Embodiment 1

[0061] Acid hydrolysis and enzyme hydrolysis of thin stillage of embodiment 1

[0062] introduce

[0063] Thin stillage is obtained through a bioethanol process (Ensus). figure 1 Ensus and the point in the process where thin stillage is produced are shown. The percent moisture content (wt / wt) used for each step of the process is shown. Thin stillage is the semi-solid residue stream of the ethanol process, and it is obtained after removal of the wet cake from the residue. The thin stillage is expected to be free of starch and glucose, and the carbohydrates will be mainly residues of cellulose and hemicellulose. It is also expected that under optimal conditions its hydrolysis will release most of the sugars from these materials.

Abstract

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 performed on a fermentation feedstock, which 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; and c) recovery of the non-ethanol by-product from the fermentation of step b) to produce an animal feed product more specifically an animal feed product with improved nutritional content. A method for production of an animal feed product comprises: a) partial hydrolysis of the non-ethanol by-product of a fermentation process performed on a fermentation feedstock, which partial hydrolysis converts non starch polysaccharides to soluble oligomers and monomers; and b) recovery of the partially hydrolysed product from step a), to exclude the soluble oligomers and monomers, to produce an animal feed product, more specifically an animal feed product with improved nutritional content. 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 fibre concentration, decreased levels of soluble oligomers and monomers or decreased levels of reducing sugars.

Description

technical field [0001] The present invention relates to a method of preparing an animal feed product as well as an animal feed product. In particular, the present invention relates to methods relying on the hydrolysis of fermentation feedstock or non-ethanol by-products of fermentation processes, and optionally fermentation, to improve the nutritional content of the resulting animal feed products. Background technique [0002] Research efforts have been made to develop microorganisms, including Geobacillus thermophiles, to produce bioethanol from mixed pentoses and hexoses or pentoses alone. WO2007 / 110606 describes thermophilic microorganisms transformed with a gene encoding NAD-linked formate dehydrogenase to maximize ethanol production. Both WO2006 / 117536 and WO02 / 29030 describe thermophilic microorganisms carrying an inactivated lactate dehydrogenase gene. [0003] Linde (Bioresource Technology, Bioresource Technology 99 (2008) 6506-6511) studied the residual starch-fre...
