Abstract: Leavened yeast dough products obtain a long durability in a frozen condition by omitting using in the preparation thereof fermentable carbohydrates, but the formation in situ of such fermentable carbohydrates satisfactory to leaven the dough is ensured by adding one or more amylases to the dough. Upon freezing the activity of the amylase ceases and the concentration of fermentable carbohydrates falls to such a low value that the proteinase forming activity of the yeast actually ceases. A possibly desired brown-coloring of the baked product may be ensured by the addition of amylases with an activity at a relatively high temperature.
