Production of Stilbenoids

Abstract

A method for the production of a stilbenoid, such as resveratrol or pinosylvin, by fermenting plant material such a grape must using a yeast having a metabolic pathway producing said stilbenoid, separating a solids waste material from said fermentation and extracting said stilbenoid.

1 . A method for the production of a mixture comprising stilbenoids, comprising extracting resveratrol or pinosylvin from a solids waste material separated from a fermentation of plant material conducted using a genetically modified yeast strain having a metabolic pathway producing the mixture comprising stilbenoids. 
     
     
         2 . The method of  claim 1 , further comprising the preliminary steps of conducting said fermentation of plant material using the genetically modified yeast strain having a metabolic pathway producing the mixture comprising stilbenoids and separating a solids waste material from said fermentation. 
     
     
         3 . The method of  claim 1 , wherein the fermentation is a fermentation of fruit must together with or separated from pommace. 
     
     
         4 . The method of  claim 1 , wherein the fermentation is a fermentation of pommace separated from fruit must. 
     
     
         5 . The method of  claim 2 , wherein the fruit is grape, apple or pear. 
     
     
         6 . The method of  claim 1 , wherein the fermentation is a beer making fermentation. 
     
     
         7 . The method of  claim 1 , wherein the genetically modified yeast strain is genetically modified  Saccharomyces  yeast. 
     
     
         8 . The method of  claim 1 , further comprising the step of recovering resveratrol or pinosylvin.
