下面是美國官方對活性干酵母的定義:
96.2 Active Dry Yeast is yeast which has been dried in such a manner as to preserve a large portion of its fermenting power. It must contain no added cereal or filler and must contain not less than 15 billion live yeast cells per gram. (Adopted 1951)
INF 7-05-524 Yeast active dehydrated
