Abstract
Abstract A method of manufacturing an expanded temperature-resistant, chocolate product, comprises mixing intimately water, at least one edible fat, sugar and an emulsifier to produce an emulsion of said fat with an aqueous sugar solution. The solution is then evaporated to about 10% moisture content while maintaining the fat in emulsion. Finally, the mixture is dried, preferably under reduced pressure, with gasification to produce an expanded product containing 15-35% fat, at least 40% sugar and not more than 5%, preferably not more than 2%, water. The product contains individual fat particles which are separated from one another in a sugar glass so that fat seepage from the product at elevated ambient temperatures is obviated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
176 words
A method of manufacturing a shaped heat-resistant chocolate product comprising the steps of (i) thoroughly mixing at least the following ingredients: water, 15 to 35% by weight of at least one edible fat selected from (a) cocoa butter and (b) cocoa butter and at least one other fat, and not less than 40% by weight of sugar, said percentages being based on the total weight of the chocolate product, so as to produce an aqueous sugar solution in which said at least one edible fat is emulsified with the solution, (ii) maintaining said at least one edible fat emulsified with the aqueous sugar solution, evaporating sufficient water from the solution to prevent separation of said at least one edible fat from the said aqueous sugar solution, (iii) shaping the resultant evaporated mixture, and (iv) drying the shaped mixture so as to produce a shaped heat-resistant chocolate product having a moisture content of not more than 5% by weight and such that individual particles of said at least one edible fat are encapsulated in a sugar glass.
Claim 2
Independent Claim
176 words
A method of manufacturing a shaped heat-resistant chocolate product comprising the steps of (i) thoroughly mixing at least the following ingredients: water, 15 to 35% by weight of at least one edible fat selected from (a) cocoa butter and (b) cocoa butter and at least one other fat, and not less than 40% by weight of sugar, said percentages being based on the total weight of the chocolate product, so as to produce an aqueous sugar solution in which said at least one edible fat is emulsified with the solution, (ii) maintaining said at least one edible fat emulsified with the aqueous sugar solution, evaporating sufficient water from the solution to prevent separation of said at least one edible fat from the said aqueous sugar solution, (iii) shaping the resultant evaporated mixture, and (iv) drying the shaped mixture so as to produce a shaped heat-resistant chocolate product having a moisture content of not more than 5% by weight and such that individual particles of said at least one edible fat are encapsulated in a sugar glass.
Claim 3
Dependent Claim
15 words
A method as claimed in claim 1, wherein an emulsifier is included in the solution.
Claim 4
Dependent Claim
23 words
A method as claimed in claim 1, wherein the drying step is effected to give a moisture content of not more than 2%.
Claim 5
Dependent Claim
16 words
A method as claimed in claim 1, wherein the edible composition is produced in expanded form.
Claim 6
Dependent Claim
21 words
A method as claimed in claim 4, wherein the edible composition is produced in expanded form by gasifying said shaped mixture.
Claim 7
Dependent Claim
29 words
A method as claimed in claim 4 wherein the edible composition is produced in expanded form by flash heating said shaped mixture in order to effect the drying step.
Claim 8
Dependent Claim
16 words
A method as claimed in claim 6, wherein said flash heating is effected under reduced pressure.
Claim 9
Dependent Claim
32 words
A method as claimed in claim 1, wherein said drying step is effected by injecting the shaped mixture through at least one injection nozzle onto a supporting surface in a vacuum chamber.
Claim 10
Dependent Claim
39 words
A method as claimed in claim 8, wherein the shaped mixture is injected onto a moving conveyor which conveys the injected material from a heated zone in the vacuum chamber to a cooler, solidification zone in the vacuum chamber.
Claim 11
Dependent Claim
51 words
A method as claimed in claim 9, wherein the shaped mixture is injected continuously onto the moving conveyor so as to produce at least one continuous length of the emulsified mixture to be dried each continuous length being cut to the desired length in the vacuum chamber before being discharged therefrom.
Claim 12
Dependent Claim
18 words
A method as claimed in claim 1, wherein the drying step is effected by heating by micro-wave energy.
