分享一个自制酸奶的小窍门 写和人有关的帖子,左派和右派总有人不高兴。这次写一个和东西有关的帖子。该是不会又有问题吧。这是一个我自己摸索的办法。有最大一个优点,就因为不用火煮,牛奶的残迹不容易结在容器器皿上,洗刷器皿省掉了不少的力气。这样恐怕牛奶蛋白质的损失,也会减少到最低限度。
制作过程如下:Home-made Yogurt 材料: 半加仑任何种类的牛奶。 一盒“丹农”纯天然脱脂原味酸奶,参考图片。 蔗糖100-200克。 链接:http://en.wikipedia.org/wiki/酸奶 。
具体程序: 将混合牛奶放入玻璃器皿容器中。 半加仑牛奶中加入100~200克蔗糖,搅拌均匀。 微波加热10~20分钟,或直到温度达到或超过80℃,确保蔗糖完全溶解。 加热的牛奶在室温下冷却约2小时,直到温度降低到45℃以下。 【选择项牛奶浮皮可以丢弃,但不是绝对必要。】 将1盒丹农OIKOS/纯天然脱脂酸奶【或2盒加速酸奶成熟】加入牛奶中,彻底混合均匀。 容器用容器盖或简单地用塑料薄膜覆盖,以防止杂菌微生物落入。 为获得最佳效果,可以在最初的2小时内,考虑每小时搅拌一次混合牛奶的选项。然后,在室温下静置过夜。环境温度最好在30~43℃之间,或温度较低时静置稍延长时间。 酸奶制成完毕后,可以分装储存在冰箱或冷冻机(也可以被用作种子,储存时间不太长的话,可以再次接种的目的)。 》刚刚成熟的酸奶,汤匙可以立在里面不倒 图二:超市可买到的,用于接种目的的酸奶
英文: Materials: Half or a full gallon of milk of any kind. Single serve Dannon “All Natural Nonfat Yogurt, Plain, referred to the pictures Sugar http://en.wikipedia.org/wiki/Yogurt Procedure: Add 100~200g sugar to the milk and mixed well. Microwave the mixed milk in a glassware container for 10~20 minutes, or until the temperature reaches ~80℃ or a little more. Be sure the sugar is completely dissolved. Let the milk cool for ~2 hours at room temperature to below ~45℃. Option: milk skin can be discarded but it is not absolutely necessary. Seed the Yogurt [Good with 1 can DANNON OIKOS/All Natural Nonfat Yogurt, Plain, for a half gallon milk, or 2 cans for a quick maturation] into the milk and mix it gently and thoroughly. The container is covered with either container cover or simply with plastic film to prevent irrelevant microbe dropping. For best result, stir the mixed milk once an hour for the first 2 hours, and then let it stand at room temperature for overnight [ambient temperature best between 30~43 ℃], or a little longer time while the temperature is low. When ready, it can be stored in a refrigerator or freezer for longer period of time (it might also be used as a seed for approximately another 2 runs if it is not stored for a longer period of time).
