Oxidation of myofibrillar proteins and impaired functionality: underlying mechanisms of the carbonylation pathway.
Mariana Utrera,Mario Estévez +1 more
TL;DR: In this paper, the potential impact of protein oxidation on the functional properties of myofibrillar proteins (MP) was investigated in vitro for 12 days at 37 °C in the presence of Cu2+, Fe3+, and Mb in combination with H2O2 and analyzed at sampling times for chemical changes induced by oxidative reactions and functional properties.
Journal ArticleDOI
Protein oxidation during frozen storage and subsequent processing of different beef muscles.
TL;DR: A significant impact of frozen storage on protein oxidation was found, which occurred concomitantly with a loss of WHC, redness and significant changes in the hardness of cooked patties.
Journal ArticleDOI
Fat content has a significant impact on protein oxidation occurred during frozen storage of beef patties
TL;DR: This paper examined the relationship between protein and lipid oxidation and the impairment of water holding capacity (WHC), colour and texture after frozen storage (20 weeks/−18°C) and subsequent processing (cooking, chilled storage) of beef patties with increasing fat content (3, 20 and 35%).
Journal ArticleDOI
Formation of Lysine-Derived Oxidation Products and Loss of Tryptophan during Processing of Porcine Patties with Added Avocado Byproducts.
TL;DR: The combination of both strategies (back-fat replacement and addition of avocado extract) does not lead to an enhanced advantage on the oxidative stability of the product, and the antioxidant effect may respond to the protecting effect of phenolic compounds found on the avocado extract.
Journal ArticleDOI
Temperature of frozen storage affects the nature and consequences of protein oxidation in beef patties
TL;DR: Frozen storage increased the susceptibility of meat proteins to undergo further oxidation during processing, and timely interactions were found between lipid and protein oxidation.
