  The objective of this study was to evaluate the chemical,   physicochemical, and functional properties of agrowastes derived   from okara (Glycine max), corn cob (Zea mays  sp.), wheat straw (Triticum sp.), and rice husk   (Oryza sativa) for potential applications in foods. The   fibrous materials (FM) were treated with alkali to yield fibrous   residues (FR). Rice husk contained the highest ash content (FM,   8.56%; FR, 9.04%) and lowest lightness in color (FM, 67.63; FR,   63.46), possibly due to the abundance of mineral constituents.   Corn cob contained the highest amount of soluble dietary fiber   (SDF), whereas okara had the highest total dietary fiber (TDF).   The high dietary fiber fractions of corn cob and okara also   contributed to the highest water- and oil-holding capacities,   emulsifying activities, and emulsion stabilities for both FM and   FR samples. These results indicate that these agrowastes could be   utilized as functional ingredients in foods.
