A method for reducing the free fatty acid content of frying facts and oils that comprises heating the flying fat or oil to a temperature of less than about 120.degree. C. and stirring into the heated fat or oil less than about 10% by weight of cyclodextrin and less than about 10% by weight of a powdered absorbent to form a slurry. Allowing the slurry mixture to react for less than about one and one half hours and then separating the cyclodextrin, absorbent material and free atty acid from the frying fat or oil, thereby reducing the free fatty acid content of the remaining frying fat or oil.

Free fatty acid removal from used frying fat

Butter oil is heated under high vacuum and sparged for up to about 6 hours to remove cholesterol. Walls surrounding a vapor space above the sparged mass preferably are heated to remove cholesterol with reduced loss of desirable low molecular weight components. Alternatively, the temperature of the butter oil is lowered, and the butter oil is sparged with steam for an additional period of up to about 3 hours to partially hydrolyze triglycerides to mono- and di-glycerides and free fatty acids. The low cholesterol butter oil then is cooled before being exposed to air, thus avoiding oxidation which produces off-flavors. The resulting low-cholesterol butter fat and products made therefrom have composition and organoleptic characteristics substantially similar to those of natural butter oil and butter.

Production of low cholesterol butter oil by vapor sparging

Edible oil containing monoglyceride is emulsified with a mixture of cholesterol-containing egg in aqueous solution. Then, the mixture is heated and typically is stirred gently to ensure intimate admixture of the oil phase in the aqueous phase. The monoglyceride serves to facilitate oil/lipoprotein interaction in the presence of aqueous phase. The fat in the egg is partitioned into the monoglyceride-containing oil phase. Agitation is continued for a time sufficient to exchange or extract cholesterol and fat from the aqueous phase to the oil phase. The cholesterol- and fat-reduced aqueous phase is the desired low-cholesterol egg product, and is separated from the cholesterol-enriched oil phase.

Method for removing cholesterol from eggs

A process for the production of low-cholesterol milk fat wherein the milk fat is separated into at least one aqueous fraction and a cream fraction. The cream fraction is washed and reseparated a plurality of times to provide a washed cream fraction containing substantially undisturbed milk fat globules and substantially intact milk fat globule membranes. Cholesterol is preferentially extracted from the milk fat globule membranes with an organic polar solvent and without substantial loss of the solid milk fat. Solvent-free, low-cholesterol product is recovered from the reseparated, washed cream fraction. This low-cholesterol milk fat product has composition and organoleptic characteristics substantially similar to those of natural milk fat. The invention also relates to a low-cholesterol milk fat product having composition and organoleptic characteristics substantially similar to those of natural milk fat and produced by the method of this invention.

Production of low-cholesterol milk fat by solvent extraction

The production of bland, functional, defatted soy flour in which hulled soybeans are heat treated by wet and dry heat to inactivate the enzymes, are dehulled and cracked, are thereafter defatted and washed under an inert atmosphere and then dried and milled.
