| 摘 要： | 首次将爆米花机用于稻壳的预处理,与3%NaOH、3%氨水、3%H2SO4、5%氨水煮沸处理以及微波处理法比较。结果表明,相对于未处理稻壳,经以上方法处理后的稻壳酶解率分别提高了258.50%、395.55%、177.53%、168.62%、130.16%、50.61%。其中爆米花机处理法因爆稻壳是爆谷花的副产物而相对成本低,且绿色环保,因而是一种可放大到工业化生产的预处理方法。

| Abstract: | Popcorn machine was first used to pretreat rice husk and was compared with the following methods,including:3% NaOH;3% NH3.H2O;3% H2SO4;boiled in 5% NH3.H2O;microwave.The main components of the pretreated rice husk were determined and analyzed the rice husk with SEM,and the total sugar content of the rice husk after enzymatic hydrolysis were compared,The results showed that the total sugar content of the rice husk after pretreated increased by 395.55%,177.53%,168.62%,130.16%,50.61%,258.50%,respectively.The blast rice husk,as a by-product of blast rice,was produced with a relative low cost,and did little damage to the environment.So blasting rice husk with an improve popcorn machine is a promising method to industry. |
