Abstract
Abstract Novel fat compositions are provided suitable for use as cocoabutter substitutes, which consist substantially of symmetrical disaturated triglycerides of C 16 and C 18 fatty acids. They may be obtained by interesterification in the presence or absence of the free fatty acids, using a 1,3-selective lipase enzyme catalyst to effect a limited degree of randomization in these positions.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
66 words
Cocoabutter replacement fat composition consisting essentially of a ternary triglyceride mixture of POP, POSt and StOSt represented on a ternary X/Y/Z composition diagram as exemplified in FIG. 1 under the curve Z 2 =4 XY, where X=StOSt, Y=POP and Z=POSt, outside a polygonal figure bounding the composition of POP, POSt and StOSt in natural fats and their blends on the diagram as exemplified in FIG. 1.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
13 words
Composition according to claim 1 lying within a segment of the said curve.
Claim 4
Dependent Claim
32 words
Composition according to claim 2 wherein the said segment is bounded on the curve by a chord extending substantially from the composition on the curve of cocoabutter to that of palm oil.
Claim 5
Dependent Claim
29 words
Composition according to claim 1 lying on the ternary diagram below a chord of the curve extending substantially from the composition of shea fat to that of palm oil.
Claim 6
Dependent Claim
27 words
Composition according to claim 1 selected from the group consisting of synthetic StOSt, POSt, POP, their mixtures with each other and with natural fats and their fractions.
Claim 7
Dependent Claim
15 words
Composition according to claim 1, at least part of which comprises a 1,3-selectively randomised fat.
Claim 8
Dependent Claim
16 words
Composition according to claim 6 comprising a fat incompletely randomised selectively in the 1- and 3-positions.
Claim 9
Dependent Claim
16 words
Composition according to claim 1 comprising up to 20% other triglycerides, balance POP, POSt and/or StOSt.
Claim 10
Dependent Claim
12 words
Composition according to claim 1 which contains palm mid-fraction or shea fat.
Claim 11
Dependent Claim
23 words
Composition according to claim 1 having a solids content at 35° C. of about 3% and at 30° C. of at least 30%.
Claim 12
Dependent Claim
22 words
Composition according to claim 1 having a solids content at 35° C. of about 4% and T max at least 28.3° C.
Claim 13
Dependent Claim
28 words
Composition according to claim 1 having a T max of at least 29° C. with a minimum rise of 3.5° C. and N 35 of at most 6%.
Claim 14
Dependent Claim
22 words
Novel fats having a composition as shown by points (4), (5), (6), (8) and (11) on FIG. 2 of the accompanying drawings.
Claim 15
Dependent Claim
22 words
Novel fats having a composition as shown by points (4), (5), (6), (8) and (11) on FIG. 2 of the accompanying drawings.
Claim 16
Dependent Claim
11 words
Composition as claimed in claim 1 in a blend with cocoabutter.
Claim 17
Dependent Claim
54 words
Method of preparing a composition as claimed in claim 1, wherein a fat comprising symmetrical disaturated triglycerides of C 16 and C 18 fatty acids is subjected to selective randomisation in the 1- and 3-positions in the presence of a lipase enzyme catalyst and a small amount of water effective to activate the catalyst.
Claim 18
Dependent Claim
13 words
Process according to claim 15, wherein the selective randomisation is discontinued before completion.
Claim 19
Dependent Claim
15 words
Process according to claim 15, wherein the randomised fat is blended with a natural fat.
Claim 20
Dependent Claim
17 words
Process according to claim 15, wherein the randomised fat is blended with synthetic POP, POSt, and/or StOSt.
Claim 21
Dependent Claim
39 words
Continuous process according to claim 15, wherein a stream of the fat in solution is directed over a fixed bed of selective enzyme catalyst and the randomised fat is recovered from the effluent by removal of the said solvent.
Claim 22
Dependent Claim
25 words
Process according to claim 19, wherein the extent of selective 1,3-randomisation of the fat is limited by adjusting the rate of flow of the stream.
