This study innovatively proposes a feature fusion technique to determine fatty acid content during rice storage. Firstly. a self-developed olfactory visualization sensor was used to capture the odor information of rice samples at different storage periods and a portable spectroscopy system was employed to collect the near-infrared (NIR) spectra during rice storage.
