Article: Oxidation.(Executives: FYI ...)

Oxidation often leads to a decline in quality during the storage of ground beef. Adding such antioxidants as vitamin E can enhance meat quality and effectively stabilize red, oxymyoglobin color by delaying oxidation. Researchers wanted to determine the effects of vitamin E on the heat stability of myoglobin (Mb) in ground beef. The thermal denaturation of Mb began at 40 C for samples heated at 0.8 C per min. The point of denaturation when heating the product at 1.4 C per min was not as clearly defined. When heated at 0.8 C per min, samples containing vitamin E had a significantly lower ...
