It has been found that the size distribution of the oil droplets or microcapsules, characterised by a value of coefficient of variation (CV) depended on the flux of the dispersed oil phase through the membrane and agitation speed of the stirrer in the dispersion cell. The smallest CV value of the microcapsules prepared by a membrane with a pore size of 15 ¦Ìm and the distance between pores of 200 ¦Ìm was 21.0 ¡À 0.5 % at a flux of the dispersed oil phase of 1.5 ¡Á 10? 5 m¡¤s? 1 and an agitation speed of 1080 rpm, and the corresponding CV value of the rupture force of the microcapsules was 18.6 ¡À 0.1 % . In comparison with the corresponding data obtained from the microcapsules made using conventional homogenization to generate emulsion droplets (CV value of 34.1 ¡À 0.3 % for diameter and 34.4 ¡À 0.2 % for rupture force), the distributions of the size and mechanical strength of the microcapsules have been significantly narrowed using the membrane emulsion, which clearly demonstrates its advantage.
