Abstract
Official abstract text for this publication.
An object of the present invention is to provide a method in which a fat and/or oil is produced by a transesterification reaction using a lipase. Specifically, the present invention relates to a method for producing a transesterified fat and/or oil, comprising: (1) a low-temperature clay treatment step of bringing a fat and/or oil and a clay into contact with each other at 30 to 80° C. to obtain a reaction substrate; and (2) a step of subjecting the reaction substrate to a transesterification reaction in the presence of a lipase-containing composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a transesterified fat and/or oil, comprising: (1) a low-temperature clay treatment step of bringing a fat and/or oil and a clay into contact with each other at 30 to 80° C. in the absence of a solvent other than water and in the presence of 200 to 400 ppm of water relative to the total mass of fat and/or oil to obtain a reaction substrate; and (2) a step of subjecting the reaction substrate to a transesterification reaction in the presence of a lipase-containing composition. 2. The method according to claim 1 , wherein the fat and/or oil used in the low-temperature clay treatment step is a fat and/or oil subjected to a decolorization treatment step of performing decolorization by contact with a first clay at 90 to 150° C. 3. The method according to claim 1 , wherein in the low-temperature clay treatment step, the reaction substrate is separated from the clay after the contact with the clay. 4. The method according to claim 2 , wherein the fat and/or oil subjected to the decolorization treatment step is subjected to a deodorization step after the decolorization treatment step. 5. The method according to claim 1 , wherein the lipase-containing composition is in the form of a powder. 6. The method according to claim 1 , wherein the low-temperature clay treatment step is a step of bringing a fat and/or oil, a clay, and a fatty acid ester into contact with one another at 30 to 80° C. to obtain a reaction substrate. 7. The method according to claim 1 , wherein the low-temperature clay treatment step of bringing a fat and/or oil and a clay into contact with each other is conducted at 30 to 50° C. in the absence of a solvent other than water to obtain a reaction substrate.
