Title
(EN) METHOD FOR PREPARING GALLIC ACID-CONTAINING COMPOSITION
(FR) PROCÉDÉ DE PRÉPARATION D'UNE COMPOSITION CONTENANT DE L'ACIDE GALLIQUE
(JA) 没食子酸含有組成物の製造方法
Abstract
(EN)
Provided is a method for preparing, from a microorganism culture solution, a gallic acid-containing composition having a low content of a protocatechuic acid. The method for producing a gallic acid-containing composition includes a step (A) for cooling and crystallizing an aqueous solution (a) containing a gallic acid and a protocatechuic acid at 0.9 °C/min or less.
(FR)
L'invention concerne un procédé de préparation, à partir d'une solution de culture de micro-organismes, d'une composition contenant de l'acide gallique ayant une faible teneur en acide protocatéchuique. Le procédé de production d'une composition contenant de l'acide gallique comprend une étape (A) pour le refroidissement et la cristallisation d'une solution aqueuse (a) contenant un acide gallique et un acide protocatéchuique à 0,9 °C/min ou moins.
(JA)
微生物培養液から、プロトカテク酸低含有率の没食子酸含有組成物を製造する方法の提供。 没食子酸及びプロトカテク酸を含む水溶液(a)を、0.9℃/min以下で冷却晶析させる工程(A)を含む、没食子酸含有組成物の製造方法。
