General Stability

General Stability Organism
analysis of the stability of fruit bromelain in fruit pulp within a high-pressure domain of 0.1-600 MPa/30-70°C/1 s-30 min. The pulse effect is quantified as a function of pressure, temperature, pressure build-up and decompression times. A maximum of 60% reduction in FBM activity is obtained after a single pulse of 600 MPa/70°C. Upon applying nth order model, the obtained reaction order (n) for thermal (0.1 MPa/30-70°C) and high-pressure (100-600 MPa/30-70°C) inactivation is 1.1 and 1.2, respectively, inactivation rate constant, isothermal inactivation at atmospheric pressure, detailed overview. The activation energy is nonlinearly dependent on pressure, whereas the activation volume is linearly related to temperature. The empirical model appears to be more realistic than those from the log-linear kinetics. At 600 MPa/70°C, the first-order kinetics predict that 90% of initial FBM activity will be reduced after 46 min of pressure hold period, whereas, the empirical model predicts a dwell time of only 26 min for the same.
