摘  要:
本试验以蜡质玉米淀粉为原料,以环氧氯丙烷为交联剂,在碱性条件下制备蜡质玉米交联淀粉。采用二次回归正交组合设计,以交联度为试验指标,利用回归与方差分析,得到最佳工艺条件:氢氧化钠用量X1=0.872g,环氧氯丙烷用量X2=0.5 mL,反应温度X3=53.6℃,反应时间X4=2.64 h;建立二次回归方程,并进行验证试验。

摘  要:
In this experiment,cross-linked waxy corn starch were prepared with waxy corn starch as raw material,with epichlorohydrin as cross-linking agent under alkaline conditions using chemically modified method.Quadratic regression orthogonal combination experiments design was applied with cross-linking degree as test indexes,then the data were analyzed by regression and ANOVA based on above-mentioned experimental results and variance analysis to obtain the optimal preparation conditions,i.e.,dosage of sodium hydroxide X1= 0.872 g,dosage of epoxy chloropropane X2= 0.5 mL,reaction temperature X3= 53.6℃,the reaction time X4 = 2.64 h.Optimal regression equations were established,and verification experiments were carried out.
