Abstract: The present invention generally relates to methods and systems to determine the properties of light-matter interaction in the characterization of food materials using an incident light source and a sensor to measure the opto-magnetic properties of light reflected from the food material. The opto-magnetic properties can be used to generate an opto-magnetic footprint. Comparison of the opto-magnetic footprint with opto-magnetic footprints of known materials enables characterization of the food materials. This enables detection of pesticide residues, confirmation of “organic” labeling, and determination of freshness of the food materials.
