<p>Hard butters for confectionary are obtained by separating mid- and oelin- fractions and preferably also a stearin-fraction, from a vegetable fat containing substantial amounts of symmetrical disaturated triglycerides of C<1><6>/C<1><8> fatty acids and rearranging the gylcerides in a mixture of the olein fraction with a substantially saturated C<1><6>/C<1><8> fat, preferably the stearin fraction, in the presence of a catalyst, preferably a lipase enzyme, which is selectively active in the 1,3-positions only of glycerides, to provide increased amounts of symmetrical disaturated triglycerides which may be fractionated from the rearranged product.</p> |
