The diastatic activity of three sweet potato varieties was principally due to \-amylase. Substitution of sorghum malt with sweet potato at 20% (w/v) gave a higher activity than an all-sorghum malt. Maltose in the sorghum/potato wort was 50 mg/ml, similar to that in barley malt. The free alpha amino nitrogen of the sorghum/potato worts was lower than that of(More)
The endosperm cell walls of barley are degraded extensively during malting whilst those of sorghum are not. Malting barley produced endo-β-1,3:1,4-glucanase, endo-β-1,3-glucanase and pentosanase in large quantities. In contrast, malting sorghum developed mainly endo-β-1,3-glucanase and pentosanase. Although the limited break-down of the endosperm cell walls(More)
The diastatic power of four 'improved' Nigerian sorghum cultivars was produced principally by α-amylolytic activity, unlike that of Nigerian Proctor barley which came principally from β-amylolytic activity. Free amino nitrogen levels and extracts of the sorghums were higher than those of barley when the sorghum was mashed in a modified procedure in which(More)
