摘要
玉米淀粉经过酸、酶等催化水解后,再经过溶解、过滤、结晶、洗涤及干燥等步骤,可得到微晶淀粉。X-射线衍射分析表明,随着结晶温度的升高、结晶浓度的增大,微晶的晶型从B型向A型转化;短链淀粉有利于形成A型结构,而长链淀粉倾向于形成B型结构。
The crystallite corn starch can be obtained from corn starch through a sequent of treatment： hydrolyzed by acid and （or） enzyme, then followed by dissolution, filtration, crystallization, washing, and air drying. The X - ray diffraction analysis results show that the types of the crystallite starch transformed from B - type to A - type with rising of temperature and concentration. Shorter chain starch is favorable to form A - type crystallite ; while longer chains starch is favorable to form B -type crystallite.
