摘要：The results of the effects of transglutaminase (TG) and bacterial concentrates (BC) of different strains of microorganisms on the functional and technological properties of minced meat obtained from beef trimming (80/20) are presented. A control and seven experimental samples of minced meat were obtained ļ three samples with the addition of 10% BC: Bi lact-Pro, Bi lact-AD, Bi lact-Ke r (S-Pro, S-AD, SK), a sample with the addition of 0.2% TG (S-TG) and three samples with simultaneous addition of 5% BC: Bi lact-Pro, Bi lact-AD, Bi lact-Ke r and 0.1% TG (S-Pro + TG, S-AD + TG, S-K + TG). The control and experimental samples were analyzed for: pH, water binding capacity (WBC), water holding capacity (WHC), cooking loss, as well as physicochemical and rheological properties. The highest WHC was observed in the S-TG samples during the ļ12 h of ripening, whereas in the S-Pro+TG, S-AD+TG and S-K+TG samples during the ripening period of 12ļ18 h. The data obtained correlated with an increase in the pH value in the samples during the indicated periods. Signi cant differences were noted in the changes in WBC and WHC when BCs were added to the minced meat, as dependent on the composition of the microorganism cultures. The lowest cooking losses were determined in the S-TG sample, i.e. 19.03ļ19.99% (p<0.05), whereas in the S-AD+TG and S-K+TG samples they reached 17.91ļ18.61% (p<0.05) and 18.96ļ19.58% (p<0.05), respectively. The most pronounced elastic properties were found in the samples with TG. Thus, the results showed that the combination of BC and TG demonstrates a synergistic effect on the functional and technological properties of meat systems.
