Protein hydrolysate contains a mixture of various lengths of short peptides chain and free amino acids that may&#x0D;excert biological activities. This research aims to screen potential antioxidant and antibacterial activities of protein hydrolysate&#x0D;produced from three kinds of germinated beans i.e. lablab bean (Lablab purpureus), pigeon pea (Cajanus cajan (L.) Millsp) and&#x0D;kidney bean (Phaseolus vulgaris) through enzymatic hydrolysis process. The steps of research included germination process of&#x0D;the beans prior to total protein isolation, enzymatic hydrolysis of total protein isolates using pancreatin enzyme, evaluation of&#x0D;in vitro antioxidant activity of the hydrolysates protein using DPPH (1,1-diphenyl-2-picryl hydrazyl) method, and antibaterial&#x0D;activity testing towards Eschericia coli and Staphyllococcus aureus bacteria. The results revealed that pancreatine enzyme was&#x0D;able to hydrolyse germinated protein of lablab bean, pigeon pea and kidney bean at the experiment condition applied with&#x0D;degree of hydrolysis 34.12%, 27.44%, and 30,93% respectively. It was also found that protein hydrolysates of lablab bean,&#x0D;pigeon pea, and kidney bean demonstrated antioxidant activity which percentage radical DPPH scavenging activity of 84.02%,&#x0D;68.97% and 67.89 %. On the other hand, all of those protein hydrolysates did not show any antibacterial activity towards&#x0D;Eschericia coli and Staphyllococcus aureus bacteria.

SCREENING POTENTIAL ANTIOXIDANT AND ANTIBACTERIAL ACTIVITIES OF PROTEIN HYDROLYSATES DERIVED FROM GERMINATED LABLAB BEAN, PIGEON PEA AND KIDNEY BEAN
