Abstract: The synergistic effect of cortex mouton (CM) extract, a quorum sensing inhibitor, combined with tea polyphenols (TPs) on the quality of turbot fillets during cold storage were investigated in this paper. The results showed that the combined treatment of CM extract and TPs could slow down sensory quality deterioration of turbot fillets and significantly decrease total viable count, pH, total volatile basic nitrogen (TVB-N) content, thiobarbituric acid (TBA) content and K-value as a freshness indicator compared with individual treatments and the control (P < 0.05). In addition, the combined treatment extended the shelf life by about 9, 6–7 and 2–3 days compared with the control and individual CM extract and TPs, respectively while having no significant effect on the color. Therefore, the combined treatment of CM extract and TPs could synergistically act to effectively slow down the deterioration of refrigerated turbot, and maintain the quality of fish muscle.
