Abstract
Non-fat and reduced fat whipped frozen dessert products wherein part or all of the milk fat, vegetable fat or oil ordinarily incorporated therein is replaced by a proteinaceous macrocolloid of , e.g., denatured whey protein particles. Illustrative embodiments include non-fat ice cream analog products having reduced calorie content, enhanced food value due to increased protein content, and possessing the physical and organoleptic character of full fat ice creams.
Claims13
In a frozen whipped dessert containing fat and/or oil, the improvement comprising the partial or total replacement of fat and/or oil therein by a macrocolloid comprising substantially non-aggregated particles of denatured protein having in a dry state a mean diameter particle size distribution ranging from about 0.1 microns to about 2.0 microns, with less than about 2 percent of the total number of particles exceeding 3.0 microns in diameter, and wherein the majority of said particles are generally spheroidal as viewed at about 800 power magnification under a standard light microscope, the particles in a hydrated state forming said macrocolloid having substantially smooth, emulsion-like organoleptic character.
In a method for preparing a frozen whipped dessert by freezing and whipping a mix of frozen dessert ingredients including fat and/or oil, the improvement comprising partially or totally replacing fat and/or oil in said mix with an effective amount of a macrocolloid comprising substantially non-aggregated particles of denatured protein having in a dry state a mean diameter particle size distribution ranging from about 0.1 microns to about 2.0 microns, with less than about 2 percent of the total number of particles exceeding 3.0 microns in diameter, and wherein the majority of said particles are generally spheroidal as viewed at about 800 power magnification under a standard light microscope, the particles in a hydrated state forming said macrocolloid having substantially smooth, emulsion-like organoleptic character.
A low or non-fat frozen whipped dessert comprising water, sweetener, flavoring, stabilizer and protein and wherein said protein provides, per cubic centimeter frozen dessert, at least 1.times.10.sup.8 denatured protein particles having diameters in the range of from 0.5 to 2.5 microns.
In a method for preparing a frozen whipped dessert wherein an aqueous mix of frozen whipped dessert ingredients is subjected to heat pasteurization prior to freezing, the improvement comprising preparing a substantially fat-free aqueous mix including from 5 to 20 percent protein of which 25 to 100 percent is heat coagulable protein and subjecting said mix to heat pasteurization and high shear conditions to form a pasteurized premix which upon freezing forms a substantially fat-free frozen whipped dessert containing, per cubic centimeter, at least 1.times.10.sup.8 denatured protein particles having diameters within the range of 0.5 to 2.5 microns.
