Abstract
The object of an aspect of the present invention is to provide a method for producing a long-chain fatty acid, the method making it possible to prevent a coloring component from being contained in the long-chain fatty acid and recover the long-chain fatty acid at a high yield. The above problem is solved by providing a method for producing a long-chain fatty acid, the method including the steps of: (a) with use of an enzyme, decomposing, into fatty acids, triglyceride contained in a raw vegetable oil which is derived from a vegetable-derived oil-containing waste; (b) removing, by distillation, a short-chain fatty acid contained in the raw vegetable oil which has been subjected to the step (a); and (c) recovering, by short-path distillation, a long-chain fatty acid contained in the raw vegetable oil which has been subjected to the step (b).
