Rapid and Low-Cost Detection of Millet Quality by Miniature Near-Infrared Spectroscopy and Iteratively Retaining Informative Variables
Traditional chemical methods for testing the fat content of millet, a widely consumed grain, are time-consuming and costly.In this study, we developed a low-cost and rapid method for fat detection and quantification in millet.A miniature NIR spectrometer connected to a smartphone was used to collect spectral data from millet samples of different or
