摘要： The present invention relates to a method of efficiently producing hydroxycinnamic acids having a high quality, from a cellulose-containing biomass. More specifically, the present invention relates to a method of producing hydroxycinnamic acids, the method including the steps of: obtaining an alkaline filtrate by allowing an alkaline aqueous medium to pass through a cellulose-containing biomass; obtaining a hydroxycinnamic acid extraction liquid by allowing the alkaline filtrate to repeatedly pass through the cellulose-containing biomass; and separating the hydroxycinnamic acid from the hydroxycinnamic acid extraction liquid.

摘要： In the process of production of a sugar liquid from woody biomass, conventional techniques have a drawback in that particular components contained in the saccharified liquid of the woody biomass cause deterioration of the filtration performance during filtration of the saccharified liquid through a microfiltration membrane and/or ultrafiltration membrane. In the present invention, mannanase is reacted with a liquid component obtained by hydrolysis of woody biomass to increase the filtration performance of the microfiltration membrane and/or ultrafiltration membrane for the saccharified liquid, so that efficient production of a sugar liquid is possible.

摘要： In solid-liquid separation of a saccharified liquid by filtration through a microfiltration membrane, the filtration performance can be increased by adjusting the lignin content in a pretreated product derived from a cellulose-containing biomass to not more than 8.5% to promote formation, on the membrane surface, of a cake in which the solid component in the saccharified liquid is concentrated. Collection of the cake formed on the membrane surface allows efficient solid-liquid separation of the saccharified liquid with the microfiltration membrane.
