Embodiment Construction

[0009] The first aspect of the present invention provides a method for producing plant sterol esters and / or plant stanol esters, the method comprising: a) by mixing a phospholipid composition containing at least about 10% to about 70% plant phospholipids , Lipid acyltransferase and plant sterols and / or plant stanols and optionally water are mixed to prepare a reaction composition, wherein the reaction composition contains at least 2% w / w water; and b) separation or purification at least A plant sterol ester and / or plant stanol ester.

[0010] Another aspect of the present invention provides a method for producing plant sterol esters and / or plant stanol esters, the method comprising: a) adding at least about 10% to about 70% plant phospholipids and at least about 2% water Mixing the phospholipid composition, the lipid acyltransferase and the plant sterol and / or plant stanol; and b) separating or purifying at least one plant sterol ester and / or plant stanol ester from the mixture. ...

Abstract

The present invention relates to a method for producing phytosterol esters and / or phytostanol esters, comprising a) combining a phospholipid composition comprising at least about 10% to about 70% vegetable phospholipids and at least about 5% water, lipid acyl admixing the transferase and phytosterols and / or phytostanols; and b) separating, isolating or purifying at least one phytosterol ester and / or phytostanol ester from said mixture. The invention also relates to compositions comprising phytosterol esters and / or phytostanol esters, including food and personal care (cosmetic) compositions, produced by this method.

Description

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