摘　　要：以山西土著库德毕赤氏酵母(Pichia kudriavzevii)Y1作为发酵菌株制备山楂酒,以总黄酮含量及酒精度为评价指标,采用单因素及响应面试验优化山楂酒发酵工艺。结果表明,最佳发酵工艺条件为发酵温度31℃,接种量13%,初始糖度25°Bx,发酵时间10 d。在此最佳条件下,山楂果酒酒精度为(11.07±0.09)%vol,总黄酮含量为(16.10±0.15)mg/mL,感官评分为38分。山楂酒酒体透亮,果香与酒香协调馥郁,口感柔和,风味独特。Using Shanxi native Pichia kudriavzevii Y1 as fermentation strain,a hawthorn wine was prepared,and the fermentation process was optimized by single factor and response surface tests with total flavonoids content and alcohol content as evaluation indexes.The results showed that the optimal fermentation conditions were fermentation temperature 31℃,inoculum 13%,initial sugar content 25°Bx and fermentation time 10 d.Under the optimal conditions,the alcohol content of the hawthorn wine was(11.07±0.09)%vol,the total flavonoid content was(16.10±0.15)mg/ml,and sensory score was 38.The hawthorn wine had bright body,harmonious aroma of fruit and wine,soft taste,unique flavor.
