This study aims to investigate the effect of high-pressure processing on the quality of black tiger shrimp using response surface methodology. A central composite rotatable design was applied to evaluate the effects of three processing parameters, namely pressure (300–600 MPa), temperature (30–50 ℃), and time (0–15 min), on the inactivation rate of Staphylococcus aureus and physical properties (color and texture) of shrimp and to optimize the process conditions to achieve maximum bacterial inactivation with minimal changes in quality attributes. The results revealed that the processing conditions significantly affected the studied responses and the experimental data have been adequately fitted into a second-order polynomial model with multiple regression coefficients (R2) of 0.92, 0.92, and 0.94 for the inactivation rate of S. aureus, hardness, and color changes, respectively. The optimized conditions targeting minimum six log cycle reductions of S. aureus with moderate changes in quality attributes were obtained as: pressure, 361 MPa; time, 12 min and temperature, 46 ℃. The adequacy of the model equation for predicting the optimum response values was verified effectively by the validation data.
