摘要: 以玉米淀粉为原料,采用酶解-热醇协同处理制备一种新型的淀粉基吸附材料.利用比表面积孔隙分析仪、扫描电子显微镜对该吸附材料的比表面积、颗粒形貌特征进行表征,并考察该吸附材料的吸水性能和吸油性能.结果表明,淀粉颗粒经酶解-热醇协同处理后,淀粉颗粒上形成许多孔洞,结构松散,比表面积、孔的直径和孔的容积增大;淀粉颗粒经协同处理后,被赋予了良好的吸附性能,当酶添加量为0.9%时,其吸水率是原淀粉的5.1倍,吸油率是原淀粉的1.9倍.

Abstract:

A novel starch-based absorption material was prepared via enzymolysis and heated-ethanol co-processing,with corn starch as the material.The specific surface area,morphology of the product were then characterized by using a pore surface area analyzer and a scanning electron microscope,and the capabilities of water absorption and oil absorption of the product were investigated.The results show that,after the co-processing,many holes form in starch granules,and the granules become loose,with increases in the specific surface area,the hole diameter and the hole volume.Moreover,it is indicated that the starch granules after the co-processing are of excellent absorption property.For example,at an enzyme dosage of 0.9%,its water absorption and oil absorption are respectively 5.1 and 1.9 times those of the native corn starch.
