摘要： [Issues] To provide a method to produce diesel fuel that meets the standards of almost all countries in a short time.
[Solution] A method for producing diesel fuel having improved properties by mixing an aqueous enzyme solution containing 0.01 to 0.1% by weight of a lipase enzyme as a first enzyme with a water-soluble alcohol so as to be an aqueous alcohol solution having an alcohol concentration of from 20 to 35%, comprises adding a second enzyme solution in light oil having 0.001 to 0.01% by weight of pineapple-derived enzyme containing bromelain, dissolved in light oil to said base oil.
