Abstract Proteinase inhibitory activities of a number of finger millet and five representative varieties of other millets were determined. Inhibitory activities in the buffer extracts of the millets varied widely. Trypsin inhibitory activity (TIA) was more pronounced than the chymotrypsin inhibitory activity (CIA) in all the finger millet varieties tested. On germination, TIA and CIA were markedly reduced in the endosperm, but in the axis considerable TIA remained while CIA disappeared. Proteinase inhibitors of finger millet were found to be heat‐labile under neutral conditions and comparatively heat‐stable under acidic conditions. These studies suggest the presence of multiple forms of protein proteinase inhibitors in finger millet.
