摘要/Abstract

摘要： 本研究采用稀硫酸对热研4号王草进行预处理,结合3,5-二硝基水杨酸法测定水解液中还原糖含量的方法,对稀硫酸浓度(v/v)、固液比(g/mL)、水解温度、水解时间和不同粒径5个因素进行单因素实验分析,在单因素试验的基础上通过二次回归正交旋转组合设计进行工艺参数优化。实验结果表明,最佳预处理条件,水解温度为117℃,水解时间为15 min,稀硫酸浓度为3%,固液比为1∶15,粒径为0.425~0.850 mm。

Abstract: Pennisetum purpureum×P. typhoideum cv. Reyan No.4 was pretreated by the dilute acid method and reducing sugars in the hydrolysate was measured by the DNS method. After separate analysis on sulfuric acid concentration (v/v), solid-to-liquid ratio(g/mL), hydrolysis temperature, hydrolysis time and the different granularity, the optimum pretreatment conditions were obtained by the quadratic general rotary unitized design. The optimum pretreatment conditions were a hydrolyzing temperature of 117℃ for 15 min with 3% (H₂SO₄), a solid-to-liquid ratio of 1∶15 and a granularity of 0.425-0.850 mm.
