Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 128 words
A process for preserving the natural body, taste and flavor of packaged freshly brewed coffee liquid without removing or degrading the colloidal material present therein which comprises preparing an aqueous coffee extract from roasted and ground coffee beans, adding to and dispersing in said coffee extract an effective amount of a propylene glycol fatty acid ester as an anti-foaming agent or a mixture of said propylene glycol fatty acid ester and a second anti-foaming agent selected from the group consisting of glycerin fatty acid esters, sorbitan fatty acid esters, and silicone resin; carbonating said coffee extract by impregnating the same with carbon dioxide under pressure and packaging said carbonated coffee extract in a sealed container; said amount being effective to reduce the foaming when said container is opened.
Claim 2
Dependent Claim 128 words
A process for preserving the natural body, taste and flavor of packaged freshly brewed coffee liquid without removing or degrading the colloidal material present therein which comprises preparing an aqueous coffee extract from roasted and ground coffee beans, adding to and dispersing in said coffee extract an effective amount of a propylene glycol fatty acid ester as an anti-foaming agent or a mixture of said propylene glycol fatty acid ester and a second anti-foaming agent selected from the group consisting of glycerin fatty acid esters, sorbitan fatty acid esters, and silicone resin; carbonating said coffee extract by impregnating the same with carbon dioxide under pressure and packaging said carbonated coffee extract in a sealed container; said amount being effective to reduce the foaming when said container is opened.
Claim 3
Dependent Claim 14 words
A process according to claim 1 wherein said second anti-foaming agent is glycerine mono-oleate.
Claim 4
Dependent Claim 31 words
A process according to claim 1 wherein said second anti-foaming agent is selected from the group consisting of sorbitan mono-laurate, sorbitan mono-stearate, sorbitan mono-oleate, sorbitan tri-stearate, sorbitan tri-oleate and sorbitan sesquioleate.
Claim 5
Dependent Claim 14 words
A process according to claim 1 wherein said second anti-foaming agent is sorbitan mono-laurate.
Claim 6
Dependent Claim 15 words
A process according to claim 1 wherein said second anti-foaming agent is propylene glycol mono-oleate.
Claim 7
Dependent Claim 15 words
A process according to claim 1 wherein said second anti-foaming agent is emulsified silicone resin.
Claim 8
Dependent Claim 31 words
A process according to claim 1 wherein the amount of said anti-foaming agent or mixture of agents per kilogram of solids in the coffee extract is 20 milligrams to 5 grams.
Claim 9
Dependent Claim 11 words
A packaged coffee beverage made by the process of claim 1.
