Abstract
A method for producing an emulsion by dispersing a liquid to form a dispersed phase into a liquid to form a continuous phase through a microporous membrane, in which: PA0 (a) a W/O type emulsion is produced by dispersing an aqueous phase at low pressure into a fatty phase through a hydrophilic microporous membrane previously treated with the fatty phase; PA0 (b) an 01/W/02 type emulsion is produced by dispersing an O/W type emulsion at low pressure into the fatty phase (02) through the same microporous membrane as (a) above; PA0 (c) an O/W type emulsion is produced by dispersing a fatty phase containing a hydrophobic emulsifying agent into an aqueous phase through a hydrophilic microporous membrane. Furthermore, methods for producing a low-fat spread and an oil-in-water-in-oil type spread by rapidly cooling a emulsion to plasticize and kneading, in which: PA0 (d) a W/O type emulsion for low-fat spread is prepared by dispersing an aqueous phase into a fatty phase through a microporous membrane: PA0 (e) an 01/W/02 type emulsion for an oil-in-water-in-oil type spread is prepared by dispersing an 01/W type emulsion into a fatty phase (02) through the same membrane as (d) above.
