Yeast is used to make bread by fermenting the dough.
chemical
Its a chemical change because its changing what it is (from dough to bread)
A chemical change
Baking dough into bread is a chemical change because the heat causes chemical reactions to occur in the dough, leading to the formation of new substances such as carbon dioxide and water vapor, resulting in the transformation of the dough into bread.
It IS chemical, but it's not a heat reaction. It's respiration. Yeast is a living organism, which consumes sugar and excretes CO2 and alcohol. - - - - - chemical, because its reacting with heat & that always means chemical. it just includes a physical change..
The transformation of dough into bread involves both physical and chemical changes. The physical changes include the expansion of the dough during baking due to the release of gases, while the chemical changes involve the reactions between proteins and starches in the dough leading to the formation of a stable bread structure.
Yes, sourdough bread has a slightly tangy or sour taste due to the fermentation process that creates natural acids in the dough.
Leavened bread was made with ingredients possessing the chemical properties necessary to make dough rise
Pot of flour + jug/bucket of water = dough (pick bread dough).
Dough improver is actually called bread improver. it is used in bread making and can be bought in supermarkets. You add the bread improver into the dough and it will make a better loaf of bread.
A chemical change Because it takes plave in an oven and the yeast is rising without human help
