However, large amounts of soy hulls are currently either underutilized or discarded as an agricultural waste, causing considerable waste disposal costs and possible environmental issues (Alemdar & Sain, 2008; Crandall & McCain, 2000).
Conversely, several soy by-products generated from soybean oilproduction, such as soy protein isolates, concentrates, grits, and textured, have been extensively used in processed foods as an emulsifier, extender, and binder (Jiang & Xiong, 2013; Lusas & Riaz, 1995). However, soy hulls have received very little industrial attention for practical use as a food ingredient.
