Title (EN) CAFFEINE PRODUCTION METHOD
(FR) PROCÉDÉ DE PRODUCTION DE CAFÉINE
Abstract:
(EN) The present invention provides a method for producing caffeine, wherein the method comprises: (a) combining a coffee extract comprising caffeine with an aqueous organic acid; (b) crystallizing the coffee extract and the aqueous organic acid so as to form caffeine-organic acid co-crystals in an aqueous phase; (c) separating the caffeine-organic acid co-crystals from the aqueous phase; and (d) extracting caffeine from the co-crystals obtained in step (c), wherein step (d) comprises placing the co-crystals in an aqueous solution so as to form a caffeine precipitate and a solution comprising the organic acid. Also provided is a method for producing a decaffeinated coffee extract comprising chlorogenic acids.
(FR) La présente invention concerne un procédé de production de caféine, le procédé comprenant : (a) la combinaison d'un extrait de café comprenant de la caféine avec un acide organique aqueux ; (b) la cristallisation de l'extrait de café et de l'acide organique aqueux afin de former des co-cristaux de caféine-acide organique en phase aqueuse ; (c) la séparation des co-cristaux de caféine-acide organique de la phase aqueuse ; et (d) l’extraction de la caféine des co-cristaux obtenus à l'étape (c), l'étape (d) comprenant le dépôt des co-cristaux dans une solution aqueuse afin de former un précipité de caféine et une solution comprenant l'acide organique. L'invention concerne également un procédé de production d'un extrait de café décaféiné comprenant des acides chlorogéniques.
