Abstract The flavor characteristics of prepared lion’s head meatballs were evaluated by sensory evaluation and electronic nose, and analysis of variance, principal component analysis and grey correlation analysis were used to evaluate the correlation between sensory evaluation and electronic nose analysis. The results showed that braised lion’s head meatballs prepared in our laboratory scored the highest in sensory evaluation. There was good consistency between sensory evaluation and electronic nose analysis. The response of W1C sensor exhibited the highest correlation with flavor and overall sensory scores with correlation coefficients above 0.85. Spices and other auxiliary ingredients were the main factors causing the flavor difference of products.
