Abstract
Abstract A protein-free, lipoidal coffee whitener, the functional ingredients of which consist essentially of a pasteurized, homogenized water-rich lipoidal emulsion of about 6-15% edible fat and about 0.6-1.5% mixed lipoidal emulsifier, said fat having a Wiley Melting Point below about 120° F., said emulsifier constituting about 0.3-1.09%, low HLB, mono- and diglyceride or propylene glycol partial ester of fat-forming acids and about 0.1-0.45% hard, ionizable, lipoidal emulsifier component.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
129 words
A fluid, protein-free, lipoidal coffee whitener in the form of a pasteurized, homogenized, water-rich lipoidal emulsion, suitable for addition to an acidic environment, the functional ingredients of which consist essentially of about 83.5-93.4% water; about 6-15% edible fat; about 0.6-1.5% mixed lipoidal emulsifier; said fat having a Wiley Melting Point below about 120° F.; said emulsifier constituting about 0.3-1.05% mono- and diglyceride or propylene glycol partial ester of fat-foaming acids having an HLB not substantially greater than about 5 and about 0.1-0.45% of a solid, ionizable, lipoidal, emulsifier component; said ingredients providing a viscosity similar to that of a conventional casein-containing fluid coffee whitener and less than about 20 centipoises at 40° F. as measured on a Brookfield Viscometer, Model LVF, using a No. 1 spindle at 60 RPM.
Claim 2
Dependent Claim
129 words
A fluid, protein-free, lipoidal coffee whitener in the form of a pasteurized, homogenized, water-rich lipoidal emulsion, suitable for addition to an acidic environment, the functional ingredients of which consist essentially of about 83.5-93.4% water; about 6-15% edible fat; about 0.6-1.5% mixed lipoidal emulsifier; said fat having a Wiley Melting Point below about 120° F.; said emulsifier constituting about 0.3-1.05% mono- and diglyceride or propylene glycol partial ester of fat-foaming acids having an HLB not substantially greater than about 5 and about 0.1-0.45% of a solid, ionizable, lipoidal, emulsifier component; said ingredients providing a viscosity similar to that of a conventional casein-containing fluid coffee whitener and less than about 20 centipoises at 40° F. as measured on a Brookfield Viscometer, Model LVF, using a No. 1 spindle at 60 RPM.
Claim 3
Dependent Claim
16 words
The coffee whitener of claim 1 wherein said ionizable lipoidal emulsifier component is sodium stearoyl lactylate.
Claim 4
Dependent Claim
71 words
The coffee whitener of claim 2 wherein said coffee whitener is prepared by blending the lipid ingredients with water at an elevated temperature sufficient to render the lipid ingredients molten and heating for a time and temperature sufficient to pasteurize or sterilize the same, then homogenizing the blend in a two-stage homogenizer at 2500 psig and 500 psig, respectively, followed by rapid cooling to about 40° and packaging of the same.
Claim 5
Dependent Claim
27 words
The coffee whitener of claim 1 wherein said mixed lipoidal emulsifier comprises a mono- and diglyceride and sodium stearoyl lactylate in the ratio of about 7;3, respectively.
Claim 6
Dependent Claim
18 words
The coffee whitener of claim 4 wherein the total lipid content of said lipoidal emulsifier is about 10%.
Claim 7
Dependent Claim
20 words
The coffee whitener of claim 1 containing sugar added in low amounts to a sweetness level existing in ordinary cream.
Claim 8
Dependent Claim
33 words
The coffee whitener of claim 1 having a viscosity less than about 20 centipoises at 40° F. as measured on a Brookfield Viscometer, Model LVF, using a No. 1 spindle at 60 rpm.
Claim 9
Dependent Claim
19 words
The coffee whitener of claim 1 wherein the fat has an AOM stability of at least about 100 hours.
Claim 10
Dependent Claim
18 words
The coffee whitener of claim 1 homogenized to an average particle size of less than about 1 micron.
Claim 11
Independent Claim
131 words
A method for the preparation of fluid, protein-free, lipoidal coffee whiteners, suitable for addition to an acidic environment, comprising the steps of preparing a water-rich, lipoidal emulsion by mixing functional ingredients consisting essentially of about 83.5-93.4% water; about 6-15% edible fat; about 0.6-1.5% mixed lipoidal emulsifier; said fat having a Wiley Melting Point below about 120° F.; said emulsifier constituting about 0.3-1.05% mono- and diglyceride or propylene glycol partial ester of fat-forming acids having an HLB not substantially greater than about 5 and about 0.1-0.45% of a solid, ionizable, lipoidal, emulsifier component; subjecting said emulsion to pasteurization, homogenization, cooling and packaging; said coffee whitener having a viscosity less than about 20 centipoises at 40° F. as measured on a Brookfield Viscometer, Model LVF, using a No. 1 spindle at 60 RPM.
Claim 12
Independent Claim
131 words
A method for the preparation of fluid, protein-free, lipoidal coffee whiteners, suitable for addition to an acidic environment, comprising the steps of preparing a water-rich, lipoidal emulsion by mixing functional ingredients consisting essentially of about 83.5-93.4% water; about 6-15% edible fat; about 0.6-1.5% mixed lipoidal emulsifier; said fat having a Wiley Melting Point below about 120° F.; said emulsifier constituting about 0.3-1.05% mono- and diglyceride or propylene glycol partial ester of fat-forming acids having an HLB not substantially greater than about 5 and about 0.1-0.45% of a solid, ionizable, lipoidal, emulsifier component; subjecting said emulsion to pasteurization, homogenization, cooling and packaging; said coffee whitener having a viscosity less than about 20 centipoises at 40° F. as measured on a Brookfield Viscometer, Model LVF, using a No. 1 spindle at 60 RPM.
