| 摘 要： | 采用响应面分析法(RSM)研究复合塑化剂(甘油,油酸和聚乙二醇按不同比例混合)对玉米醇溶蛋白(zein)膜的延伸率的影响. 在单因素试验基础上,应用中心组合试验设计原理设计试验,以甘油、油酸和聚乙二醇为影响因素,延伸率为响应值建立二次回归方程,通过响应面分析得到其优化组合. 结果表明:复合塑化剂能显著增大zein膜的延伸率,三种塑化剂影响效果按大小排列顺序为聚乙二醇,油酸和甘油. 当甘油加入量为0. 36 g/g,油酸加入量为0. 79 g/g,聚乙二醇加入量为0. 86 g/g时,zein膜的延伸率最好,在此条件下,zein膜延伸率的理论预测值为328. 11%,验证值为326. 93%.

| Abstract: | The effect of a compound plasticizer,a mixture of glycerin,oleic acid and polyethyleneglycol,on elongation of zein films was studied by response surface methodology(RSM).Using the contents of glycerol,oleic acid and polyethylene glycol as influential factor and elongation at break(EB) as a response value,the experiments were carried out according to the Central Composite Design and the optimal values of the factors were obtained by analysis of variance(ANOVA).The results indicated that the elongation at bre... |
