Inherent fluorescence imaging of target food products. Produce samples were layered to a thickness of 10mm and placed onto glass slides. Whole meat samples cut to a thickness of 10mm were similarly placed onto glass slides. 10mm thick ground meat samples were prepared using a doctor's blade deposition strategy to ensure homogenous thickness. Samples were imaged using a Nikon Ti-2 inverted microscope at excitation and emission wavelength pairings of 350 nm/470 nm, 490 nm/525 nm, 557 nm/576 nm, and 649 nm/666 nm. All images were taken at an exposure time of 300ms. Mean intensity was calculated for each collected image, and a minimum of ten images were taken for each sample. Average intensities provided for each food product were derived from samples sourced from multiple grocery stores.
