Abstract
Process for manufacturing products with a reduced content of sterols and particularly of cholesterol, characterized in that the starting material is composed at least in part of dairy cream and is in the form of an oil-in-water emulsion, and in that it consists essentially of: contacting the starting material with a sufficient amount of cyclodextrin to form inclusion complexes with the sterols present in the fat, so as to render them extractable; inverting the oil-in-water starting emulsion into a water-in-oil emulsion; extracting the complexes formed in whole or in part.
Claims15
In a process for manufacturing dairy products reduced in sterol content, including cholesterol content, wherein an oil-in-water emulsion comprising dairy fat is used as a starting material, fat is separated from said emulsion in an intermediate step of said manufacturing process and treated with cyclodextrin to remove sterols as inclusion complexes of cyclodextrin and sterols, oil-in-water emulsion with said treated fat is reformed and used to complete said dairy product manufacture, the improvement comprising directly contacting said oil-in-water emulsion starting material with cyclodextrin during said manufacturing process, without any intermediate step of separating said fat from said oil-in-water emulsion, to form inclusion complexes with the sterols, inverting the contacted oil-in-water emulsion into a water-in-oil emulsion and separating at least part of said complexes.
