Abstract

Abstract A fat blend having a relatively low level of trans fatty acids, which is preferably lower than 10% is obtained by random interesterification of lauric fats, saturated fats and a minor proportion of partially hydrogenated fats. A good melting behaviour in the mouth is achieved without recourse to fractionation.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 132 words
A fat blend comprising a mixture of triglycerides wherein lauric acid is present at a level ranging from 5-20 wt%, the sum of the levels of palmitic acid and stearic acid ranges from 18-40 wt%, the level of oleic acid ranges from 19-35 wt%, the level of unsaturated fatty acids in the transconfiguration is less than 15 wt% and the level of linoleic acid ranges from 18-35 wt%, up to 5 wt% of the mixture consisting of triglycerides (i) from 3 saturated fatty acids containing 16 or 18 C-atoms and at least 9 wt% of the mixture consisting of triglycerides (ii) from 2 saturated C 16 - or C 18 -fatty acids and 1 cis unsaturated C 16 - or C 18 -fatty acid, at least 50% of triglycerides (ii) being asymmetrical.
Claim 2
Dependent Claim 132 words
A fat blend comprising a mixture of triglycerides wherein lauric acid is present at a level ranging from 5-20 wt%, the sum of the levels of palmitic acid and stearic acid ranges from 18-40 wt%, the level of oleic acid ranges from 19-35 wt%, the level of unsaturated fatty acids in the transconfiguration is less than 15 wt% and the level of linoleic acid ranges from 18-35 wt%, up to 5 wt% of the mixture consisting of triglycerides (i) from 3 saturated fatty acids containing 16 or 18 C-atoms and at least 9 wt% of the mixture consisting of triglycerides (ii) from 2 saturated C 16 - or C 18 -fatty acids and 1 cis unsaturated C 16 - or C 18 -fatty acid, at least 50% of triglycerides (ii) being asymmetrical.
Claim 3
Dependent Claim 17 words
A fat blend according to claim 1, wherein 10-20 wt% of the mixture consists of triglycerides (ii).
Claim 4
Dependent Claim 22 words
A fat blend according to claim 1, wherein the level of unsaturated fatty acids in the trans configuration is less than 10%.
Claim 5
Dependent Claim 45 words
A fat blend according to claim 1, wherein the mixture of triglycerides have the following carbon number profile: C 38 =1-6 C 40 =2-4 C 42 =3-8 C 44 =3-8 C 46 =4-12 C 48 =8-20 C 50 =7-14 C 52 =14-22 C 54 =18-40.
Claim 6
Dependent Claim 30 words
A fat blend according to claim 1, have the following fat solid profile determined by nuclear magnetic resonance: N 10 =25-55 N 20 =10-25 N 30 =0-6 N 35 =0-2.5.
Claim 7
Dependent Claim 14 words
A fat blend according to claim 1, which is substantially free from fractionated fats.
Claim 8
Dependent Claim 16 words
A fat blend according to claim 1, which contains less than 20 wt% partially hydrogenated fat.
Claim 9
Dependent Claim 96 words
A fat blend according to claim 1 wherein the mixture of triglycerides is obtained by random interesterification of a fat (a) rich in cis-mono-di- and/or polyunsaturated fatty acids, a substantially saturated fat (b) having an iodine value not exceeding 10 consisting of triglycerides essentially from C 16 - and/or C 18 -fatty acids, a fat (c) rich in saturated C 12 - and/or C 14 -fatty acids and 0-35 wt% of a fat (d) having a melting point ranging from 25°-60° C., and 0-50 wt% of a non-interesterified fat (a), (c) or (d) or mixtures thereof.
Claim 10
Dependent Claim 83 words
A fat blend according to claim 8, wherein fat (a) is selected from the group consisting of sunflower-, soybean-, rapeseed-, maize-, safflower- and peanut oil, fat (b) is selected from the group consisting of substantially fully hydrogenated sunflower-, soybean-, rapeseed-, maize-, safflower-, peanut- and palm oil, fat (c) is selected from the group consisting of coconut-, palmkernel-, babassu-, tucum-, and ouricurum fat and fat (d) is selected from the group consisting of palm oil, partially hydrogenated palm oil and partially hydrogenated fat (a).
Claim 11
Dependent Claim 81 words
A fat blend according to claim 8, wherein the mixture of triglycerides is obtained by random interesterification of 20-50 wt% fat (d), said interesterified mixture constituting 50-100 wt% of the total fat blend and (ii) a non-interesterified fat consisting of up to 40 wt% fat (a) or up to 25 wt% fat (c) or up to 35 wt% fat (d), or mixtures thereof, said non-interesterified fat or mixtures of these fats constituting up to 50 wt% of the total fat blend.
Claim 12
Dependent Claim 27 words

Claim 14
Dependent Claim 26 words
Water-in-oil emulsions of the margarine and reduced fat spread types, wherein the fat phase contains a fat blend as claimed in any one of claims 1-11.
