摘  要:以牛奶为主要原料,添加红甜菜汁等辅料,以保加利亚乳杆菌和嗜热链球菌为发酵剂,以白砂糖为调味剂,通过单因素试验及k(34)正交试验确定出最佳工艺流程及工艺参数为:牛奶(100mL)和白糖(8p→灭菌(12℃,5s)→接A.5%的发酵剂→42℃恒温发酵(5h)→加入4%的红甜菜汁→后发酵(0℃~5℃,24h)。此产品不仅保留了酸奶风味清新、酸甜可口的特点,在0℃~5℃时的货架期为20d左右。Milk was used as the main ingredient, the red beet juice as the supplementary materials, the Lactobacillus bulgarian and Streptococcus ther- mophilus as the hametz, and the white granulated sugar as the flavoring agent to produce new type red beet yoghurt. And its process flow and techno- logical parameter were optimized by L9 (34) orthogonal tests and single factor experiments. The specific materials and process flow are as follows: Milk (100 ml) and white sugar (8 g) → antiseptic (121℃, 5 s) → add 5% hametz → 42℃ fermentation under constant temperature (5 h) → add 4 % red beet juice→ after fermentation (0~5℃, 24 h). This product retains the yogurt's flavor characteristics of being sour and sweet. Adding the red beet juice makes the yoghurt having a delicate fragrance. This new-type red beet yoghurt contains lots of nutrient substance, which helps strengthen the human body immunity. Therefore, it is a type of multifunction yoghurt and its shelf life is 20 d when the temperature ranges from 0℃ to 5℃.
