摘要: 研究了β-环糊精对骨胶除臭的最佳工艺条件。以骨胶为原料,在单因素试验的基础上,以β-环糊精用量、反应时间、反应温度及搅拌速率为自变量,骨胶的气味、黏度为响应值,根据Box-Benhnken 试验设计原理,采用四因素三水平的分析法模拟得到二次多项式回归方程的预测模型,优化骨胶的除臭工艺。回归模型具有高度显著性,方程对试验拟合较好,可以对骨胶的气味、黏度进行很好的分析和预测,得出各因素对气味、黏度的影响大小,响应面分析图表明搅拌速率和反应时间的相互作用对黏度的影响显著;结果显示骨胶除臭的最佳优化条件为β-环糊精的用量为骨胶质量的6.3%,反应温度45.7℃,反应时间为90min,搅拌速率300r/min;优化后的骨胶气味良好,黏度为8.9Pa·s;实测值与预测值的相对误差较小,说明最佳优化工艺的可靠性较高。

Abstract: The objective of this study is to optimize deodorization conditions for industrial bone glue with β-cyclodextrin.Residues from bone glue were used in this paper.On the basis of single-factor test,the response surface methodology was utilized to investigate the effects of β-cyclodextrin content,reaction time,reaction temperature and stirring rate.The odor and viscosity of the bone glue were chosen as response value.The regression model had a high significance level,and the established regression equations fit with experimental results well and showed good prediction for the odor and viscosity value of bone glue.The influences of each factor on the smell and viscosity were obtained.The response surface plots showed that the interaction between stirring rate and reaction time was outstanding.The results showed that the optimal conditions for deodorization of β-cyclodextrin content was 6.3% of bone glue amount,reaction temperature of 45.7℃,reaction time of 90min,stirring rate of 300r/min.The bone glue after optimized deodorization process had a good smell and a viscosity of 8.9 Pa·s.The relative error between the measured value and the predicted value is small,which indicates that the reliability of the optimal optimization process is high.

Key words: bone glue, response surface, β-cyclodextrin, deodorization
