A 7-level uniform design involving white sugar amount and xylitol-to-syrup mass ratio was used to optimize on the overall sensory score of chewing gum. Meanwhile, the effect of white sugar amount on textureproperties of chewing gum was evaluated, and a correlation analysis was performed between the two parameters and textureproperties of chewing gum. The results showed that the optimal chewing gum formula (based on flour mass) was 8% butter, 24%white sugar, and auxiliary ingredients (based on gluten mass) including 0.1% xanthan gum, 10% xylitol and 80%modified starch. The optimizations provided better sensory quality of chewing gum.
