PROCESS FOR PRODUCING PROCESSED GLYCERIDE FAT
Document Type and Number:
WIPO Patent Application WO/2003/000832
Kind Code:
A1
Abstract:
A process for producing a processed glyceride having a satisfactory color tone and having a high purity without the need of a fractionation step, by mitigating the deterioration in color tone caused by the processing and circulatory use of fatty acid esters recovered after transesterification. The process comprises subjecting a glyceride fat and fatty acid esters and&sol or free fatty acids to transesterification, distilling the reaction product to recover part or all of the fatty acid esters and&sol or free fatty acids, subjecting the distillation fraction recovered to hydrogenation and to redistillation or mixing with fresh fatty acid esters and&sol or fresh free fatty acids in any order, rereacting the resultant fraction or mixture with the distillation residue, and separating a fat fraction from the final reaction product, and is characterized in that the content of the ingredients other than the fatty acid esters and&sol or free fatty acids is regulated to 3.0 wt.% or lower.
