Title:
バガスからのポリフェノール組成物の製造方法
Document Type and Number:
Japanese Patent JP6703562
Kind Code:
B2
Abstract:
One aspect of the present invention is a method for producing a polyphenol composition from bagasse, which comprises: a step wherein bagasse is pre-treated with use of at least one alkaline solution that is selected from the group consisting of an aqueous sodium hydroxide solution, an aqueous potassium hydroxide solution and an aqueous ammonia solution, thereby obtaining a pretreatment liquid; a step wherein after the pH of the pretreatment liquid is adjusted to an acidic value with use of hydrochloric acid, the pretreatment liquid is filtered and the filtrate is subsequently recovered; and a step wherein the filtrate is passed through a column that is filled with an aromatic synthetic adsorbent and the component adsorbed on the aromatic synthetic adsorbent is subsequently eluted by means of a mixed solvent of ethanol and water, thereby obtaining the eluted fraction as a polyphenol composition.
