This article presents research results from the freeze drying regime for penaeus monodon based-on the solution of the multi-objective optimization problem. Experiments were carried out to determine the objective functions to describe influence of technological parametres (temperature and pressure of sublimation environment, times of freeze drying) during processing freeze drying. The multi-objective optimization problem was solved by Utopian point method with combination criteria s. The best technological regime for freeze drying was determined. At received freeze drying regime we have minimal energy expenditures, minimal contraction of product and minimal loss of vitamin c, humidity of material meet requirements from 2 to 6 percentage and maximal absorbent return of product.
