The present invention provides improved processes for methanolysis and ethanolysis of fatty acid glycerides such as those found in naturally occurring fats and oils derived from plants and animals. The processes comprise solubilizing an oil or fat in methanol or ethanol by the addition of a cosolvent in order to form a one phase reaction mixture, and adding an esterification catalyst. The processes proceed quickly, usually in less than 20 minutes, at ambient temperatures, atmospheric pressure, and without agitation. The cosolvent increases the rate of the reaction by making the oil soluble in the methanol, thus increasing contact of the reactants. The lower alkyl fatty acid monoesters produced by the processes can be used as biofuels and are suitable as diesel fuel replacements or additives.
