Abstract
Systems and methods for material analysis are disclosed in which an organic sample (e.g., a foodstuff, tissue sample or petroleum product) is illuminated at a plurality of discrete wavelengths which are absorbed by fatty acid and fatty acid oxidation products in the sample. Measurements of the intensity of reflected or absorbed light at such wavelengths are taken, and a analysis of absorbance ratios for various wavelengths is performed. Changes in the reflection ratios are correlated with the oxidative state of fatty acids present in the material.
