Abstract
Abstract The invention relates to fat blends of a relatively high palm oil content which fat blends are suitable for the preparation of food spreads, particularly margarine, and comprise a co-randomized and a non-randomized part, the co-randomized part comprising a palm-based fat, a lauric fat and a trans-containing fat, the non-randomized part containing such fats that the total fat blend contains well-defined proportions of saturated long-chain fatty acids, mono-trans long-chain fatty acids and saturated short-chain fatty acids. The fat blends of the invention are rapidly crystallizing even when they contain a relatively high proportion of slowly crystallizing palm oil.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
Fat blend having dilatation values at 10°C to 20°C of at least 200 and at most 1000 and at 35°C of no more than 75 consisting essentially of 10-95 percent of a co-randomized part and a balance of a non-randomized part, the co-randomized part consisting essentially of 10 to 50 percent of unhydrogenated palm oil 5 to 35 percent of lauric fats, and 10 to 50 percent of hydrogenated trans-containing fats, the non-randomized part containing fats selected from the group consisting of lauric fats, liquid oils, unhydrogenated palm oil and hydrogenated trans-containing fats such that the fat blend contains: 18-50% saturated fatty acids with 16-24 carbon atoms; 3-25% mono-trans unsaturated fatty acids with 16-24 carbon atoms; 3-30 percent saturated fatty acids with 12-14 carbon atoms; the balance being the remaining fatty acids.
Claim 2
Dependent Claim
132 words
Fat blend having dilatation values at 10°C to 20°C of at least 200 and at most 1000 and at 35°C of no more than 75 consisting essentially of 10-95 percent of a co-randomized part and a balance of a non-randomized part, the co-randomized part consisting essentially of 10 to 50 percent of unhydrogenated palm oil 5 to 35 percent of lauric fats, and 10 to 50 percent of hydrogenated trans-containing fats, the non-randomized part containing fats selected from the group consisting of lauric fats, liquid oils, unhydrogenated palm oil and hydrogenated trans-containing fats such that the fat blend contains: 18-50% saturated fatty acids with 16-24 carbon atoms; 3-25% mono-trans unsaturated fatty acids with 16-24 carbon atoms; 3-30 percent saturated fatty acids with 12-14 carbon atoms; the balance being the remaining fatty acids.
Claim 3
Dependent Claim
47 words
Fat blend according to claim 1 containing 10-45% of mono-trans unsaturated fatty acids with 16-24 carbon atoms and saturated fatty acids with 12-14 carbon atoms and no more than 60% of saturated fatty acids with 16-24 carbon atoms and mono-trans unsaturated fatty acids with 16-24 carbon atoms.
Claim 4
Dependent Claim
22 words
Fat blend according to claim 1 in which the co-randomized part is from 35-85% by weight, the remainder being the non-randomized part.
Claim 5
Dependent Claim
21 words
Fat blend according to claim 3 comprising a minor proportion of the non-randomized and a major proportion of the co-randomized part.
Claim 6
Dependent Claim
23 words
Fat blend according to claim 1 in which the percentage of palm-based fats in the co-randomized part is 15 to 45% by weight.
Claim 7
Dependent Claim
35 words
Fat blend according to claim 1 in which the non-randomized part comprises 0 to 25% of lauric fats, 0 to 50% of liquid oils, 0 to 25% palm-based fats and 0 to 35% trans-containing fats.
Claim 8
Dependent Claim
20 words
Fat blend according to claim 1 in which high trans-containing fats are used of a trans-content of 50 to 70%.
Claim 9
Dependent Claim
65 words
A margarine fat according to claim 1 which is suitable for refrigerator-type margarines, and having dilatation values at 10°C of no more than 700 and at 35°C of no more than 50, comprising 45 to 70% by weight of co-randomized constituents, the remainder being non-randomized constituents, the co-randomized part comprising 20-45% of unhydrogenated palm oil, 5-30% of lauric fats, the balance being hydrogenated trans-containing fats.
