METHODS FOR PRODUCING EMULSIONS, LOW-FAT SPREAD AND OIL-IN-WATER-IN-OIL TYPE SPREAD

摘要

ABSTRACTA method for producing an emulsion by dispersing a liquidto form a dispersed phase into a liquid to form a continuousphase through a microporous membrane, in which:(a) a W/0 type emulsion is produced by dispersing an aqueousphase at low pressure into a fatty phase through a hydrophilicmicroporous membrane previously treated with the fatty phase;(b) an 01/W/02 type emulsion is produced by dispersing an 0/Wtype emulsion at low pressure into the fatty phase (02) throughthe same microporous membrane as (a) above;(c) an 0/W type emulsion is produced by dispersing a fattyphase containing a hydrophobic emulsifying agent into an aqueousphase through a hydrophilic microporous membrane.Furthermore, methods for producing a low-fat spread and anoil-in-water-in-oil type spread by rapidly cooling a emulsion toplasticize and kneading, in which:(d) a W/0 type emulsion for low-fat spread is prepared bydispersing an aqueous phase into a fatty phase trough amicroporous membrane:(e) an 01/W/02 type emulsion for an oil-in-water-in-oil typespread is prepared by dispersing an 01/W type emulsion into afatty phase (02) through the same membrane as (d) above.
