The combination of b-oligosaccharides from enzymatically hydrolysed barley b-glucan has attracted interest recently due to its positive effects on human health. This study aimed to assess the impact of the
endo-b-1,3-1,4-glucanase enzyme from Bacillus subtilis 168 on improving the nutritional and bioactive
properties of barley b-glucan. A new procedure for the isolation of b-glucan was developed, at a lower
temperature (45 °C), enabling purity from starch contamination, without affecting the yield (6 g b-glucan
from 100 g of barley flour). The endo-b-1,3-1,4-glucanase is cloned into E. coli pQE_Ek enables the high
production and purification (82% yield, 1.8 mg mL 1 and 440 U mg 1
) of an enzyme identical to the
natural one (25.5 kDa). The enzymatic reaction showed high efficiency of b-glucan degradation by recombinant enzyme, giving a mixture of products (of which 3-O-b-cellobiosyl-D-glucose and 3-O-b-cellotriosylD-glucose are the most abundant), the reduction of viscosity (17%)... and increase in antioxidant capacities
by 15.2%, 30.9% and 44.0% assessed by ABTS, DPPH and ORAC, respectively. These results indicate
the possible application of endo-b-1,3-1,4-glucanase enzyme in improving the properties of barley bglucan used as functional foods.
