Abstract: sIgA is a primary immunoglobulin mediating mucosa immunity.Some physics and chemistry characteristics enable sIgA to lead mucosa immunity.Synthesis and secretion of sIgA in milk is accessorial production of mucosa immunity,which comes into being in evolution for offer passiveness immunity of mucosa for offspring.This article summarize function and synthesis mechanism of sIgA in milk.Some techniques to increase the content of sIgA in milk are introduced.Thus some references were offered for production of immune milk with high-titer sIgA in future.

Key words: milk; sIgA; mucosa immunity; immune milk
