Abstract
Abstract Food emulsifiers for use in food products having a foamed structure such as chemically leavened and yeast raised bakery products, whipped desserts, icecream, mousse, filling custards, toppings and icings are prepared by treating a conventional emulsifier or emulsifier mixture in the melted state with an inactive gas, preferably CO 2 , under pressure, after which the thus-treated emulsifier or emulsifier mixture is passed directly to spray crystallization and evaporation of the gas. Emulsifiers thus treated impart an increased volume to the food products prepared therewith in comparison with corresponding food products prepared with the same emulsifier without gas treatment. The treatment imparts improved shelf life to bread baked from a yeast-raised dough into which a CO 2 -treated emulsifier has been incorporated.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
96 words
A method for the production of a powdered emulsifier composition having improved leavening and aerating properties, comprising the steps of (a) heating an emulsifier composition to a temperature sufficient to melt the emulsifier, (b) gas treating the composition in a pressure vessel while the emulsifier is in the melted state with pressurized inactive gas until equilibrium is reached between the gas dissolved in the melted emulsifier and the gas in the atmosphere of the pressure vessel and (c) spray crystallizing the gas treated composition to evaporate the gas and cool the composition, thereby forming a powder.
Claim 2
Independent Claim
96 words
A method for the production of a powdered emulsifier composition having improved leavening and aerating properties, comprising the steps of (a) heating an emulsifier composition to a temperature sufficient to melt the emulsifier, (b) gas treating the composition in a pressure vessel while the emulsifier is in the melted state with pressurized inactive gas until equilibrium is reached between the gas dissolved in the melted emulsifier and the gas in the atmosphere of the pressure vessel and (c) spray crystallizing the gas treated composition to evaporate the gas and cool the composition, thereby forming a powder.
Claim 3
Dependent Claim
26 words
A method according to claim 1, wherein the gas treatment is carried out with carbon dioxide at a CO 2 pressure of 30 to 100 bar.
Claim 4
Dependent Claim
29 words
A method according to claim 2, wherein the gas treatment is carried out batchwise with substantially pure, gaseous carbon dioxide at a CO 2 pressure of about 60 bar.
Claim 5
Dependent Claim
50 words
A method according to claim 2, wherein the gas treatment is carried out continuously by pumping liquid carbon dioxide into a pressurized vessel containing the composition with emulsifier present in the molten state, the amount of liquid CO 2 being maintained at maximum 10% by volume of amount of composition.
Claim 6
Dependent Claim
25 words
A method according to claim 1, wherein the gas treatment is carried out with nitrogen at an N 2 pressure of 50 to 180 bar.
Claim 7
Independent Claim
135 words
A method for treating an emulsifier composition for use in the prepartion of leavened bakery products and whipped desserts to obtain a pulverulent form having improved leavening and aerating properties, said emulsifier composition containing at least one distilled monoglyceride of a fatty acid or salt or ester thereof comprising the steps of (a) heating the emulsifier composition to melt all fatty acid based emulsifier therein, (b) gas treating the composition in a pressure vessel while the fatty acid based emulsifier is in the molten state at an elevated temperature with an inactive gas until equilibrium is reached between the gas dissolved in the melted emulsifier and the gas in the atmosphere of the pressuure vessel and (c) spray crystallizing the gas treated composition to evaporate the gas and cool the composition, thereby forming a powder.
Claim 8
Independent Claim
135 words
A method for treating an emulsifier composition for use in the prepartion of leavened bakery products and whipped desserts to obtain a pulverulent form having improved leavening and aerating properties, said emulsifier composition containing at least one distilled monoglyceride of a fatty acid or salt or ester thereof comprising the steps of (a) heating the emulsifier composition to melt all fatty acid based emulsifier therein, (b) gas treating the composition in a pressure vessel while the fatty acid based emulsifier is in the molten state at an elevated temperature with an inactive gas until equilibrium is reached between the gas dissolved in the melted emulsifier and the gas in the atmosphere of the pressuure vessel and (c) spray crystallizing the gas treated composition to evaporate the gas and cool the composition, thereby forming a powder.
