However, this method is associated with food quality issues, including long fermentation periods, inconsistent quality, and high nitrite (NIT) levels.

The response surface method was employed to optimize the concentration of the protective agent and evaluate its storage stability. Fresh mustard was inoculated with the fermentation agent, and the quality parameters of the mustard during fermentation were comprehensively analyzed. The findings showed that the optimal concentration (g/100 mL) of the lyophilized protective agents, determined by response surface analysis, was 12.50 trehalose, 5.50 mannitol, and 12.00 skimmed milk.
