The invention relates to a process of process of producing a fermentation product, comprising: liquefying a starch-containing material to dextrins with an alpha-amylase in the presence of an asparaginase and/or an amino acid oxidase; saccharifying the dextrins to a sugar with a glucoamylase; and fermenting the sugar using a fermenting organism.

Processes of producing a fermentation product

Provided herein are methods for producing fermentable sugar obtained from a plant tissue. The methods include providing transgenic plant material comprising one or more locked carbohydrates and contacting plant material with an enzyme capable of converting the locked carbohydrate into a fermentable sugar. The methods are useful for providing sugar or sugar pre-cursors for several industrial purposes including ethanol production. The invention also encompasses plants and plant parts that produce a lock enzyme to yield a locked carbohydrate, with the consequence of accumulating the locked carbohydrate in the plant. The invention also encompasses providing a key enzyme able to convert locked carbohydrates to fermentable sugars. Key enzymes can be provided by transgenic plants or plant parts, transgenic microbes, transgenic yeast, microbes or yeast.
