Scan Reveals Nutrient Content of Produce

Texas A&M AgriLife Research scientists have determined that produce can be scanned for nutrient content using a handheld Raman spectrometer. In their study, the team scanned corn kernels and were able to calculate levels of protein, carbohydrates, fiber, and carotenoids quickly and without destroying the sample. The technology could be used to assess qualities of grain in the field, and the same scan can help identify diseases in plants even before symptoms appear.
