Abstract

Abstract: There is no data on the lipid profile of Fagopyrum tataricum grain and its milling products. Therefore, we aimed to assess the phytosterol and tocopherol content and fatty acid profile of the samples of F. tataricum . Grain was milled, then the milling product separated to hull, bran, and two flour fractions, differing in particle size. The highest level of lipids (total fatty acids – 83%, with dominant oleic acid – 40%) was observed in the bran fraction (380 μm > GA > 180 μm). All samples contained some natural cis fatty acids, such as vaccenic acid (C18:1 n-7; ~2.8%) and tocopherol (α-, β-, δ- and γ-tocopherol). The highest content of total tocopherol was also detected in the bran fraction (0.1% of lipids). The content of lipid soluble bioactive substances was different and depended on the size of obtained fraction, therefore properly designed grain processing technology can be used to produce food with high nutritional value. Graphical abstract: Image 1 Highlights: Biological value of lipids depend on used F. tataricum grains separation technique. The ground grains fraction contains lipids of different fatty acids profile. Separation technique differentiates sterols and tocopherols content in samples. The lipids of fraction 380 μm > GA > 180 μm characterize by the highest nutrition value.
