The determination of swelling power and solubility (Modified from Schoch, 1964)
Each flour sample (1 gram) was mixed with 15 ml distilled water and then heated at 95°C in
water bath for 30 minutes. The sample was centrifuged at 2,200×g for 15 minutes. The supernatant was
carefully poured in weighed aluminum can and then weighed the precipitated. The supernatant in
aluminum can was dried at 100°C for 3 hours in hot air oven and then cooled in desiccators for 30
minutes. The dried solid in aluminum can was weighed and then calculated for solubility and swelling
power by following equations:
