Abstract: Chitosan, nisin and lysozyme were used to develop an antibacterial formula for braised whole chicken. In order to find the optimal formula, response surface methodology was employed to optimize antibacterial rate as a function of the levels of added ingredients based on a regression model. The best antibacterial effect was observed when 0.36% chitosan, 0.038% nisin and 0.05% lysozyme were added to braised whole chicken, resulting in an antibacterial rate of 95.4% after 3 d of storage at room temperature. Moreover, the experimental data could be well fitted with the established regression model.
