Abstract: The article presents the results of a study on optimizing the process of maturation of muscle tissue of mirror carp (Cyprinus Carpio) and silver carp (Hypophthalmichthys Nobilis) grown in the Kaliningrad region using two types of maturation intensifiers: a complex pH-regulating additive (RUTAFISH Mirsol BS) and an enzyme preparation (EC 60,000+K). It was found that the natural proteolytic activity in both species (pH 6.49–6.55 units) is insufficient for effective hydrolysis of muscle tissue, which justified the need for the use of maturation intensifiers. To model and optimize the maturation process of carp and silver carp muscle tissue with maturation intensifiers, a second-order orthogonal central compositional plan (OCCP) was used, in which the duration of hydrolysis (h) and the mass fraction of the maturation intensifier (%) were variable factors. As a result of the experiments, second-order regression equations describing the dependence of the maturation efficiency indicator on these factors were obtained. The adequacy of the models was confirmed by the Fisher criterion with a confidence probability of 0.95 and a coefficient of determination R2 exceeding 0.9. Mathematical processing of the models allowed to calculate the optimal values of the factors ensuring the achievement of the maximum functional and technological effect under the specified conditions. When using RUTAFISH Mirsol BS, the factor values were 18.0 hours and 1.27% for carp mirro muscle tissue, 17.9 hours and 1.24% for silver carp; while when using EC 60,000+K, they were 25.0 hours and 2.93% (mirror carp), 21.2 hours and 4.94% (silver carp). These values of the mass fraction of the enzyme preparation exceed the maximum permissible level of introduction into the product (2.5%), which limits its practical use. Thus, RUTAFISH Mirsol BS is the preferred intensifier that ensures effective maturation within the framework of regulatory requirements. The data obtained can be used in the development of technologies for deep processing of aquaculture raw materials, including fish species with a low ability to mature naturally.
