Abstract
Abstract The invention is concerned with margarine fats suitable for the preparation of margarines and low-fat spreads. The fat blend has a difference in dilatation values at 15° and 25° C. of at least 100 and has a dilatation value at 35° C. of less than 100 and is substantially free from fats other than those containing at least 80% by weight of fatty acid residues with 18 carbon atoms. Part of the fats are hardened and part of the non-hardened fats are interesterified with hardened fats containing no more than 55% trans-acids. The non-interesterified part of the margarine fat contains non-hardened fats and fats hardened to a trans-content of 50-70%.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
Margarine fat having a difference in dilation value at 15° and 25° C. of at least 100 and a dilation value at 35° C. of no more than 100, comprising at least 95 percent of fats containing at least 80 percent by weight of fatty acid residues with 18 carbon atoms, part of these fats being hardened and part of the non-hardened fats being interesterified with hardened fats which contain no more than 55 percent of trans-acids, such that the margarine fat contains 20-60 percent by weight of interesterified fats, and 80-40 percent by weight of non-interesterified fats the non-interesterified fats containing both non-hardened fats and fats hardened to a trans-content of 50-70 percent, the weight ratio between hardened and non-hardened fats in the non-interesterified part being from 1:1 to 1:5 and the weight ratio between the hardened and non-hardened fats in the interesterified part being from 4:1 to 1:3.
Claim 2
Dependent Claim
150 words
Margarine fat having a difference in dilation value at 15° and 25° C. of at least 100 and a dilation value at 35° C. of no more than 100, comprising at least 95 percent of fats containing at least 80 percent by weight of fatty acid residues with 18 carbon atoms, part of these fats being hardened and part of the non-hardened fats being interesterified with hardened fats which contain no more than 55 percent of trans-acids, such that the margarine fat contains 20-60 percent by weight of interesterified fats, and 80-40 percent by weight of non-interesterified fats the non-interesterified fats containing both non-hardened fats and fats hardened to a trans-content of 50-70 percent, the weight ratio between hardened and non-hardened fats in the non-interesterified part being from 1:1 to 1:5 and the weight ratio between the hardened and non-hardened fats in the interesterified part being from 4:1 to 1:3.
Claim 3
Dependent Claim
20 words
Margarine fat according to claim 1, containing 25-50% by weight of interesterified fats and 75-50% by weight of non-interesterified fats.
Claim 4
Dependent Claim
39 words
Margarine fat according to claim 1, in which the fats containing at least 80% by weight of fatty acid residues with 18 carbon atoms are those which in non-hydrogenated form contain at least 40% by weight of linoleic acid.
