摘要：
A method for production of an animal feed product comprises: a) partial hydrolysis of a fermentation feedstock or the non-ethanol by-product of a fermentation process such as stillage, wherein the partial hydrolysis converts non starch polysaccharides to soluble oligomers and monomers, b) fermentation of the soluble oligomers and monomers in the partially hydrolysed feedstock or non-ethanol by-product to produce ethanol, c) recovery of the non-ethanol by-product from the fermentation of step b) to produce an animal feed product. In addition a method of producing an animal feed product comprising partial hydrolysis of the non-ethanol by-product of a fermentation process performed on a fermentation feedstock, and recovery of the partially hydrolysed product is described. An animal feed product produced as a byproduct of a fermentation product comprising less that 10% by weight hemicelluloses or 5% by weight pentose sugars is also disclosed. The methods produce an animal feed product with improved nutritional content by virtue of decreased levels of pentose sugars, increased relative protein concentration, decreased relative fiber concentration, decreased levels of soluble oligomers and monomers or decreased levels of reducing sugars.
