摘要:
A method for producing an emulsion by dispersing a liquid to form a disperded phase into a liquid to form a continuous phase through a microporous membrane, in which :
(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 ; (b) an O1/W/O2 type emulsion is produced by dispersing an O/W type emulsion at low pressure into the fatty phase(O2) through the same microporous membrane as (a) above; (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 :
(d) a W/O type emulsion for low-fat spread is prepared by dispersing an aqueous phase into a fatty phase trough a microporous membrane : (e) an O1/W/O2 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.
