However, in the above-mentioned conventional method of obtaining fatty acids from the hydrolyzed liquid after hydrolyzing lipids,
There are problems that it takes a long time to hydrolyze and that the degree of purification of the product and the efficiency of separating fatty acid and glycerin are poor. In particular
The method (1) is easy to operate and inexpensive in equipment cost.
The decomposition time is as long as 18 to 24 hours, and fatty acids are easily subjected to aerial oxidation, resulting in high product coloring. In the method (3), since the fatty acid and glycerin are separated by utilizing the difference in specific gravity of taking out the fatty acid from the bottom of the decomposition tower, it is difficult to completely separate the fatty acid and glycerin. The method (4) is a method that can easily obtain a small amount of fatty acid and is used as a cosmetic raw material for the production of soap as an emulsifier.However, since the fatty acid and glycerin are separated by solvent extraction, a large-scale method is used. Industrialization is difficult and its applications are limited. Furthermore, the method (5) is also a method that has been put into practical use at present, but there are problems in reaction time, decomposition rate, enzyme production cost, and the like.
