Abstract

Centrifugal force and time for the primary clarification of hepatopancreatic homogenate of red shrimp was determined on the optimum recovery of alkaline phospatase. Centrifugal force of 1681.1×g for 5 min or more than 1681.1×g for 5, 10, 15, or 20 min successfully clarify 96.99±0.45% of the total solids, 93.16±1.03% of soluble protein, and 93.61±0.16% of the lipids from the respective initial homogenate. However, the centrifugal force more than 1681.1×g caused denaturation of alkaline phosphatase due to hydrodynamic sheer even at the temperature of 4oC. Centrifugal force of 1681.1×g for 5 min was able to retain 94.29±1.44% of the alkaline phosphatase of the initial homogenate, eventhough clarified 89.98±0.01% of the total solids, 77.25±0.89% of soluble protein, and 78.76±0.64% of the lipids from the respective initial homogenate. Centrifugal force of 1681.1×g for 5 min is an efficiently removes insoluble while retaining optimum alkaline phosphatase activity.
