Abstract:
1. A process for hydrolyzing an oil or fat by mixing an oil-phase substrate and a water-phase substrate and feeding them as a water-in-oil emulsion to a packed layer with an immobilized enzyme immobilized on particles packed therein, wherein said oil or fat is subjected to a hydrolytic reaction under feeding conditions such that a shear stress factor (τw), is within a range of from 1 ×10 −4 to 1.4−10 −3 MPa, which is applied to a surface of said immobilized enzyme and is expressed by the following formula (1): wherein ΔP represents a maximum pressure loss [MPa] through said packed layer during said hydrolytic reaction, L represents a thickness [m] of said packed layer, dp represents a weight-basis average particle size [m] of particles of said packed, immobilized enzyme, and ε represents a void volume [−] of said packed layer.
