Differences in ratio of carbon stable Isotopes among barley grain milling fractions with various concentrations of beta-glucans [Elektronski vir]Levanič, Tom ...The grains of three barley varieties were milled and sieved to obtain respective milling fractions with a content of beta-glucans (b-G) from 1.4 to 10.7%. The enriched fraction obtained by the ... extraction and precipitation contained 24.7% of b-G. The differences between the ratio of stable C carbon isotopes were established. Milling fractions with coarse particles had more beta-glucans and a more negative ratio of δ 13C isotope in comparison to the respective intact barley grain. However, the enriched fraction had a less negative isotope ratio. So, it is not expected that the deviation from the stable isotope ratio of grain in milling fractions is the result of the content of b-G, but it depends on other barley grain constituents. In different parts of barley grain, there are substances with different stable isotope ratios, and by milling and sieving, they are assorted to the same milling fraction with most of the b-G. The method for determining the ratio of a stable carbon isotope in diverse barley grain fractions, applied in this investigation, is potentially opening the possibility for an additional method of screening the concentration of bioactive constituents in barley grain.Source: Molecules [Elektronski vir]. - ISSN 1420-3049 (Vol. 28, article no. 5738, 2023, str. 1-8)Type of material - e-articlePublish date - 2023Language - englishCOBISS.SI-ID - 160452867
