Title:
METHOD FOR PRODUCING HYDROGENATED FAT OR OIL
Document Type and Number:
WIPO Patent Application WO/2011/099345
Kind Code:
A1
Abstract:
Disclosed are a method for producing a hydrogenated fat or oil, whereby, in hydrogenating a fat or oil containing a polyvalent unsaturated fatty acid, the formation of a trans acid is minimized to improve the oxidation stability of the fat or oil, and a production device therefor. Specifically disclosed is a method for producing a hydrogenated fat or oil comprising hydrogenating a fat or oil containing a polyvalent unsaturated fatty acid in the presence of a nickel catalyst, wherein the hydrogenation is conducted at a reaction temperature of 60-75oC, and the fat/oil temperature-increasing ratio per unit of iodine value lowered by the aforesaid hydrogenation is regulated to 0.5 or below by controlling either or both of the heat amount for cooling and the hydrogen amount supplied to the hydrogenation system so that the amount of a trans acid formed per unit of iodine value lowered by the aforesaid hydrogenation is adjusted to 0.25 wt%. The regulation is conducted by controlling the operation of a circulating pump (17) and the operation of a flow rate-adjusting valve (15) by an electronic controller (11) based on the data of the temperature in a reaction container (7) and the data of the pressure in a hydrogen supply channel (6).
