Abstract The neutrase was chosen as the best protease from five different protease in the test of enzymatic hydrolysis of sheep bones because the result showed that DH% and TCA-NSI% were the highest when using neutrase.Neutrase was used to hydrolyzes heepb onesf orf urthers tudya ccording to five factors quadratic orthogonal design with DH% as only guide.The optional hydrolysis param-eters of neutrase were given as:temperature 50. 5℃;enzyme concentration230U/g raw material; reactant concentration 47kg/L;pH7.0;time 6. 2h.At the same time,the result was found in the test that temperature、enzyme concentrationa nd reactant concentration have great influence on hydrolysis,but pH and time have no.
