Abstract:
1. A method of producing fatty acid alkyl esters containing 0.1 wt % or less triglyceride, at least comprising: (A) a step of removing at least water from an oil/fat raw material to a water content in the oil/fat raw material, as determined by Karl-Fischer volumetric titration, of 0.03 wt % or less; and (B) a step of converting fatty acid glycerides contained in the oil/fat raw material into fatty acid alkyl esters in the presence of an alkali catalyst and alcohols and reducing triglyceride content in the fatty acid alkyl esters obtained to 0.1 wt % or less by using a static mixing means at a linear velocity of 1.4 m/sec or more, and wherein the alcohols are used in an amount of 5 moles or less with respect to 1 mole of the oil/fat raw material in the step (B).
