Abstract
Abstract The invention relates to natural fat blends which are substantially free of hydrogenated and interesterified fats and can be used for producing margarines which are packaged in wrappers. The blends comprise (i) a specific stearin obtained by fractionation of oils and fats derived from fatty acids with an average chain length ranging from 12 to 18 carbon atoms and (ii) oils and fats derived from fatty acids with a chain length ranging from 12 to 14 carbon atoms.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
170 words
Fat blend, which is substantially free of hydrogenated and interesterified fats, comprising: (i) 60 to 98% of an oil or fat having a slip melting point not exceeding 43° C.; and (ii) 2 to 40% of a stearin of oils or fats having an average chain length of the fatty acid radicals of 12 to 18 carbon atoms, said stearin having a slip melting point exceeding 30° C.; in which fat blend the proportion of glycerides having trisaturated fatty acids with a chain length of 12 to 14 carbon atoms ranges from 7 to 14% and the proportion of glycerides having trisaturaed fatty acids with an average chain length of 16 to 18 carbon atom ranges from 7 to 12%; and which fat blend has an amount of solid phase as determined by pulsed nuclear magnetic resonance of: N 10 greater than or equal to 15% N 20 greater than or equal to 6.5% N 30 smaller than or equal to 5% N 35 smaller than or equal to 3%.
Claim 2
Dependent Claim
170 words
Fat blend, which is substantially free of hydrogenated and interesterified fats, comprising: (i) 60 to 98% of an oil or fat having a slip melting point not exceeding 43° C.; and (ii) 2 to 40% of a stearin of oils or fats having an average chain length of the fatty acid radicals of 12 to 18 carbon atoms, said stearin having a slip melting point exceeding 30° C.; in which fat blend the proportion of glycerides having trisaturated fatty acids with a chain length of 12 to 14 carbon atoms ranges from 7 to 14% and the proportion of glycerides having trisaturaed fatty acids with an average chain length of 16 to 18 carbon atom ranges from 7 to 12%; and which fat blend has an amount of solid phase as determined by pulsed nuclear magnetic resonance of: N 10 greater than or equal to 15% N 20 greater than or equal to 6.5% N 30 smaller than or equal to 5% N 35 smaller than or equal to 3%.
Claim 3
Dependent Claim
43 words
Fat blend according to claim 1 further comprising triglycerides having two saturated fatty acids with a chain length of 12 to 18 carbon atoms and one unsaturated fatty acid with a chain length of 16-18 carbon atoms in amounts from 18 to 30%.
Claim 4
Dependent Claim
44 words
Fat blend according to claim 1, further comprising triglycerides having one saturated fatty acid with a chain length of 12 to 18 carbon atoms and two unsaturated fatty acids with a chain length of 16 to 18 carbons in amounts from 20 to 35%.
Claim 5
Dependent Claim
47 words
Fat blend according to claim 1, in which the oil or fat having a slip melting point not exceeding 43° C. is selected from the group consisting of palm oil, tallow, lard, oils which are rich in lauric acid and oils which are liquid at room temperature.
Claim 6
Dependent Claim
19 words
Fat blend according to claim 1, in which the stearin consists of palm kernel oil and palm oil stearin.
Claim 7
Dependent Claim
73 words
Fat blend according to claim 1, which comprises (a) 2-40% by weight of stearins (b) 0-25% by weight of non-fractionated lauric acid containing fats selected from the group consisting of coconut-, palm kernel- and babassu oil (c) 25-65% by weight of non-fractionated oils which are rich in fatty acids of a chain length ranging from 16 to 18 carbon atoms (d) 20-50% by weight of an oil which is liquid at room temperature.
Claim 8
Dependent Claim
59 words
Fat blend according to claim 6, which comprises: (a) 2-20% by weight of stearins (b) 5-20% by weight of non-fractionated lauric acid-containing fats (c) 30-45% by weight of non-fractionated oil with a relatively high content of fatty acids having a chain length of 16 to 18 carbon atoms (d) 30-50% of an oil which is liquid at room temperature.
Claim 9
Dependent Claim
19 words
Margarines and low fat spreads in which the fat phase contains a fat blend as claimed in claim 1.
