CONFECTIONERY PRODUCT
The present invention resides in an edible aerated water-in-oil emulsion comprising a fat phase; an emulsifier; and an aqueous phase, methods of making such emulsions and confectionery compositions comprising the same. In certain embodiments the emulsion comprises entrapped gas (for example in the fat phase); the fat phase comprises more than one fat (for example one of the fats being cocoa butter); the emulsifier having an HLB <8; and/or the emulsion additionally comprising a powdered component.

3 . The aerated emulsion as claimed in claim 2 , wherein the emulsion comprises at least 30% v/v entrapped gas.
4 . The aerated emulsion as claimed in claim 1 , wherein the aqueous phase comprises entrapped gas.
5 . The aerated emulsion as claimed in claim 1 , wherein the fat phase comprises entrapped gas.
6 . The aerated emulsion as claimed in claim 1 , wherein the fat phase comprises a first fat having a first melting point, and a second fat having a second melting point lower than the first melting point.
7 . The aerated emulsion as claimed in claim 6 , wherein the first fat can exist in more than one crystal form and is present in the emulsion in substantially a single crystal form.
8 . The aerated emulsion as claimed in claim 7 , wherein the first fat is a tempering fat.
9 . The aerated emulsion as claimed in claim 8 , wherein the first fat is cocoa butter.
10 . The aerated emulsion as claimed in claim 6 , wherein the second fat is a non-tempering fat.
11 . The aerated emulsion as claimed in claim 10 , wherein the second fat is palm oil.
12 . The aerated emulsion as claimed in claim 6 , wherein the ratio of the first fat to the second fat is between 3:1 and 1:3.
13 . The aerated emulsion as claimed in claim 1 , wherein the emulsifier has an HLB value of less than 8.
14 . The aerated emulsion as claimed in claim 1 , wherein the emulsifier comprises polyglycerol polyricinoleate.
15 . The aerated emulsion as claimed in claim 1 , wherein the fat phase forms less than 30% of the emulsion.
16 . The aerated emulsion as claimed in claim 1 , wherein the aqueous phase comprises a gelling agent.
17 . The aerated emulsion as claimed in claim 1 , further comprising a powdered component.
18 . A confectionery composition comprising the aerated emulsion as claimed in claim 1 .
19 . The confectionery composition as claimed in claim 18 , wherein the aerated emulsion forms at least part of a filling, and the confectionery composition further comprises a shell or coating at least partially enclosing the filling.
20 . A method of making an emulsion as claimed in claim 1 , comprising providing a first component for forming the fat phase of an emulsion; providing a second component for forming the aqueous phase of an emulsion; mixing the first component and second component to form a water-in-oil emulsion; and aerating the water-in-oil emulsion.
21 . The method as claimed in claim 20 , wherein aerating the water-in-oil emulsion comprises whipping the water-in-oil emulsion.
22 . The method as claimed in claim 20 , wherein aerating the water-in-oil emulsion comprises introducing gas into the emulsion under pressure, and reducing the pressure to cause gas bubbles trapped in the emulsion to expand.
23 . The method as claimed in claim 20 , wherein the first component comprises a first fat having a first melting point and a second fat having a second melting point; providing the first component comprises providing the first component at a temperature greater than the first melting point; and the method further comprises cooling the emulsion to a temperature less than the first melting point but greater than the second melting point, before completion of aeration of the emulsion.
24 . The method as claimed in claim 20 , further comprising the addition of a powdered component to the emulsion.
25 . The method as claimed in claim 24 , wherein the powdered component is added to the emulsion before aeration of the emulsion.
26 . The method as claimed in claim 24 , wherein the powdered component is added to the emulsion after aeration of the emulsion.
27 . The method as claimed in claim 20 , wherein the method further comprises aerating the second component before mixing the first and second components to form the emulsion.
28 . A method for making an emulsion as claimed in claim 1 , comprising providing a first component for forming the fat phase of an emulsion; providing a second component for forming the aqueous phase of an emulsion; aerating the second component; and mixing the first component and aerated second component to form a water-in-oil emulsion.
29 . The method as claimed in claim 28 , wherein the first component comprises a first fat having a first melting point and a second fat having a second melting point; providing the first component comprises providing the first component at a temperature greater than the first melting point; and the method further comprises cooling the mixture of first and second components to a temperature less than the first melting point but greater than the second melting point, before completion of mixing the first and second components to form the emulsion.
