摘要
该研究以保加利亚乳杆菌(N14)和嗜热链球菌(L16)为基础发酵菌,分别添加干酪乳杆菌(GL2)、副干酪乳杆菌(GL6)、酵母菌(Y18)、开菲尔乳杆菌(700)构成了五种酸奶发酵剂组合,分别测定这五组酸奶的酸度、质构及感官特征,采用高效液相色谱(HPLC)法对酸奶中的苹果酸、乙酸、柠檬酸、乳酸进行定量分析,评价添加不同菌株对酸奶口感和风味的影响。结果表明,4种菌株添加均提高了酸奶的酸度,且酸奶酸度变化趋势与第一循环硬度、弹性、胶着性相同;添加菌株GL2、700和GL6提高了酸奶中乳酸的含量;添加菌株GL2的酸奶感官评分最高(92.55分),在果香、蒸煮味、纸板味方面表现突出,但添加菌株GL6的酸奶的感官特征与市售酸奶最为接近。
