The application of UV-VIS-NIR spectroscopy combined with multivariate analysis for the classification and identification of buckwheat groats was analyzed. Samples of buckwheat groats differing in harvest time, kernel size, roasting method, and storage time were divided into groups using a cluster analysis method. The principal components method revealed absorption bands in UV-VIS-NIR spectra corresponding to functional groups of the composition components and contributing most to differentiation of the samples into buckwheat quality categories. Discriminant analysis confirmed a hypothesis on dividing the buckwheat samples into groups and formulating a classification function to identify and sort buckwheat groats.
