Title
(EN) METHOD FOR PREPARING FATTY ACIDS BY HYDROLYZING IN SITU LIPIDS CONTAINED IN A PLANT SEEDS
(FR) PROCEDE DE PREPARATION D'ACIDES GRAS PAR HYDROLYSE IN SITU DES LIPIDES CONTENUS DANS LES GRAINES D'UNE PLANTE
Abstract
(EN)
The invention concerns a method for preparing fatty acids by hydrolyzing in situ lipids contained in a plant seeds, characterized in that it comprises the following steps: a) grinding the seeds in aqueous medium until a suspension of solid particles with a diameter less than 500 $g(m)m is obtained; b) adding an exogenous lipase into the suspension obtained in step a); c) homogenizing the suspension containing the lipase until a homogenate consisting of an emulsion of the lipids initially contained in the seeds, mixed with the solid particles of the seeds, is obtained; d) hydrolyzing the lipids contained in the homogenate obtained in step c) at a temperature ranging between 15 °C and 55 °C, for a time interval ranging between 15 minutes and 5 hours; e) recovering the fatty acids resulting from hydrolysis of the lipids carried out in step d).
