Effect of Swamp Eel (Monopterus albus) Plasma on The Quality of Tilapia (Oreochromis mossambicus) Surimi

The effects of crude plasma and ethanol-extracted swamp eel at different concentrations (0, 0.25, 0.5, 0.75, 1, 1.5, 2 mg/g) as inhibitor protease in the quality tilapia (Oreochromis mossambicus) surimi were investigated. parameters analyzed gel strength, expressible moisture, whiteness, microstructure, protein solubility, hydrolysis pattern by sodium dodecyl sulfate-polyacrylamide electrophoresis, percent inhibition, zymogram. results showed that could maintain inhibition lysis from activity caused formation modori structure better than plasma. whiteness decreased concentration used increased. SDS-PAGE for analysis effectiveness a There was an increase 1.5 mg/g. It suggested contained internal enzyme might interfere with reduced myosin intensity.
