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.

The response surface methodology (RSM) and central composite design (CCD) technique were used to optimize the three key process parameters (i.e., pressure, temperature and holding time) of the high-hydrostatic-pressure (HHP) processing either standalone or combined with moderate thermal processing to modulate molecular structures of β-lactoglobulin (β-Lg) and α-lactalbumin (α-La) with reduced human IgE-reactivity. The RSM model derived for HHP-induced molecular changes of β-Lg determined immunochemically showed that temperature (temp), pressure (p2) and the interaction between temperature and time (t) had statistically significant effects (p < 0.05). The optimal condition defined as minimum (β-Lg specific) IgG-binding derived from the model was 505 MPa at 56 °C with a holding time of 102 min (R2 of 0.81 and p-value of 0.01). The validation carried at the optimal condition and its surrounding region showed that the model to be underestimating the β-Lg structure modification. The molecular change of β-Lg was directly correlated with HHP-induced dimerization in this study, which followed a quadratic equation. The β-Lg dimers also resulted in the undetectable human IgE-binding.
