Brazilian hull-less and malting barley genotypes: I. Chemical composition and partial characterization

Barley represents an important source of total dietary fiber (TDF) and β-glucans. The chemical composition and partial characterization of two Brazilian barley experimental lines, hull-less and malting, are reported. The range in diameter of the A- and B-type granules was similar in both barley lines, 15 to 28 μm and 8 to 10 μm, respectively. Higher values for total starch, damage starch, ash, TDF and insoluble dietary fiber (IDF) were observed in the malting line while μ-glucan content was similar in both samples. The malting barley line had higher values of total isolated starch, as well as residual protein and total lipids in starch. The starch from the hull-less barley line had lower swelling power and higher solubility than malting barley.
