Abstract
A process including at least one reactive trituration step which includes putting an oil cake including from 3% to 30% oil in contact with an anhydrous light alcohol and an alkaline catalyst under temperature and time conditions that are sufficient to allow for the extraction and transesterification of the vegetable oil and lead to the production of a mixture including fatty acid esters and glycerol, and a de-oiled cake including less than 3% oil. Also, a detoxified de-oiled cake as well as to a mixture of fatty acid esters with improved stability and resistance to oxidation.
