ABSTRACT
Chemical and biological methods were used to determine the nutritional value of three recently
developed strains of hulless barley compared with a commercially grown hull-containing cultivar in
Poland. The following quality criteria were used: protein content and composition, dietary fibre (DF)
and non-cellulose polysaccharides (NCP), protein (TD) and dry matter digestibility (DMD) as well as
biological value (BV) and protein utilization (NPU) in rats. All tested hulless barleys had higher
protein contents (15.3 vs 13.4%) but lower lysine concentrations in their protein (2.86 vs 3.14) than
the hull-containing one. The lack of hulls in barley resulted in lower insoluble dietary fibre (IDF) and
insoluble arabinoxylan contents (by 44 and 41%, respectively) and in a higher soluble β-glucan (by
58%) content. In rats, TD and DMD were positively correlated with protein content (r = 0.80 and
0.78) and negatively with IDF content (r = -0.75 and -0.95). It seems, therefore, that the nutritive
value of hulless barleys was distinctly better than that of the hull-containing cultivar.
