Abstract
Abstract A margarine fat with a low level of triglycerides from fatty acids in the trans-configuration is produced from vegetable oils, and preferably from one type of oil, by a process involving (a) random interesterification of a saturated fat with an unsaturated oil, (b) fractionation of the interesterified mixture to remove high melting components (stearin) and (c) optionally mixing appropriate amounts of the low melting components (olein), interesterified mixture and non-hydrogenated or partly hydrogenated oils.

Claim 1
Independent Claim
190 words
A process for producing a margarine fat comprising: (a) randomly interesterifying a mixture consisting of 35-84 wt.% of an oil (i) comprising an oil in which at least 20% of the fatty acid residues consist of linoleic acid and 16-65% of a fat (ii) in which at least 80% of the fatty acid residues are saturated and have a chain length of at least 16 carbon atoms, to obtain an interesterified mixture (A); (b) fractionating interesterified mixture (A) at a temperature such as to yield a higher-melting stearin fraction which is enriched in triglycerides from trisaturated fatty acid residues and a lower-melting olein fraction (B) in which the level of triglycerides from trisaturated fatty acids ranges from 0 to 6%, based on the total mixture; (c) mixing 20 to 100% of said olefin fraction (B) with 5 to 50% of the interesterified mixture (A) and 5 to 55% of an oil (C) comprising an oil which is substantially free from crystallized fat at 10° C., or a mixture of said oil with an oil having a melting point ranging from 28° to 43° C., the sum of A+B+C being 100%.
