An Ultrafiltration (UF) based reactor system for continuous hydrolysis of proteins was developed to overcome limitations of the traditional batch process. A continuous stirred tank reactor was coupled to a hollow fiber module in a semiclosed loop configuration. Capacity of the reactor, defined as quantity of hydrolysate produced/time/weight of enzyme, was a sensitive function of enzyme concentration between 55 and 94% substrate conversion levels for the Pronase‐Promine D system. Increasing flow rate also improved capacity, but substrate concentration and reactor volume had small effects on capacity within the levels of expected use. Productivity (defined as weight of hydrolysate/weight of enzyme) was at least 10‐20 times greater for the continuous UF reactor than a batch reactor operating under otherwise identical conditions.
