WebLastly, lipid oxidation was determined by finding the concentration of malondialdehyde per kg of meat tissue. Data were analyzed using SAS Proc GLIMMIX with a split plot design and an α of 0.05 was considered significant. Myoglobin was denatured 29.08%, 48.34% or 70.17% at each DOD, respectively. WebMyoglobin and lipid oxidation are major causes of quality deterioration in fresh ground beef during storage. Honey is a complex natural liquid reported to contain a variety of antioxidants such as catalase, ascorbic acid, flavonoids and alkaloids.

Webmyoglobin oxidation that occurs at low oxygen concentrations (George and Stratmann, 1952; Sørheim, Grini, Nissen, Andersen & Lea, 1995), which occurs at the limit of oxygen diffusion into meat in PVC packaging and is visible as a brown sub-surface band (Cornforth, 1994). To prevent browning, meat package oxygen levels must be less than 0.15%. WebAs meat is stored, the relative proportions of the three chemical states of myoglobin continue to change. When fresh beef is ground, the degree to which the beef blooms (turns bright red, formation of OMb) is influenced by the respiration of the muscle, its reducing activity (ability to keep the iron in the reduced state) and the pH of the meat. root and branch physical therapy
