Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
77 words
A blend of (I) non-lauric coating fats comprising a mid-fraction of the wet fractionation of fat mixtures containing hardened soybean oil and (II) liquid, trans-hardened high-stability oils comprising the olein-fraction of the wet fractionation of mixtures containing soybean oil, wherein the weight ratio of I:II ranges from 90:10 to 70:30 and wherein the Rancimat Induction Period value of the blend is more than calculated from the Rancimat Induction Period values of the individual components of the blend.
Claim 2
Dependent Claim
77 words
A blend of (I) non-lauric coating fats comprising a mid-fraction of the wet fractionation of fat mixtures containing hardened soybean oil and (II) liquid, trans-hardened high-stability oils comprising the olein-fraction of the wet fractionation of mixtures containing soybean oil, wherein the weight ratio of I:II ranges from 90:10 to 70:30 and wherein the Rancimat Induction Period value of the blend is more than calculated from the Rancimat Induction Period values of the individual components of the blend.
Claim 3
Dependent Claim
33 words
A blend according to claim 1, wherein the mixture containing hardened soybean oil also comprises at least one member from the group consisting of hardened, wet-fractionated palm oil olein and hardened cottonseed oil.
Claim 4
Dependent Claim
50 words
A blend according to claim 2, wherein the mixture containing hardened soybean oil comprises at least one member from the group consisting of hardened, wet-fractionated palm oil olein and hardened cottonseed oil in an amount such that the weight ratio of hardened soybean oil: said member is 90:10 to 10:90.
Claim 5
Dependent Claim
26 words
A blend according to claim 1, wherein the liquid, trans-hardened, high-stability oils (II) are olein fractions of the wet fractionation of mixtures containing hardened soybean oil.
Claim 6
Dependent Claim
31 words
A blend according to claim 4, wherein the mixtures containing hardened soybean oil also comprise a member of the group consisting of hardened, wet-fractionated palm oil olein and hardened cottonseed oil.
Claim 7
Dependent Claim
24 words
A blend according to claim 1 wherein the components (I) and (II) originate from the same wet fractionation of mixtures containing hardened soybean oil.
Claim 8
Dependent Claim
24 words
A blend according to claim 1 wherein the components (I) and (II) originate from a different wet fractionation of mixtures containing hardened soybean oil.
Claim 9
Dependent Claim
16 words
A blend according to claim 1 wherein the ratio of I:II ranges from 90:10 to 80:20.
Claim 10
Dependent Claim
32 words
A blend according to claim 1 wherein (I) has a relatively low Rancimat Induction Period value and (II) has a Rancimat Induction Period value of more than 50 hours at 120° C.
Claim 11
Dependent Claim
13 words
A blend according to claim 1 wherein the ratio of I:II is 80:20-70:30.
Claim 12
Dependent Claim
86 words
Process for the preparation of a blend of non-lauric coating fats and liquid, trans-hardened, high-stability oil, wherein soybean oil or soybean oil mixed with a least one member of the group consisting of wet-fractionated palm oil olein and cottonseed oil, is hardened catalytically, whereupon the hardened product is wet-fractionated and separated into a hard stearin fraction, a mid-fraction and an olein fraction after which the mid-fraction as non-lauric coating fat is blended with part of an olein fraction from the same or a different wet fractionation.
Claim 13
Dependent Claim
86 words
Process for the preparation of a blend of non-lauric coating fats and liquid, trans-hardened, high-stability oil, wherein soybean oil or soybean oil mixed with a least one member of the group consisting of wet-fractionated palm oil olein and cottonseed oil, is hardened catalytically, whereupon the hardened product is wet-fractionated and separated into a hard stearin fraction, a mid-fraction and an olein fraction after which the mid-fraction as non-lauric coating fat is blended with part of an olein fraction from the same or a different wet fractionation.
Claim 14
Dependent Claim
15 words
Process according to claim 11, wherein the hardening is carried out with a sulphided Ni-catalyst.
Claim 15
Dependent Claim
29 words
Process according to claim 12, wherein the wet fractionation is carried out with acetone in a ratio of more than 3 volume units acetone per weight unit of oil.
Claim 16
Dependent Claim
16 words
Chocolate coatings having an improved oxidation stability, which contain a fat blend according to claim 1.
Claim 17
Dependent Claim
10 words
Food products containing a chocolate coating according to claim 14.
