在新加坡如何在家制作酸奶？
如今新加坡的超市里有大量乳制品和酸奶产品。你可以看到从原味到带水果口味和配料（如果酱、坚果等）的多种酸奶。酸奶对人体健康有益，其简单的配方使其易于自制。因此，喜欢吃酸奶的人会选择在家自制酸奶。
自制酸奶制作步骤
- 一般需要准备两袋牛奶和1杯酸奶，然后以10:1的比例混合牛奶和酸奶。接着用沸水对酸奶机中的塑料容器进行1分钟灭菌，然后倒掉水，再把事先准备好的两袋牛奶倒入其中。
- 然后倒入酸奶，用筷子或其他工具搅拌均匀。将装有的容器放入酸奶机中，然后盖上酸奶机的盖。接通电源，酸奶机开始工作。酸奶发酵过程大约需要8小时。若在冬季制作，发酵时间再增加约2小时。
- 制作完酸奶后，取出塑料容器，可以看到酸奶浓稠如豆腐脑，然后放入冰箱冷藏2至4小时再食用。
提示： 最好把准备好的酸奶直接放入冰箱，这样可以防止酸奶再次发酵。制作酸奶前用的发酵菌源可用一杯超市购买的酸奶作为发酵菌源，或可用双歧杆菌作为菌源。配比：1克双歧杆菌粉 1000毫升牛奶。饮用酸奶时，可根据口味添加糖、水果或其他饮料。
