Abstract

The present invention relates to a method of producing a phytosterol ester and / or a phytostanol ester comprising: a) admixing a phospholipid composition comprising at least between about 10% to about 70% plant phospholipid and at least about 5% water; a lipid acyltransferase; and a phytosterol and / or a phytostanol; and b) separating or isolating or purifying at least one phytosterol ester and / or phytostanol ester from said admixture. The present invention also relates to compositions comprising the phytosterol ester and / or phytostanol ester produced by this method, including foodstuffs and personal care product (cosmetic) compositions.

Description

technical field [0001] The present invention relates to a method for producing phytosterol esters and / or phytostanol esters using lipid acyltransferase. The present invention further relates to the use of lipid acyltransferases for the production of phytosterol esters and / or phytostanol esters. Background technique [0002] It is known that phytosterol esters are introduced into foods such as mayonnaise and margarine mainly due to their cholesterol-lowering effect. Foods rich in phytosterol esters or phytostanol esters are often referred to as "functional foods" (ie rich in margarine). Phytostanol esters and phytosterol esters have also been used by the personal care (cosmetic) industry. The use of sterol and / or stanol esters in food and other applications is more preferred than free sterols or stanols because sterol and / or stanol esters are more stable. [0003] Traditionally, sterol esters and / or stanol esters have been produced by chemical esterification of the corresp...
