In this study we investigated the influence of rice wine (Jinbiao, Yinbiao, Wunianchen, Nv’erhong) on the activity of endogenous proteases, myofibrillar degradation and quality characteristics in topmouth culter muscle. Rice wines had pH of about 4.3, and micromolar level of calcium ions. Nv’erhong (NEH) had the highest total phenolics content, while Wunianchen (WNC) showed the strongest total antioxidant capacity. WNC showed the considerable inhibitory action on the endogenous proteases, and delayed the degradation of myosin heavy chain and α-actinin, which occurred more quickly in other groups, especially in blank and alcohol controls. Total volatile base nitrogen production and texture profile for the fish fillets confirmed the improvement role of rice wine on the quality. In general, rice wine can inhibit the endogenous proteases and reduce the extent of myofibrillar degradation on the combined role of acidic pH and antioxidative components, resulting in the maintaining of good quality of the fish.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
