ABSTRACT:
A superattenuated low caloric beer is produced by passing fermenting beer through an immobilized glucoamylase reactor having active glucoamylase immobilized on a ceramic monolith. The ceramic monolith has open ended passages ranging from 50 to 3,000 microns in diameter through which the beer passes, and glucoamylase is covalently bonded to internal surfaces of the passages. The glucoamylase is preferably covalently bonded by reacting an aldehydic derivative of glucoamylase with an aminofunctional group on the internal surfaces of the passages to form an aldimine which is reduced to a secondary amine. The reactor can sustain high flow rates of beer containing yeast and other particulate matter without plugging or fouling, and it is operationally stable under fermentation conditions over a long period of time.
