Zusammenfassung:The invention provides a method for studying an effect of a grinding particle size on Raman spectrum of rice and relates to the technical field of rice detection. The method for studying the effect ofthe grinding particle size on the Raman spectrum of the rice comprises the steps of material preparation, sample preparation, spectrogram testing, data analysis, result and analysis, uniformity analysis of ground rice, Raman spectrum analysis and promotional analysis. The rice is ground and screened to prepare rice flours with different grinding particle sizes; and the effect of the grinding particle size on the Raman spectrum is researched to indirectly investigate the uniformity of the rice flour at each grinding particle size in order to provide stable and reliable data source for follow-up establishment of a rice origin distinguishing model. 粉碎粒度对大米拉曼光谱影响的研究方法,本发明涉及大米检测技术领域。它的研究步骤如下:材料准备;样品制备;谱图测试;数据分析;结果与分析;粉碎后大米均匀度分析;拉曼光谱谱图解析;推广性分析。对大米进行粉碎及筛分处理,制成不同粉碎粒度的米粉,探究粉碎粒度对拉曼光谱的影响,间接考察每种粉碎粒度下米粉的均匀性,旨在为后续建立大米产地鉴别模型提供稳
