Objective: In this study, we aimed to analyze changes in the physical and sensory properties of Dezhou braised chicken brine during its repeated use for the purpose of providing a theoretical basis for standardized production of Dezhou braised chicken. Methods: Turbiscan stability index (TSI), transparency, particle size, turbidity, viscosity and color parameters of fresh and used braised chicken brine were measured. Results: TSI, transparency, particle size and L* value firstly declined and then tended to be stable, and turbidity, viscosity, a* and b* values increased until reaching a plateau with repeated use of the braised brine. The overall evaluation showed that TSI, transparency, particle size, turbidity, viscosity, and L*, a* and b* values of the brine were 0.5, 0.35%, 25.46 μm, 1 089 NTU, 0.42 × 10-2 Pa·s, 22.63, 0.61 and 6.48, respectively. Furthermore, TSI, transparency, color parameters, particle size and turbidity had significant correlations with each other. Conclusion: The braised chicken brine gradually became a complex and stable multicomponent system during repeated use, achieving the best particle size, turbidity and color parameters, and it was suitable for braised chicken processing and quality standardization.
