Abstract
Abstract There is disclosed a process for producing a water-in-oil emulsion spread from a starting oil-in-water dairy cream which is substantially free from added emulsifiers. By shearing and cooling the dairy cream in the absence of a cream/air interface using an apparatus means internally coated with a hydrophobic material, an inversion occurs to produce the final water-in-oil emulsion spread.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
A process for producing a water-in-oil emulsion spread having a fat content of at most 60%, comprising (i) providing an oil-in-water emulsion from a fatty phase and an aqueous phase at a temperature at which the fatty phase is melted, said emulsion being a dairy cream which is substantially free from added emulsifiers; (ii) shearing and cooling said emulsion in the absence of a cream/air interface, using apparatus means internally coated with a hydrophobic material, to cause phase inversion and obtain a water-in-oil emulsion-spread having the same level of fat as the starting oil-in-water emulsion.
Claim 2
Dependent Claim
95 words
A process for producing a water-in-oil emulsion spread having a fat content of at most 60%, comprising (i) providing an oil-in-water emulsion from a fatty phase and an aqueous phase at a temperature at which the fatty phase is melted, said emulsion being a dairy cream which is substantially free from added emulsifiers; (ii) shearing and cooling said emulsion in the absence of a cream/air interface, using apparatus means internally coated with a hydrophobic material, to cause phase inversion and obtain a water-in-oil emulsion-spread having the same level of fat as the starting oil-in-water emulsion.
Claim 3
Dependent Claim
14 words
A process according to claim 1, wherein the apparatus is internally coated with polytetrafluorethylene.
Claim 4
Dependent Claim
40 words
A process according to claim 1, wherein the apparatus, prior to step (ii), is internally coated by flushing with a plastic fat containing a component selected from the group consisting of a mono-glyceride, a di-glyceride, a phospholipid or mixtures thereof.
Claim 5
Dependent Claim
13 words
A process according to claim 3, wherein the plastic fat comprises butter oil.
Claim 6
Dependent Claim
30 words
A process according to claim 1 wherein a water-in-oil emulsion spread is produced in which the diameter of the dispersed drops of aqueous phase ranges from 2 to 20 microns.
Claim 7
Dependent Claim
19 words
A process according to claim 1, wherein a water-in-oil emulsion with a fat content of 15-35 wt.% is produced.
Claim 8
Dependent Claim
22 words
A process according to claim 6, wherein the diameter of the dispersed drops of aqueous phase ranges from 8 to 20 microns.
