摘要: The study analysed mechanically deboned chicken meat subjected to washing and separation of fat connective tissue in order produce a preparation myofibrillar proteins (MP). was modified using microbial transglutaminase (MTG). For this purpose, MP supplemented with 3 g/kg MTG at 6–7 °C for 5 h. Changes the dynamics water binding, which occurred course heating cooling within temperature range 20–70–20 °C, were tested systems. Relaxation times T1 T2 determined low-field nuclear magnetic resonance (NMR). Enzymatic modification resulted significant changes bulk binding protein Due presence preparation, begin end lower temperatures. Analysis relaxation time showed that addition enzyme causes sample up 48 h after gel cooling. reduces energy barrier determined, based on activation energy.
