Abstract:
Multi-hydrogen peroxide process can improve all physical properties of rice straw. Rice straw quantity of 0.2% (w/v) provided maximum values of cellulose content, brightness, water holding capacity, and oil-binding capacity of prepared cellulose. The smallest particle of prepared cellulose (less than 0.075 mm) had less water holding capacity, oil binging capacity, redness (a*) than the biggest particle size (0.3-0.5 mm) while the smallest particle had more lightness (L*) than the biggest particle. An additional 5% of the smallest prepared cellulose particle gave the highest doughnut quality. Finally, the smallest particle size of cellulose with the increasing of water content from 50 to 60% of flour weight.Consumers scored the doughnut made by 10% of the smallest particle addition favorable when water was added at 60% of flour weight
