藏药奶制南寒水石X-射线衍射指纹图谱及其在微波炮制中的应用

Fingerprint of X-ray diffraction of Tibetan medicine dairy Nanhanshuishi and its application in processing by microwave

利用粉末X-射线衍射分析法,在采用MATLAB软件计算共有峰相似度的基础上,建立了常规奶制南寒水石的特征指纹图谱,并通过X-射线衍射分析和人工胃液钙溶出率的比较,探索微波奶制新工艺的可行性。结果表明,常规奶制南寒水石X-射线衍射指纹图谱相似度均达到95%以上,建立的X-射线衍射特征指纹图谱专属性强,可为其质量评价提供依据;此外,微波奶制品与常规奶制品相似度良好,其中微波处理15 min效果最好,微波奶制法可以代替传统方法。

The characteristic fingerprint of conventional dairy Nanhanshuishi was established by X-ray diffraction （XRD）, based on similarity of caculation on public peaks by MATLAB software, and the feasibility of new dairy technology of microwave method was explored between XRD and the dissolution rate in artificial simulation gastric juices. The result showed that similarity of shared peak in XRD of conventional dairy Nanhanshuishi was 〉 95%, This XRD characteristic fingerprint of conventional dairy Nanhanshuishi had strong specificity, could be used to provide a reference for identification and quality evaluation. This study also showed that the similarity of microware dairy products and conventional dairy products was good, and the sample of microwave 15 min was the best, and new dairy method by the microwave could replace the traditional method.
