2.2 Water hydration property
the hydration property of flour-hydrocolloids mixtuer were investigated according to the modified method of Lee and Inglett (2006). The hydration properties were determined by mixing three flours with each of the hydrocolloids at two levels (2% and 4%), and the hydration properties of the flours were also assessed in the absence of hydrocolloids.After mixing each sample (0.25 g), the room temperature for 30 min before centrifuging (718 x g,30 min).The supernatant was then dried in a 105 C oven until a constant weight was reached and
