That's the basic function of Beano - it shreds complex sugars that are not digested by humans, but are disgested by intestinal flora.
Search for "beano" here, or "beano fermentation" on google in general.
From what I gather it's a last ditch effort for stuck fermentation, because it tends to result in excessively dry beers.
When you eat two or three Beano tablets, the vast majority of the galactosidase is burnt off by stomach acids that don't exist in wort.
Haven't tried it myself.
