Kinetics analysis of the reactions responsible for myoglobin chemical state in meat using an advanced reaction–diffusion model

Effect of light treatmeat on oxidation and flavour of dry-cured Wuchang fish

“…Myoglobin (Mb) has photosensitivity, and it falls into different derivative types including oxymyoglobin (MbO 2 ) and Metmyoglobin (MetMb), which can be transformed into each other. Oxymyoglobin can change the valence state of iron ions under lighting conditions ( Kondjoyan, Sicard, & Badaroux, 2022 ). The effect of lighting conditions on Mb was shown in Fig.…”

Predicting the Oxidative Degradation of Raw Beef Meat during Cold Storage Using Numerical Simulations and Sensors—Prospects for Meat and Fish Foods

“…The second approach based on the myoglobin oxidation model of Kondjoyan et al [36] was more fundamental, while still making the following assumptions: the meat was modeled as a unidimensional single muscle compartment; the reaction rate constants, available at 20 • C, were adapted at the storage temperatures using a single activation energy value; the fraction of MbFe 4+ was also neglected in comparison to the fractions of the other forms of myoglobin. Those assumptions established model limitations.…”

“…Note that a list of symbols is provided in Appendix A, Table A1, and that detailed presentations of the phenomenological model and of the reaction-diffusion model used in this paper are available in the literature [36,42].…”

“…In the previous study [36], the calculations of the myoglobin profiles were performed at a temperature of 20 • C. Here, myoglobin concentrations needed to be calculated at the surface at 2 • C, 6 • C, and 10 • C to compare the computations against the previous measurements of a*. Thus, the system of equations was completed with an Arrhenius relation to determine the effect of temperature on the rate constants (Equation ( 6)).…”

“…Tofteskov et al [35] developed a more comprehensive numerical model to predict meat preservation under modified-atmosphere packaging (MAP). Kondjoyan et al [36] developed the most comprehensive model of myoglobin chemical state to date, which considered the kinetics of 22 impactful reactions.…”
