Process for the production of alcoholic beverages using maltseed

Abstract

The invention relates to a process for the production of alcoholic beverages such as beer or whiskey with a mixture of enzymes comprising an endo-β(1,4)-xylanase, an arabinofuranosidase, an alpha-amylase, an endo-protease and a β-(1,3; 1,4)-glucanase, and optionally, a saccharifying amylase and/or an exopeptidase. Preferable are mixtures in which the enzymes which are necessary in the brewing process are provided by transgenic seeds. Only a minor amount of malt may be necessary for flavour and colour.

1 . A process for the production of alcoholic beverages, to which a mixture of enzymes is added, which mixture comprises at least an endo-β(1,4)-xylanase, an arabinofuranosidase, an alpha-amylase, an endo-protease and a β-(1,3;1,4)-glucanase.  
     
     
         2 . A process according to  claim 1 , where the mixture also comprises a saccharifying amylase.  
     
     
         3 . A process according to  claim 1  or  2 , where the mixture also comprises an exo-peptidase.  
     
     
         4 . A process according to any of claim  1 - 3 , characterized in that that alcoholic beverage is beer.  
     
     
         5 . A process according to any one of the claims  1 - 4 , characterized in that each of said enzymes is provided by the seeds of an individual transgenic plant line.  
     
     
         6 . A process according to any of claims  1 - 4 , characterized in that that more than one enzyme is provided by the seeds of an individual transgenic plant line.  
     
     
         7 . A process according to any of claims  1 - 6 , characterized in that at least one enzyme is provided by the seeds of an individual plant line.  
     
     
         8 . A process according to any of claims  5 - 7 , characterized in that the transgenic plant line is a barley plant line.
