The content of vitamine E in hop cones of the Saaz variety

Abstract

The activity of vitamin E, total content of tocols and the content of individual isomers: α-tocopherols, β-tocopherols, γ-tocopherols and δ-tocopherols was monitored in samples of hop cones of the world-important Saaz variety. Hop cone samples originated from hop-breeding area Tršice, Czech Republic. The method used for the determination of vitamin E in barley was modified and used for this quantitative analysis. The results indicate that monitored characteristics are influenced by the year of harvest (2010 or 2011) but also by the age of hop-gardens (hop bucks). High values of vitamin E activity (up to 67.79 mg.kg−1) and total content of tocols (up to 76.31 mg.kg−1) in hop cones are worth further attention from the viewpoint of alternative use of hops.
