馒头是人们的主食之一。现在市面上能买到的馒头都是用发面做成的。什么是发面呢?就是利用酵母菌,使面团里充满气泡并膨胀,这样蒸好后的馒头好吃柔软。老人们喜欢用老面头做发面的引子,而现在发面多是用活性干酵母了。老面头和干酵母,在发面的过程中有什么区别呢?哪种发面的方法更好?我和爸爸决定做一次发馒头的实验,让小酵母和老面头比比看谁更厉害。 Steamed bread is one of the staple foods of people. Now available on the market are made of buns made with noodles. What is baking it? Is the use of yeast, so that the dough is full of bubbles and expansion, so steamed good steamed bread delicious. Elderly people like to use the old noodles to make the face of the priming, and now made more active dry yeast. What is the difference between the old noodles and the dried noodles in the process of making noodles? Which kind of noodles are better? My father and I decided to make a trial of making the bread so that the little yogurt could compare to the old ones .
