以下是引用梦不落在2006-6-5 12:42:00的发言:ding! I don't understand the sentence either the ancient Egyptians made only unleavened bread, such yeasts must frequently have been mixed into bread doughs accidentally. The Egyptians, however, did not discover leavened bread until about 3000 B.C. 文章这里得意思是,虽然E人经常误打误撞的放入酵母,但还是直到3000BC才发明了发酵的面包,答案给出了原因,因为之前用的那种面粉是经过烘烤的,失去了发酵需要的一种成分,再怎么加酵母都发酵不了,排除没有酵母的关系。所以,后来的面粉与发酵面包之间才能causally related |
