Abstract
Abstract Food compositions are prepared incorporating an alkaline peroxide-treated conversion product of a nonwoody, lignocellulosic substrate. In a ruminant system, the conversion product serves as a highly digestible carbohydrate source. When added to foods intended for consumption by humans and monogastric animals, the conversion product functions as a natural source of dietary fiber and a noncaloric substitute for cereal flour or other amylaceous materials. It is also useful as an extender and promoter of functional properties in doughs and batters.
