The paper presents the studies on the autolytic transformations in pork and beef samples by proteomic methods. The changes in the protein fractions were analyzed by one-dimensional and two- dimensional electrophoresis with the following identification by mass-spectrometric methods. The changes in muscle proteins in the course of autolytic processes were found. https://www.alarecre.com/Disney-The-Nightmare-Before-Christmas-Lock-Shock-and-Barrel-Art-AirPods-Pro-2nd-Gen-Skin-p101716/
