ATR‐MIR: A valuable tool for the rapid assessment of biochemically active compounds in grains

Given the high production and consumption rates of grains worldwide, rapid methods for the assessment of their biochemical composition would be of great usefulness for researchers, producers and consumers alike. Here, we report on the usefulness of attenuated total reflectance mid‐infrared spectroscopy (ATR‐MIR) for detecting and quantifying biochemically active constituents in Australian grains and pulses. Chemometric techniques such as principal component analysis (PCA) and partial least squares (PLS) regression show promise for predicting protein, total phenolic, monomeric anthocyanin and total antioxidant capacity in wheat. In the future, similar non‐invasive techniques for biochemical analysis may be utilised by all stakeholders in view of providing equitable premiums for grain crops with high levels of nutritionally and medically beneficial phytochemical compositions.   (17) (PDF) ATR-MIR: a valuable tool for the rapid assessment of biochemically active compounds in grains.
