This invention provides a process for forming fatty acid esters of C<SUB>1-4 </SUB>alkyl alcohols by alkaline transesterification of a glyceride oil, comprising the steps of: (a) providing a glyceride oil with a free fatty acid content below 2% more preferably below 0.5 weight % expressed as oleic acid; (b) mixing said glyceride oil with at least a part of one or more alcoholic phases originating from the alkaline transesterification as referred to above; (c) separating the mixture thus formed into a heavy, alcoholic phase and a light, pre-treated fatty phase; and (d) transesterifying said pre-treated fatty phase with said C<SUB>1-4 </SUB>alkyl alcohols. The transesterified product can be used in biodiesel production.
