The present invention relates to a method of reducing and/or removing diglyceride from an edible oil, comprising a) admixing an edible oil with an acyl acceptor substrate and a fatty-acid CoA independent diglyceride: glycer ol acyltransferase, wherein the fatty-acid CoA independent diglyceride: glycero l acyltransferase is characterized as an enzyme which in an edible oil is capable of transferring an acyl group from a diglyceride to glycerol. Preferably, the diglyceride: glycerol acyltransferase comprises the amino ac id sequence motif GDSX, wherein X is one or more of the following amino acid residues L, A, V, I, F, Y, H, Q, T, N, M or S. Furthermore the present invention relates to the use of a fatty-acid CoA independent diglyceride: glycerol acyltransferase characterized as an enzyme which in an edible oil i s capable of transferring an acyl group from a diglyceride to glycerol, in the manufacture of an edible oil, for reducing and/or removing (preferably selectively reducing and/or removing) diglyceride from said edible oil, and to the use of said enzyme in the manufacture of a foodstuff comprising an edibl e oil for improving the crystallization properties of said foodstuff. |
