通过多变量分析淀粉的荧光指纹判别类别

Currently, in fields including the food field, the study to apply a 3D fluorescence spectrum (fluorescence fingerprint), with a large amount of sample-specific numerical data, for the determination of agricultural product origins and the evaluation of grain powder types and grades is being conducted. 

In general, chemical analysis is used for the analysis of foods and agricultural products. However, the preparation is necessary and it takes a long time to analyze multi-specimens. 
On the other hand, the analysis by a fluorescence spectrometer, which provides a sample-specific fluorescence fingerprint, characteristically allows the direct measurement of a sample without any preparation. 

This time, the 3D fluorescence spectra of starches from different raw materials were measured by using this method and the types were determined. 

F-7000 Hitachi fluorescence spectrophotometer, because of the highest 3D fluorescence spectrum throughput for the instrument class (about 3 minutes under the analytical conditions used this time), is used for a broad range of applications from cutting-edge research to quality control.
