Abstract
The present disclosure relates to an improved process of producing a fermentation product, in particular ethanol. The present disclosure relates also to the use of enzymes for improving the quality of by-products in the fermentative production process and to compositions comprising enzymes capable of degrading components in the fermented mash in the fermentation process.
Claims30
A method to improve the quality of by-products or residues derived from starch-containing material in a process for producing fermentation products comprising the steps of:
- i) adding an enzyme composition comprising an enzyme or a mixture of enzymes capable of degrading one or more fermented mash components to the fermented mash after fermentation to degrade the fermentation product, and ii) separating the desired distilling the degraded fermentation product.
A method to improve the quality of by-products or residues derived from starch-containing material in a processes for producing fermentation products comprising the steps of:
- i) adding an enzyme composition comprising an enzyme or a mixture of enzymes capable of degrading one or more fermented mash components to the fermented mash after fermentation, wherein the enzyme composition comprises a beta-1,3-glucanase and a 1,6-beta-glucanase;
- and ii) separating the desired fermentation product.
A method of producing ethanol from starch containing material, said method comprising the steps of:
- i) Converting starch containing material to fermentable sugars;
- ii) Fermentation of the fermentable sugars with a microorganism to fermented mash;
- iii) Adding an enzyme composition comprising an enzyme or a mixture of enzymes to the fermented mash after fermentation to degrade the fermentation product;
- and
- iv) Separation of the ethanol in the fermented mash degraded fermentation product by distillation.
