摘要:本文以牦牛乳、雪梨浓缩汁、沙棘汁为主要原料制备沙棘雪梨牦牛酸奶,探究果酱添加量、均质压力、发酵终点酸度三个参数对牦牛酸奶产品感官品质的影响。在发酵温度为44 ℃,乳清浓缩蛋白粉添加量为3.00 g/100 g,变性淀粉添加量为1.00 g/100 g,白砂糖的添加量为8.00 g/100 g,菌种0.05‰条件下优化产品配方及工艺,通过响应面分析得到最佳参数为:果酱添加量为4.00 g/100 g,均质压力为25 MPa,发酵终点酸度为83°T

AbstractThis essay used yak milk, snow pear juice concentrates and seabuckthorn juice as main raw materials to process yak milk yogurt, exploring effect of jam addition, homogeneous pressure and fermentation end-point acidity on the sensory quality of yak milk yogurt. When the fermentation temperature was 44 ℃, the addition of whey protein concentrate was 3.00 g/100 g, the modified starch 1.00g/100g, the white granulated sugar 8.00 g/100 g and 0.05‰ strain, the product formula and process were optimized. Through response surface analysis, the optimal parameters are obtained as follows: jam dosage 4.00 g/100 g, homogenization pressure 25 MPa, fermentation end point acidity 83°T.
