Abstract: Based on central composite design response surface methodology was applied to optimize fermentation parameters for pumpkin wine. Alcohol content in pumpkin wine was investigated with respect to yeast inoculum size, temperature and fermentation time, and a quadratic polynomial model was established. The optimum fermentation parameters were determined as follows: yeast inoculum size 0.10%, fermentation temperature 24.58 ℃ and fermentation time 129.73 h. The alcohol content in the pumpkin wine obtained was 8.03% (V/V).
