Biological activities of released peptides from pancreatic hydrolysis of bovine casein depend on the molecular weight.Peptides with different molecular weights have different functions.In this paper

typical neural network was applied to simulate molecular weight distribution and get 3D plot of released peptides from pancreatic hydrolysis of casein.During the simulation

when hidden layer was 2 and hidden nodes were 30

R2 was 0.9922.The result was good when back propagation (BP) artificial neural network (ANN) was used to predict molecular weight distribution of released peptides.The prediction result was further used to get 3D plot of molecular weight distribution of casein pancreatic hydrolysates.The best degree of hydrolysis could be chosen by this 3D plot

when the peptides with given molecular weights were required.
