摘　　要：目的采用近红外光谱方法定性鉴别珍珠粉真伪。方法利用近红外漫反射光谱技术结合相似度匹配和判别分析贝壳粉,牡蛎粉、石决明粉、滑石粉,纳米碳酸钙和珍珠粉定性鉴别。结果珍珠粉相似度匹配值为93~97,贝壳粉为77~87,其余粉小于50。结论设定90作为珍珠粉的相似度匹配阈值可以定性鉴别真伪珍珠粉。AIM To qualitatively identify the authenticity of pearl powder by near-infrared spectroscopy METHODS Near-infrared diffuse reflectance spectroscopy in combination with similarity match and discriminant analysis was used to distinguish peal powder with the powders of shell, oyster, abalone, talc and nano calcium car- bonate. RESULTS Similarity match value was in the range of 93 to 97 for pearl powder, of 77 to 87 for shell powder, and of less than 50 for the rest powders. CONCLUSION This research provides a threshold of 90 for the identification of the authenticity of pearl powder.
