Abstract: When more and more new kinds of bioactive peptides were discovered, the studying area for bioactive peptides became a focus of attention in many countries. Many research works have shown that a large number of bioactive peptides could be found when some kinds of rich proteins could be hydrolyzed by proper proteinase. These peptides not only had various biological functions and sequence diversity but they were also easy to get with abundant resoucces , lower cost and safely, conveniently to scale up, so it has attracted many scientists attentions. As a good example, casein has been of rich protein in mammal milk. For a long time, milk proteins particularly casein, have been considered as only food proteins for young mammals. Casein was also the principal source of amino acid for young animals. But besides the nutritional role, casein had also a physiological importance,i.e., it was the important source of bioactive peptides. Many kinds of bioactive peptides have been discovered from hydrolyzed casein. So it would be very important and of good prospects to do more research works on this area.
