Effects of high static pressure on digestibility of bovine colostrum casein in simulated gastric fluid

The bovine colostrum as raw material was treated with high static pressure and the improvement function to digestibility of casein in simulated gastric fluid was researched in this study. Casein in bovine colostrum was digested in simulated gastric fluid after being treated with high static pressure at different condition ( pressure, temperature and holding time) , and the content of casein and its digest was detected using capillary electrophoresis.The results showed that, in the experiment condition range, the casein in bovine colostrum was well digested after being treated under 550MPa pressure for 25min at 40℃.So the high static pressure processing bovine colostrum can improve digestibility of casein in simulated gastric fluid.
