Abstract
Abstract A liquid fat with low saturated fatty acid content is hydrogenated to a slip melting point of 30*-40*C. while substantially increasing its trans acid content and providing a dilatation curve of specified steepness and is used in blends with liquid oils for the manufacture of cool-tasting margarine with little or no added lauric acid fats. The liquid and/or hydrogenated components of the blends may be interesterified and both may be derived from the same source, e.g. sunflower, safflower or rapeseed oil.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
53 words
A margarine according to claim 1, the fat blend of which consists of the partially hydrogenated fat and the fat of the lauric acid class together in an amount of at least 30 percent by weight of the fat blend, the partially hydrogenated fat comprising 20 percent to 70 percent of the blend.
Claim 2
Dependent Claim
21 words
A margarine according to claim 1, all the fat components of its fat blend being derived from a single fat species.
Claim 3
Dependent Claim
33 words
A margarine according to claim 1, wherein the partially hydrogenated fat is a partially hydrogenated rapeseed or sunflower fat, part at least of the glyceride content of which is present in random arrangement.
Claim 4
Dependent Claim
26 words
A margarine according to claim 1, which contains a randomized blend of part or all of the partially hydrogenated fat and part of the liquid fat.
Claim 5
Dependent Claim
24 words
A margarine according to claim 1, which contains a randomized blend of the fat of the lauric acid class and the partially hydrogenated fat.
Claim 6
Dependent Claim
27 words
A margarine according to claim 6, in which the proportions of the partially hydrogenated fat and lauric fat in the randomized blend are from 40:60 to 60:40.
Claim 7
Dependent Claim
