Title
(EN) PRODUCTION OF DEGUMMED FATTY ACID ALKYL ESTERS
(FR) PRODUCTION D'ESTERS ALKYLIQUES D'ACIDES GRAS DEMUCILAGINES
Abstract
(EN) The present invention relates to a method for producing fatty acid alkyl esters, such as fatty acid methyl esters (FAME) and fatty acid ethyl esters with a low level of impurities such as phospholipids. The method of the invention is simplified by combining two process steps into one single process step and is therefore economically cheaper. The method includes mixing water, alcohol, triglyceride and/or free fatty acids a lipolytic enzyme and a phospholipase. Subsequently the aqueous phase, which contains glycerine, residual enzyme and most of the hydrolyzed phospholipids, is separated from the non-aqueous phase, whereby the content of phospholipids in the non-aqueous phase is reduced.
(FR) La présente invention concerne un procédé destiné à produire des esters alkyliques d'acides gras, tels que des esters méthyliques d'acides gras (FAME) et des esters éthyliques d'acides gras présentant un faible taux d'impuretés, et notamment de phospholipides. Le procédé de l'invention est simplifié par combinaison de deux étapes de procédé en une étape de procédé unique. Par conséquent, il est économiquement avantageux. Ledit procédé consiste à mélanger de l'eau, de l'alcool, un triglycéride et/ou des acides gras libres, une enzyme lipolytique et une phospholipase. Ensuite, la phase aqueuse, qui contient une glycérine, une enzyme résiduelle et la plupart des phospholipides hydrolysés, est séparée de la phase non aqueuse, ce qui permet de réduire la teneur en phospholipides dans la phase non aqueuse.
