Abstracts

Buckwheat (Fagopyrum esculentum) is a pseudocereal with extremely beneficial nutritional composition. High content of quality proteins, dietary fibers, polyphenolic compounds (especially rutin), as well as the absence of gluten, makes it very common in human and animal nutrition since ancient times. Thanks to its low glycemic index, content of resistant starch and fiber, as well as the presence of bioactive compounds that affect enzymes involved in carbohydrate metabolism, buckwheat shows a favorable effect on the glycemic response. The aim of this work was to examine the chemical composition and content of biologically active compounds in buckwheat seeds, as well as the effects of storage conditions on changes in the quality of buckwheat. The results showed an extremely high content of gallic and p-coumaric acids, as well as epicatechin (91, 102.4 and 95.7 µg/g DW, respectively). Storage conditions did not significantly affect the content of gallic and p-coumaric acids, while the content of epicatechin decreased with longer storage time. Also, the content of total phenols, as well as antioxidant activity decreased with increasing storage time compared to the native sample. The results of this research contribute to the promotion of buckwheat and buckwheat flour as an extremely important raw material and the possibility of its application in the modern food industry.
