Method for modification of fats and oils

Takaharu Matsuo, +3 more
TLDR
In this paper, a method of the modification of a fat or oil wherein a mixture (mixture A) containing a glyceride-type fat or oils to be modified (material A) and a fatty acid or a nonglyceride type ester thereof (material B) is selectively transesterified in the presence of a catalyst having a selective transesterification activity (catalyst A); the resulting fat and oil (resultant A), fatty acid and catalyst are recovered from the reaction mixture; and then a hard butter is produced from the resultant A, the improvement
Abstract: 
In a method of the modification of a fat or oil wherein a mixture (mixture A) containing a glyceride-type fat or oil to be modified (material A) and a fatty acid or a nonglyceride-type ester thereof (material B) is selectively transesterified in the presence of a catalyst having a selective transesterification activity (catalyst A); the resulting fat or oil (resultant A), fatty acid or nonglyceride-type ester thereof (resultant B) and catalyst are recovered from the reaction mixture; and then a hard butter is produced from the resultant A, the improvement comprises hydrogenating a part or all of the resultant B and reusing the hydrogenated product as a part of the mixture A.

Enzymatic method for preparing transesterified oils

Peter H. Brown, +9 more
TL;DR: In this article, an enzymatic transesterification method for preparing a margarine oil having both low trans- acid and low intermediate chain fatty acid content is disclosed, which includes the steps of providing a reaction mixture containing a stearic acid source material and an edible liquid vegetable oil.

Integrated chemical processes for industrial utilization of seed oils

Zenon Lysenko, +11 more
TL;DR: In this paper, an integrated process of preparing industrial chemicals starting from seed oil feedstock compositions containing one or more unsaturated fatty acids or unsaturated acid esters, which are essentially free of metathesis catalyst poisons, particularly hydroperoxides, was described.

Enzymatic treatment of edible oils

Erik Aalrust, +5 more
TL;DR: In this article, the content of phosphorus-containing components and the iron content of an edible vegetable or animal oil, preferably an oil such as soybean oil which has been wet-refined to remove mucilage, are reduced by enzymatic decomposition by contacting the oil with an aqueous solution of phospholipases A 1, A 2, or B and then separating from the treated oil.

Metathesis of unsaturated fatty acid esters or unsaturated fatty acids with lower olefins

Thomas H. Newman, +5 more
TL;DR: An olefin metathesis process involving contacting an unsaturated fatty acid ester or unsaturated fat acid, such as methyl-9decenoate or 9decenoic acid, with a lower ole finetext, is discussed in this article.

Process for the synthesis of unsaturated alcohols

Bob R. Maughon, +2 more
TL;DR: In this article, a process of preparing an unsaturated alcohol (olefin alcohol), such as, a homo-allylic mono-alcohol or homoallylic polyol, involving protecting a hydroxy-substituted unsaturated fatty acid or fatty acid ester, such as methyl ricinoleate, derived from a seed oil, to form a hydrooxy-protected unsaturated acids or esters, is described.

Fat process and composition

Michael Herder Coleman, +1 more
TL;DR: In this article, the Disclosure Fats and glyceride oils especially for edible purposes are improved by an esterification reaction in the presence as catalyst of n lipaso enzyme with a small amount of water to activate the enzyme, which may be selective in?etion, to replace fatty acid radicals on the glycerides molecules by others.

Method for producing cacao butter substitute

Takaharu Matsuo, +2 more
TL;DR: In this article, a method for producing a cacao butter substitute by transesterification of fats and oils containing glycerides rich in the oleyl moiety at the 2-position with an alcohol ester of stearic acid and/or palmitic acid in the presence of a lipase having reaction specificity to the 1,3position of triglycerides and not more than 18% by weight of water based on the total weight of the reaction mixture is provided.
