Effect of Whey Protein Isolate-Meniran Extract (Phyllantus niruri L.,) Eencapsulation Using Casein Hydrolysate on Foam, Optical Microscopy, Particle Size, and Viscosity

The purpose of this study was to determine the effect whey protein isolate (WPI)-extract meniran (Phyllanthus niruri L.) encapsulation using casein hydrolyzate on foam overrun, optical microscopy, particle size and viscosity. materials used isolate, an extract encapsulated hydrolyzate. method a completely randomized design (CRD) with 5 treatments hydrolyzed as material, 0%, 2%, 4%, 6% 8%, namely P0, P1, P2, P3 P4 repectively, 3 replications. variables observed were size, viscosity which analyzed analysis variances (ANOVA). If there is significant or very difference, will be continued DMRT (Duncan Multiple Range Test). Variable microscopy descriptively. results showed that isolate-meniran gave difference (P<0.01) in overrun but did not give (P>0.05) size. average value 325% - 400%, 0.985 cP 1.015 cP, 0.8944 nm 1.5031 nm, most abundant distribution amount P4, 8% Along addition different concentrations (2%, 6%, 8%), shape became more even uniform. conclusion able maintain physical properties WPI-meniran viscosity, optimal shape, uniform lamella tend thick.
