The application of natural vitamin E purification in molecular distillation based on GA-BP

BP gets local minimization too easily and converges slowly and could not get the global optima. To solve these problems, this paper proposes GA-BP algorithm to predict the purity of vitamin E in obtaining the purity of vitamin E with molecular distillation. The genetic algorithm is applied to optimize the weights of BP neural network and the combination of the advantages of two arithmetic improves the response time efficiently and forecast precision. The simulation results show that this algorithm can get an ideal result on the both, so which has a high application value.
