草(集团)有限责任公司云烟(软珍品)、云烟(紫)和云烟(红)3个牌号糖料样品各20批的近红外透射光谱数据为基础,利用TQ统计软件分别建立以上牌号糖料的相似度匹配模型,并对建模参数和模型的预测效果进行了评价.结果表明,云烟(软珍品)、云烟(紫)和云烟(红)3个牌号的糖料模型对模型样品预测的相似度匹配值(SMV)均在95以上,而对非模型样品预测的SMV均非常低,说明若糖料质量发生变化,就可以通过近红外光谱分析技术结合相似的匹配分析很好反映出来.因此,应用FT-NIR光谱分析技术可以对卷烟糖料进行快速、无损和大批量的检测,为卷烟糖料的质量稳定性控制提供了新的思路和方法.

Application of the NIR spectroscopy to the control of the qualitative stability of tobacco casing material

In order to control the qualitative stability of tobacco casing material,the authors suggested the application of FT-NIR Spectroscopy combining with the qualitative analysis method of similarity match.In this research,similarity-match identifying models were established respectively using the TQ statistical software based on the NIR transmission spectra of 20-batche-cigarette casing material samples of 3 brands,Yunyan (Soft Rarity),Yunyan (Purple) and Yunyan (Red),from Hongyun Honghe Tobacco (Group) Co.,Ltd.Established parameters and the identifying effects of the models were evaluated in this study as well.Results showed that the Similarity Match Value ( SMV ) of model samples by the models of 3 brands,Yunyan (Soft Rarity),Yunyan (Purple) and Yunyan (Red),were more than 95;while of the non-model samples were very low.It shows that the application of FT-NIR Spectroscopy,with combining the qualitative analysis method of similarity match could recover the quality changes of cigarette casing material.Therefore,the application of FT-NIR Spectroscopy could identify the tobacco casing material rapidly,nondestructively and largely,and it provided new ideas and methods to control the qualitative stability of the tobacco casing material.
