Optimization of free radical scavenging activity by response surface methodology in the hydrolysis of shrimp processing discards
Abstract : Response surface methodology (RSM) was used to optimize the hydrolysis conditions (temperature, pH and Alcalase® 2,4L concentration), in order to obtain the hydrolysate with the strongest antioxidant activity using the 1,1-diphenyl-2-picryl-hydrazyl (DPPHradical dot) decolouration assay. The optimum conditions obtained from experiments were pH 9.7, 66.2 °C, enzyme concentration = 68.1 Anson units (AU)/kg crude protein. The analysis of variance in RSM showed that pH and temperature (T) were the most important factors of the process (P < 0.001). The experimental conditions produced both an enzymatic and chemical protein solubilization.
