Bio-based fiber gums (BFGs) and Z Trim are water soluble arabinoxylan (Hemicellulose B) and water insoluble fibrous cellulose rich arabinoxylan respectively, isolated from various low value agricultural residues (corn stover, wheat straw, etc.), agricultural processing by-products (corn fiber, wheat bran, rice fiber, sorghum bran, sugar cane bagasse, etc.) and energy crops (switch grass and miscanthus) by alkaline treatment. The BFGs, isolated from different agricultural materials are purified, characterized and their functionalities are studied. They appear to have useful properties as emulsifiers, antioxidants, dietary fibers and other food ingredients. Like corn fiber gum (CFG), these polysaccharides are unique in making low viscosity solutions, even at high concentrations. Z Trims, prepared from the residues left over after BFG isolation, are also characterized and their water holding capacity, rheological behavior and ORAC values are determined. The rheological studies of these gels show that they make very viscous gels at low concentrations in water. They are completely non-digestible to humans and therefore make an excellent non-caloric food bulking agent and become helpful in replacing fat with healthy fiber and water without changing taste but improving mouth feel. Due to their high water absorbance, fiber addition, oil emulsification, and the reduction of calories, cholesterol, trans-fat and saturated fat, they become very useful ingredient in bakery products, dairy products, meats, dressing, mac and cheese etc. Understanding the functional properties of BFG and Z Trim will be beneficial from their commercialization point of view for their use in food industries.
