Problems solved by technology

However, there is still a potentially digestible fiber content in these materials (and other fibrous by-products of agricultural processing), which is not available to animals due to the partially insoluble and crystalline nature of such materials

[0034] definition

[0035] Before describing the present invention in detail, certain terms with ordinary meanings commonly understood by those of ordinary skill in the art are still defined herein in order to better distinguish the subtle differences in meanings designated by the inventors. It should be understood that the definition provided in the text is intended to include the general meaning understood in the art without limitation, unless the meaning is incompatible with the definition provided herein, in which case the definition provided herein shall prevail.

[0036] "Food fiber" means a naturally occurring substance derived from plant or microbial sources. This substance is mainly composed of carbohydrate polymers and can be fed to animals without causing disease. It is not digested by humans, but can be at least partially Digestion in monogastric and ruminant animals. Non-limiting examples of edible fibers include cellulose, hemicellulose, pectin, proteoglycan and the ...

Abstract

Disclosed herein are methods of treating an edible fiber source to make an animal feed with increased digestible energy. An exemplary method includes hydrolyzing the edible fiber source with an inorganic fiber hydrolyzing agent in a twin screw mixer that shears the edible fiber to a size of between 0.5 to 25 mm. The hydrolysis in the mixer occurs at pressure of about 14 psig or higher with a temperature about 1000C to 110 DEG C. The inorganic hydrolysis liberates a first portion of soluble carbohydrates from the edible fiber source. The inorganically hydrolyzed material is also treated (before or after) with a fiber degrading enzyme to solubilize a second portion of carbohydrates. The dually hydrolyzed material is dried to form an animal feed or feed ingredient having a soluble and insoluble carbohydrate fraction with the amount of soluble carbohydrate being at least 45% wt / wt of the total carbohydrates obtained from the edible fiber source.
