Abstract
Abstract The invention relates to fat compositions of a relatively high liquid oil content, which compositions are suitable for preparing margarines with a high percentage of polyunsaturated fatty acids. The fat compositions of the invention contain, apart from said liquid oil, 5-30% of a hard fat of a well-defined fatty acid and triglyceride composition, i.e. 25-60% H3 and H2T triglyceride, 30-70% H fatty acids, 10-45% T fatty acids, 0-25% M fatty acids, 15-45% M + T fatty acids, the balance being L fatty acids, (H, T, M and L stand for saturated fatty acids with 16-24 carbon atoms, mono-trans unsaturated fatty acids with 16-24 carbon atoms, saturated fatty acids with 12-14 carbon atoms and the remainder, being 100-(H + T + M)% respectively).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
Margarine fat consisting essentially of (a) a liquid vegetable oil having a polyunsaturated fatty acid content of at least 40% and (b) 5-30% of a hard fat containing: I. 25-60% of triglycerides containing three saturated fatty acids with 16-24 carbon atoms and triglycerides containing two saturated fatty acids with 16-24 carbon atoms and one mono-trans-unsaturated fatty acid with 16-24 carbon atoms, Ii. 35-70% of saturated fatty acids with 16-24 carbon atoms, Iii. 20-35% of mono-trans-unsaturated fatty acids with 16-24 carbon atoms, Iv. 0.25% of saturated fatty acids with 12-14 carbon atoms, V. 15-45% of saturated fatty acids with 2-14 carbon atoms and mono-trans-unsaturated fatty acids with 16-24 carbon atoms, Vi. the balance being the remaining fatty acids, to provide from 0.2-5% triglycerides containing three saturated fatty acids with 16-20 carbon atoms in the margarine fat.
Claim 2
Dependent Claim
135 words
Margarine fat consisting essentially of (a) a liquid vegetable oil having a polyunsaturated fatty acid content of at least 40% and (b) 5-30% of a hard fat containing: I. 25-60% of triglycerides containing three saturated fatty acids with 16-24 carbon atoms and triglycerides containing two saturated fatty acids with 16-24 carbon atoms and one mono-trans-unsaturated fatty acid with 16-24 carbon atoms, Ii. 35-70% of saturated fatty acids with 16-24 carbon atoms, Iii. 20-35% of mono-trans-unsaturated fatty acids with 16-24 carbon atoms, Iv. 0.25% of saturated fatty acids with 12-14 carbon atoms, V. 15-45% of saturated fatty acids with 2-14 carbon atoms and mono-trans-unsaturated fatty acids with 16-24 carbon atoms, Vi. the balance being the remaining fatty acids, to provide from 0.2-5% triglycerides containing three saturated fatty acids with 16-20 carbon atoms in the margarine fat.
Claim 3
Dependent Claim
51 words
Margarine fat composition according to claim 1 in which the the content of triglycerides containing two saturated fatty acids with 16-24 carbon atoms and one mono-trans-unsaturated fatty acid with 16-24 carbon atoms of the hard fat component is higher than the triglycerides containing three saturated fatty acids with 16-24 carbon atoms.
Claim 4
Dependent Claim
12 words
Margarine fat composition according to claim 1 containing 9-15% of hard fat.
Claim 5
Dependent Claim
38 words
Margarine fat composition according to claim 1 containing a hard fat obtained by co-randomizing one mixture of two or three fats, at least one of which being a mono-trans-unsaturated fatty acid with 16-24 carbon atoms containing hydrogenated fat.
Claim 6
Dependent Claim
28 words
Margarine fat composition according to claim 4 in which a mixture of two or three hydrogenated fats of a slip melting point ranging from 32°-70° C. is used.
