WebbThe first protease that catalyses the hydrolysis of these intact proteins is pepsin, which is secreted in the stomach. Pepsin is active at pH ranging from 1 to 6, with a maximum activity between 1.5 to 2.5. 1 However, this optimum depends on the type and denaturation state of the substrate. 2,3 Meanwhile, trypsin, chymotrypsin and elastase are secreted … Webbacid caused a slower reaction of protein termination resulting in an increase in the casein yield. The casein yield value decreased at 60 minutes due to the protein matrix termination reaction so that more water came out. However, casein yield value re-increased at 90 minutes due to the re-absorption of water content in the protein matrix.
