Abstract
This study aimed to investigate the protective effects of l-arginine (L-arg) and l-lysine (L-lys) on the structure and gel properties of myofibrillar protein (MP) in duck meat during several freeze-thaw (F-T) cycles. The analysis of the Ca2+-ATPase activity as well as total sulfhydryl and carbonyl contents demonstrated that L-arg and L-lys could slow down the oxidative denaturation of MP during F-T cycles. Circular dichroism, fluorescence spectroscopy, and rheology measurements indicated that L-arg and L-lys improved the stability of the secondary and tertiary structure of MP and preserved its gel properties. In summary, L-arg and L-lys had the potential to preserve the structural stability and gel properties of MP during F-T cycles.
