Effects of Growth Stage and Particle Size on the Physical, Chemical, Structural, and Bioactive Properties of Alkaline-Extracted Dietary Fiber from Rice Husk (Oryza sativa L.)
Experimental analysis shows how growth stage and particle size affect dietary fiber properties, indicating the potential of rice husk as a functional ingredient.
Key Points
Fiber from green rice husk shows greater bioactive compound content than that from ripe rice husk.
Cellulose content varied significantly, reaching up to 85 g/100 g dry weight in green rice husk.
Reducing particle size improved the water- and oil-holding capacities of dietary fiber up to five-fold.
The different growth stages of rice husk influence the functional properties of dietary fiber extracted.
