Abstract—The establishment of the technological mode of the freeze drying process of Penaeus monodon was based on the solution to a multi-objective optimization problem. Experiments were carried out to set up the objective functions describing the influence of technological factors (temperature and pressure of freeze drying chamber, and time of freeze drying) to the freeze drying process. The restricted area method was applied to solve the multi-objective optimization problem, determining the optimal technological mode of freeze drying process (correspondingly 31.000C, 0.008mmHg, and 13.82h) in order that the objective functions reached the minimum value in terms of the final product, including the energy consumption of 5.84 kWh/kg, the residual water content of 4.67%, the anti-rehydration capacity of 6.98%, the volume contraction of 8.49% and the loss of total protein of Penaeus monodon after freeze drying of 2.95%.
