【 摘 要 】

References(19)Cited-By(1)Corn grains are pulverized by steam explosion after 40 min cooking at 533 K, and the products are further hydrolyzed under hydrothermal conditions. Residual solids consisting of particles having average diameter of 89 μm are obtained by steam explosion, and about 50–60 wt%(C/C) on carbon weight basis of initial sample is converted into water soluble (WS) components. The steam exploded products are further hydrothermally degraded in a small batch reactor at 453 to 493 K. The yields of WS components are almost unchanged with time at 453 and 473 K, but the molecular weights significantly decrease to lower than 1000.
