The present application provides a method of reducing and/or removing diglyceride from an edible oil, comprising admixing an edible oil with an acyl acceptor substrate and a diglyceride:glycerol acyltransferase, wherein the diglyceride:glycerol acyltransferase is characterized as an enzyme which in an edible oil is capable of transferring an acyl group from a diglyceride to glycerol. The diglyceride:glycerol acyltransferase can comprise the amino acid sequence motif GDSX. The present invention also relates to the use of a diglyceride:glycerol acyltransferase in the manufacture of an edible oil, for reducing and/or removing diglyceride from said edible oil and to the use of said enzyme in the manufacture of a foodstuff comprising an edible oil for improving the crystallization properties of said foodstuff.
