A low molecular weight material such as lactose in an aqueous polydispersed system such as milk is enzymatically decomposed by fermentation with enzyme preparations and/or microorganisms, the decomposition products are separated such as by ultrafiltration and the remaining solution is at least partially returned to the starting aqueous system. In a specific embodiment, lactose in milk or whey is decomposed to saccharides and lactic acid by fermenting with an enzyme preparation that splits lactose to saccharides and a microorganism that ferments lactose to lactic acid, separating the saccharides and lactic acid produced, recycling the remaining solution to the starting milk or whey, separating lactic acid from the saccharides and recycling the saccharides to the starting whey or milk. By this process, the lactose content can be partially or completely removed, lactic acid can be produced in pure form, an optimum pH can be maintained during fermentation and a sweet concentrate having 0% or reduced lactose content can be produced.
A method for enzymatically decomposing lactose in an aqueous polydispersed system selected from the group consisting of milk, skimmilk, curdled milk, whey, sour cream, buttermilk, permeated milk, and mixtures thereof, the polydispersed system having a high molecular weight component and a low molecular weight componenet containing lactose, said method comprising the steps of:
