中文摘要: 以传统烟熏方式加工的香肠为研究对象,利用反向传播(Back-Propagation,BP)神经网络建立烟熏香肠色泽的预测模型。通过试验获得不同烟熏温度、烟熏时间和肥瘦比条件的烟熏香肠,测定其L*、a*、b*和△E值,并对BP神经网络算法、隐含层神经元个数、学习速率和动量系数进行优化,获得最佳的BP神经网络预测模型结构。基于Levenberg-Marquardt算法建立精确的L*、b*和△E预测模型,性能测试显示L*、b*和△E预测模型的相关系数(R2)分别为 0.847、0.825 和 0.924。相应的均方根误差(root mean square error,RMSE)分别为 4.609、3.564 和 5.012。基于拟牛顿BFGS算法建立精确的a*值预测模型,性能测试显示模型的R2和RMSE分别为0.905和2.237。
Abstract:Processed in a conventional manner smoked sausages as the research object,back-propagation(BP)neural network prediction model is used to predict the color of smoked sausage.Used the smoked sausage with different smoked temperature,smoked time and fineness ratio,the L*,a*,b*and△E value were determined,and the BP neural network algorithm,hidden layer neuron number,learning rate and momentum coefficient were optimized,and the best BP neural network prediction model structure.Based on Levenberg-Marquardt algorithm,the accurate L*,b*and△E prediction model are established.The performance test shows that the correlation coefficient(R2)of L*,b*and△E prediction model are 0.847,0.825 and 0.924,respectively.The corresponding root mean square error(RMSE)are 4.609,3.564 and 5.012,respectively.Based on the Quasi-Newton BFGS algorithm,an accurate a*prediction model is established,the performance test shows that the R2and RMSE of the model are 0.905 and 2.237,respectively.
