A method of producing one or more of a carbohydrate ester, a protein ester, a protein subunit ester or a hydroxy acid ester, which method comprises admixing an acyl donor, an acyl acceptor and water to produce a high water environment comprising 5-98% water, wherein said acyl donor is a lipid substrate selected from one or more of the group consisting of a phospholipid, a lysophospholipid, a triacylglyceride, a diglyceride, a glycolipid or a lysoglycolipid and said acyl acceptor is selected from one or more of the group consisting of a carbohydrate, a protein, a protein subunit, or a hydroxy acid; and contacting the admixture with a lipid acyltransferase, such that said lipid acyltransferase catalyses one or both of the following reactions; alcoholysis or transesterification.

L'invention concerne un procédé permettant de produire un ou plusieurs esters de glucide, un ester de protéine, un ester de sous-unité protéique ou un ester d'hydroxy-acide. Ce procédé consiste à mélanger un donneur d'acyle, un accepteur d'acyle et de l'eau afin de produire un milieu aqueux comprenant de 5 à 98 % d'eau, ledit donneur d'acyle étant un substrat lipidique comprenant un ou plusieurs éléments sélectionnés dans le groupe constitué par un phospholipide, un lysophospholipide, un triacylglycéride, un diglycéride, un glycolipide ou un lysoglycolipide, et ledit accepteur d'acyle comprenant un ou plusieurs éléments sélectionnés dans le groupe constitué par un glucide, une protéine, une sous-unité protéique ou un hydroxy-acide, et à faire entrer en contact ce mélange avec une acyltransférase de lipide, de telle manière que cette acyltransférase catalyse une réaction d'acoolyse et/ou de transestérification.
