Synergistic recovery and enhancement of gelling properties of oxidatively damaged myofibrillar protein by l-lysine and transglutaminase

•Lysine (Lys) and transglutaminase (TG) are combined to treat oxidatively damaged myofibrillar protein (MP).•The TG addition improves breaking strength of oxidized MP gels while reduces the cooking yield.•The presence of Lys significantly improves the gelling properties and cooking yield of oxidized MP gels.•The Lys + TG treatment shows the best overall improvement of oxidatively damaged MP gelling capacity.
