Discriminant analysis of Olomouc curd cheese by Fourier transform near infrared spectroscopy
ripening Mahalanobis distance
2014/3/28
We used the discriminant analysis of curd cheese during storage by Fourier transform near infrared spectroscopy method (FT-NIRs). Olomouc curd cheese samples were stored at 5 and at 20°C during seven ...

Spectroscopy of UV-VIS-NIR combined with chemometric analyses was used as a non-destructive technique to build models for the quantitative characterisation of the main compounds of wine. The work in m...
不同贮存温度蜂花粉的可见-近红外光谱鉴别（Application of Visible/Near Infrared Spectroscopy for Discrimination of Bee Pollen under Different Storage Temperature）
可见-近红外光谱技术 蜂花粉 贮存温度
2009/11/3
利用可见-近红外光谱技术结合最小二乘支持向量机（LS-SVM）对不同贮存温度下的蜂花粉进行鉴别。选择-20、4、15、25和40℃ 5个温度下分别贮存60d后的蜂花粉为研究对象。对原始光谱数据进行平滑和附加散射校正（MSC）的预处理后进行主成分分析，选择4～20个主成分作为输入变量进行LS-SVM建模。模型预测参数比较结果显示，当主成分数取20时模型的预测效果最好，预测相关系数r2p≥0.9919...
