%0 Journal Article %T Kinetics of Hydrolyzing Isolated Soy Protein by an Endopeptidase and its Conceptual Application in Process Engineering %A Zebin Wang %A Jason Lombardi %A Jessica Shaffer %A Ted Wong %J International Journal of Food Studies %D 2012 %I ISEKI_Food Association (IFA) %X A response study and the effects of different parameters (pH, temperature and enzyme dose) on kinetics of isolated soy protein hydrolysis by a trypsin-like endopeptidase (TL1) were conducted. Degree of hydrolysis (%DH) data varied at different times under different hydrolysis conditions. Fitting the kinetics data to Michaelis-Menten kinetics model did not result in reasonable kinetic parameters, which implied that Michaelis-Menten kinetics was invalid for such a hydrolysis process. A kinetics model proposed by (Gonzalez-Tello, Camacho, Jurado, Paez, & Guadix, 1994) was found to fit the kinetics curve well and resulted in acceptable model parameters. A simple simulation example was performed to demonstrate the concept of how the kinetics equation could be applied in process engineering. %K isolate soy protei %K protein hydrolysis %K hydrolysis kinetics %K Trypsin-like endopeotidas %K process simulation %U http://www.iseki-food-ejournal.com/ojs/index.php/e-journal/article/view/31
