Abstract: For the purpose of producing humanized protein raw material for infant formula,trypsin was used for hydrolyze and the change of particle size in skim milk protein and clot caused in the simulated environment of infant stomach during hydrolysis were studied,and compared with breast milk.Laser particle analyzer and scanning electron microscopy were adopted to compare macro and micro change during hydrolysis in simulated environment of infant stomach,and also molecular weight distribution of hydrolyze was analyzed.The results showed that the optimal condition for trypsin hydrolysis was 45 ℃,e/s 0.5% and hydrolysis 1h.Under this hydrolysis conditions,the clot of milk protein hydrolysates formed in simulated gastric environment was closest to breast milk on macro and micro structure.So humanized protein raw material could be produced by trypsin hydrolysis.
