Abstract
Abstract This invention provides emulsions comprising a continuous fatty phase and a dispersed liquid aqueous phase and dispersed gelled aqueous ingredients, e.g. prepared by blending a gelling agent containing low fat spread in line with one free from gelling agents.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
An edible fat spread of the water-in-oil emulsion type comprising an aqueous phase consisting of (a) a finely dispersed non-gelled aqueous phase of a droplet size ranging from 1 to 5 microns, and (b) coarsely dispersed aqueous gelled spherical droplets of a droplet size ranging from 10 to 20 microns which contain a gelling agent and at 15°-20° C. have a gel strength ranging from 0.1 to 30 N/cm 2 as measured with an Instron apparatus employed in the linear compression test mode performed at room temperature, wherein the weight ratio of (a):(b) is 85-15: 15-85 and the weight ratio of the continuous fat phase to the combined dispersed phases is 20-80: 80-20.
Claim 2
Dependent Claim
113 words
An edible fat spread of the water-in-oil emulsion type comprising an aqueous phase consisting of (a) a finely dispersed non-gelled aqueous phase of a droplet size ranging from 1 to 5 microns, and (b) coarsely dispersed aqueous gelled spherical droplets of a droplet size ranging from 10 to 20 microns which contain a gelling agent and at 15°-20° C. have a gel strength ranging from 0.1 to 30 N/cm 2 as measured with an Instron apparatus employed in the linear compression test mode performed at room temperature, wherein the weight ratio of (a):(b) is 85-15: 15-85 and the weight ratio of the continuous fat phase to the combined dispersed phases is 20-80: 80-20.
Claim 3
Dependent Claim
21 words
Emulsion according to claim 1, wherein the weight ratio of the continuous phase to the combined dispersed phases is 35-65: 65-35.
Claim 4
Dependent Claim
80 words
A process for preparing a fat spread according to claim 1, comprising (i) producing a water-in-oil emulsion which contains a gelling agent in the aqueous phase; (ii) producing a second water-in-oil emulsion from an oil phase and an aqueous phase which does not contain any gelling agent; (iii) combining said emulsions to obtain a final emulsion containing gelled and non-gelled aqueous phases; and (iv) cooling and working the final emulsion in a surface-scraped heat exchanger to obtain a fat spread.
