Abstract
Abstract 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 16 /C 18 fatty acids and rearranging the gylcerides in a mixture of the olein fraction with a substantially saturated C 16 /C 18 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
Process for the recovery of hard butter from vegetable fats wherein a vegetable fat containing substantial amounts of symmetrical disaturated triglycerides of C 16 and C 18 fatty acids is fractionally crystallised to recover the said glycerides and at least a more highly unsaturated oleine fraction, wherein the latter fraction is mixed with a substantially saturated glyceride composition and the mixture interesterified in the presence of an interesterification catalyst which is preferably a lipase enzyme selectively active in the 1-and 3-positions only of glycerides, to yield further quantities of symmetrical disaturated triglycerides and if desired separating these from the product by fractional crystallisation.
Claim 2
Dependent Claim
103 words
Process for the recovery of hard butter from vegetable fats wherein a vegetable fat containing substantial amounts of symmetrical disaturated triglycerides of C 16 and C 18 fatty acids is fractionally crystallised to recover the said glycerides and at least a more highly unsaturated oleine fraction, wherein the latter fraction is mixed with a substantially saturated glyceride composition and the mixture interesterified in the presence of an interesterification catalyst which is preferably a lipase enzyme selectively active in the 1-and 3-positions only of glycerides, to yield further quantities of symmetrical disaturated triglycerides and if desired separating these from the product by fractional crystallisation.
Claim 3
Dependent Claim
21 words
Process according to Claim 1 wherein the substantially saturated glyceride composition is recovered by fractional crystallisation from the said vegetable fat.
Claim 4
Dependent Claim
39 words
Continuous process according to Claim 1 or 2 comprising fractionation and interesterification stages between which reaction burden is circulated, into which feedstock comprising the said vegetable fat is introduced and from which a symmetrical disaturated glyceride fraction is removed.
Claim 5
Dependent Claim
18 words
Continuous process according to Claim 2 wherein an additional fraction is removed comprising 2-saturated mono- and di-unsaturated triglycerides.
Claim 6
Dependent Claim
22 words
Process according to any of the preceding claims at least part of which is carried out in solution in an organic solvent.
Claim 7
Dependent Claim
17 words
Process according to Claim 5 the fractionation part only of which is carried out in organic solvent.
Claim 8
Dependent Claim
18 words
Process according to Claim 5 or 6 wherein a solvent is used comprising acetone or a lower paraffin.
Claim 9
Dependent Claim
21 words
Process according to any of the preceding claims wherein the vegetable fat comprises aceituno, sal, shea, mango, kokum or phulwara fat.
Claim 10
Dependent Claim
11 words
Process according to claim 2 wherein the fat comprises palm oi.
Claim 11
Dependent Claim
15 words
Hard butters whenever prepared by a process as claimed in any of the preceding claims.
