摘要
通过研究不同发酵工艺、发酵剂及发酵条件对紫薯风味酸乳感官评价及花青素含量的影响,确定最佳工艺条件:以8种菌复合发酵剂进行发酵,发酵前紫薯粉添加量4.0%,白砂糖添加量8%,发酵温度43℃,发酵时间6.5 h。在此条件下制得的紫薯风味酸乳色泽均一,紫薯风味明显且花青素含量较高。
Purple potato has rich nutritional value. Through leaven screened,optimized the ratio of materials and fermentation conditions. The optimal technology is determined by sensory evaluation and contents of anthocyanin: using the mix leaven,adding 4.0% the purple tomato starch before fermentation,sugar 8%,fermentation temperature 43 ℃,fermentation time 6.5 h.The product has a unique flavor of purple potato and higher anthocyanin content.
