Abstract
1359666 Milk products SNAM PROGETTI SpA 18 Oct 1971 [17 Oct 1970] 48439/71 Heading A2B [Also in Division C3] A process for the enzymatic scission of lactose in milk or a derivative of milk comprising contacting the milk or derivative of milk with a filament in which is present the enzyme #-galactosidase, the #-galactosidase being present in the filament in a manner such that it can cause the at least partial hydrolysis of lactose and is retained substantially in the filament during hydrolysis. The enzyme may be incorporated in a filament formed from a cellulose derivative or a synthetic polymer. The cellulose derivative may be cellulose triacetate (Ex 1) whilst the polymer may be a polyamide, polyacrylonitrile, a polyacrylate, a polymethacrylate, a polyvinylchloride, a polyvinylester or a polyvinylbutyral. The enzymatic reaction may be intercalated by a washing operation with a detergent which optionally contains a bactericide. The composition produced by the process comprises milk or a derivative thereof, having a reduced concentration of lactose, and an amount of glucose and galactose corresponding to the reduction in lactose concentration, and free or substantially free of enzymatic agent. The milk may be partially skimmed, concentrated milk or whey.
