Title (EN) PROCESS FOR PRODUCING POLYSACCHARIDE GUM
(FR) PROCEDE DE PRODUCTION DE GOMME GLUCIDIQUE
Abstract:
(EN) The invention provides a process for producing polysaccharide gum comprising extracting a plant material with an aqueous solvent to produce a polysaccharide gum-containing extract; contacting the extract with at least one proteolytic enzyme to at least partially digest proteins in the extract; adding an organic solvent to the extract to precipitate the polysaccharide gum; and collecting the precipitated polysaccharide gum.
(FR) L'invention concerne un procédé de production de gomme glucidique consistant à extraire une substance végétale par un solvant aqueux pour obtenir un extrait contenant de la gomme glucidique; à mettre en contact l'extrait avec au moins un enzyme protéolytique pour digérer au moins partiellement les protéines de l'extrait ; à ajouter un solvant organique à l'extrait pour précipiter la gomme glucidique et à recueillir la gomme glucidique précipitée.
