乳化香肠加工工艺条件优化

应用中心复合设计试验优化乳化香肠加工工艺条件。选取瘦肉比例、复合磷酸盐和水分添加量作为中心复合设计的因变量,总汁液损失率、弹性和红度值为应变量,利用响应面法分析进行多元线性回归和二项式拟合,并结合预测分析,得到乳化香肠的优化工艺条件。结果表明,最佳的乳化香肠加工工艺是瘦肉比例是0.7786:1、复合磷酸盐添加量0.23%、水分添加量16.45%,在此条件下的总汁液损失率为2.72%、弹性为0.865、红度值为7.318。与模型预测值偏差较小,所以该模型有良好的预测性,可以在一定程度上控制香肠的品质。

Optimization of the Processing Technology of Emulsion-type Sausages

An investigation to optimize the processing technology of emulsion-type sausages was study using central composite design involving lean ratio,compound phosphate and water as independent variables and total expressible fluid,springiness and red value a* as dependent variables.A second-order polynomial predictive model for each of the independent variables was fitted by multiple linear regression and used to predict optimum total expressible fluid,springiness and a* based on response surface analysis.The opt...
