Abstract: The present invention provides an oil and fat for suppressing bloom in a chocolate-like food product obtained by a simple method, or a chocolate-like food product in which said oil and fat is used. It was discovered that an oil and fat containing prescribed amounts of an SSU fat and extremely hardened high-erucic-acid rapeseed oil exhibits strong bloom resistance properties. Furthermore, it was confirmed that this effect is further enhanced by the combined use of a sorbitan fatty acid ester.

Abstract: A method for producing a composition having a disperse phase with small particle size dispersed in a continuous phase and having greater than 20% by volume of a disperse phase. The method comprising a permeation step, wherein a mixture of a continuous phase liquid and a disperse phase liquid simultaneously permeate a circumferential surface of a cylinder, which is partially or wholly composed of a porous membrane. The cylinder having outlets for the composition in the cross sections of both ends of the cylinder. The porous membrane having an average pore size of not smaller than 5 ?m at a membrane permeation rate of not lower than 50 m3/m2h. The porous membrane cylinder having a longitudinal effective membrane length, L, the internal diameter of the outlets, d, and the membrane permeation rate, F, which satisfy the relationships disclosed herein of L/d and F.

Abstract: An object of the present invention is to provide a method for producing, with high productivity, a composition having a disperse phase dispersed with a small particle size in a continuous phase. The object of the invention is achieved by a method for producing a composition having greater than 20% by volume of a disperse phase dispersed in a continuous phase, the method comprising a permeation step at which a continuous phase liquid and a disperse phase liquid are caused to simultaneously permeate a porous membrane having an average pore size of not smaller than 5 ?m at a membrane permeation rate of not lower than 50 m3/m2h.
