Abstract

A fatty material enzyme interesterification process comprising the steps of: a) providing a fatty material that has optionally undergone at least one prior purification treatment; b) introducing soap into said fatty material to form a soap-containing fatty material mixture, c) homogenising said soap-containing fatty material mixture by mixing, d) contacting said soap-containing fatty material mixture with lipase to produce a soap-containing interesterified fatty material, e) removing soaps from said soap-containing interesterified fatty material to yield interesterified fatty material, wherein said soap is either formed in-situ by addition of aqueous alkali to said fatty material or said soap is introduced directly into said fatty material.
