Resumen : Seventy barley accession from Ecuador were analyzed to determine the content of mixed linkage βglucan. Twelve of these materials presented a higher content than the population average 2.10% (w/w) and were selected to determine the relationship among β-glucan, viscosity and dietary fiber, as well as the effect of scarification, cooking, roasting and malting in its content. In the 12 accessions the content of βglucan showed a high degree of correlation (r = 0.86) with soluble dietary fiber but low correlation with viscosity (r = -0.17). In most accessions, β-glucan increased in roasted or scarified grains. The roasting process increased the content by 35.51% (w/w) and scarification by 26.53% (w/w). Cooking decreased content by 39.92% and malting by 77.90%. The megazyme kit was used to determine the content of (1→3) (1→4) -β-D-glucan (Mixed-linkage). Results of this study show that Ecuadorian barley genotypes with a β-glucan content greater than 2.10% are suitable for human consumption and those with lower value than the indicated are suitable for the beer industry.
