Detection of Rice Prolamin and Glutelin Content Using Hyperspectral Imaging Combined with Feature Selection Algorithms and Multivariate Regression Models

Prolamin and glutelin are the major constituents of rice protein. The rapid and non- destructive detection of prolamin and glutelin content is conducive to the accurate assess- ment of rice quality. In this study, hyperspectral imaging combined with regression models and feature wavelength selection was employed to detect the rice prolamin and glutelin content. Feature wavelength selection was achieved using the successive projections algo- rithm (SPA), competitive adaptive reweighted sampling...
