Sažetak
The cultivar and environmental variations of β-glucan content in grains and malt and malt β-glucanase activity were investigated in 6 barley cultivars grown in two different environments. Three winter cultivars (Zlatko, Barun and Vanessa) and three spring cultivars (Fran, Matej and Scarlett) were collected from experimental fields of the Agricultural Institute Osijek. Prior to micromalting the barley samples were analyzed for crude protein content by NIT method and β-glucan content. Grain protein content varied from 9.93% to 11.60%, and β-glucan content varied from 3.5% to 6.0%. Malt analyses were done according to the EBC official methods and the following parameters were determined: malt extract content, extract difference between fine and coarse grind malt, viscosity, friability, β-glucan content in malt and malt β-glucanase activity. A significant differences were found among winter and spring cultivars in extract difference, viscosity and friability, while statistically justified difference in malt extract content among winter and spring cultivars was not observed. The cultivar and environmental variations of β-glucan content were much higher in malt than in grains. Regarding malt β-glucanase activity, the significantly higher activity was found in spring cultivars, in contrast to winter cultivars.
