where the nitrogen content is multiplied by a factor of 6.25 to give protein content. From each sample, 0.5 g mucilage powder was digested at 400 °C in a digester using 6 ml mixture of sulfuric acid and orthophospheric acid (100:5) in the presence of 0.5 ml selenium and 100 ml potassium sulphate. The solution was then distilled with sodium hydroxide (added in small quantity) which converts ammonium salt into ammonia. The ammonia was trapped using 1% (v/v) boric acid and titrated using 0.1 N HCl solution until end point was reached. Both distillation and titration and with subse-quent determination of nitrogen and protein content were automatically done by the Microkjeldahl apparatus. Protein contents recorded are averages of three determinations.
