Comparison of the mashing and brewing potentials of crude extracts of Abrus precatorius, Burnatia enneandra and Cadaba farinosa

  The mashing and brewing potentials of crude extracts of three plants commonly used in Northern Cameroon to make starch gruels sweet were assessed using sorghum cultivarSafrari as an adjunct. Alpha-amylase activities of the extracts fluctuated between 18 and 122 U/g, while the diastatic power and the β-carboxypeptidase activities ranged between 83 and 123 WK, and 16 and 63 mg FAN/min/µL,...
