SOLID FAT TRIGLYCERIDE COMPOSITION
The invention pertains to a process for the preparation of a fat comprising enzymatic transesterification of an oil with a fatty acid mixture having more than 80 wt. % fatty acids of the H type to provide a triglyceride mixture containing more than 60% saturated fatty acids and with a high degree of saturation on the 2-position and a triglyceride mixture obtained thereby.
1 . Method for the preparation of a fat comprising the steps of
a. providing an oil;
b. providing a fatty acid mixture having more than 80 wt. % fatty acids of the H type drawn on the fatty acid mixture;
c. subjecting the oil with the fatty acid mixture to enzymatic transesterification to provide a fat mixture comprising
i. a triglyceride mixture, which triglyceride mixture contains more than 60% saturated fatty acids drawn on the total amount of fatty acids in the triglyceride mixture, and, optionally
ii. free fatty acids;
d. optionally, removing free fatty acids from the fat mixture;
e. optionally, isolating the triglyceride mixture.
2 . Method according to claim 1 , wherein the oil is an edible oil, preferably a vegetable oil, preferably not palm oil or palm oil-based or palm oil-derived fractions.
3 . Method according to claims 1 - 2 , wherein the oil is non-hydrogenated.
4 . Method according to claims 1 - 3 , wherein the fatty acid mixture contains more than 90 wt. % of C18:0 fatty acid (stearic acid).
5 . Method according to claims 1 - 4 , wherein the ratio of the fatty acid mixture to oil is more than 1.5, based on weight equivalents.
6 . Method according to claims 1 - 5 , wherein the transesterification is a one-step transesterification or a two-step transesterification.
7 . Method according to claims 1 - 6 , wherein the triglyceride mixture comprises more than 70 wt. % of saturated fatty acids drawn on the total amount of fatty acids in the triglyceride mixture.
8 . Method according to claims 1 - 7 , wherein the triglyceride mixture comprises triglycerides of the StStSt type in an amount of more than 30% by weight drawn on the total amount of triglycerides in the triglyceride mixture.
9 . Method according to claims 1 - 8 , wherein the ratio (StStSt+StStU)/(StStSt+StStU+StUU) in the triglyceride mixture is more than 0.70.
10 . Method according to claims 1 - 10 , wherein in the triglyceride mixture 60% of the fatty acids at the 2-position of the triglyceride is of the C18:0-type.
11 . Triglyceride mixture obtainable by the method of any of the claims 1 - 10 .
12 . Triglyceride mixture according to claim 11 , wherein the ratio (StStSt+StStU)/(StStSt+StStU+StUU) in the triglyceride mixture is more than 0.70.
13 . Triglyceride mixture according to claims 11 - 12 , wherein in the triglyceride mixture 50% of the fatty acids at the 2-position of the triglyceride is of the H-type, preferably of the C18:0-type.
14 . Triglyceride mixture according to claims 11 - 13 , wherein in the triglyceride mixture has an SFC profile of
