What happens when you bake something?

Is baking chemical or physical change?

When you bake a cake, the ingredients go through a chemical change. A chemical change occurs when the molecules that compose two or more substances are rearranged to form a new substance! When you start baking, you have a mixture of ingredients.

What kind of changes occur in baking?

rise, as a result of fermentation (an irreversible chemical change). Yeast transforms the sugar in the dough into carbonic gas (carbon dioxide) and alcohol (ethanol). The trapped carbon dioxide makes the dough rise, and the alcohol produced by fermentation evaporates during the baking process.

What chemical reaction happens when you bake cookies?

When the batter heats up, the sucrose (sugar) breaks down into glucose and fructose, forming a polymer chain, giving the cookie its light brown, shiny crust. When sodium bicarbonate (baking soda) heats up, it causes a chemical reaction: 2NaHCO3 ? Na2CO3 + H2O + CO2.

How does heat affect baking?

Generally speaking, higher temperatures will give your bakes a more golden, crisper crust to the sponge or pastry and a low temperature will result in a fluffier, less golden sponge. With some cakes, you want a golden crust and with other cakes you want them to be gently cooked and fluffy.

What makes a cake light and fluffy?

Creaming simply means beating butter with sugar until light and fluffy, trapping tiny air bubbles. The air bubbles you’re adding, plus the CO2 released by raising agents, will expand as they heat up, and the cake will rise.

Is cooking a chemistry or physics?

Cooking is chemistry

Cooking itself is really just chemistry. Heating, freezing, mixing and blending are all processes used in the laboratory and the kitchen. When we cook food, a myriad of different physical and chemical processes simultaneously take place to transform the ingredients (i.e. chemicals) involved.

Why baking is a mathematics?

You need to increase and decrease both the temperature and time. Math is used in every step of baking. It is a helpful tool when preparing baked goods. Bakers need to use math when measuring and weighing ingredients ,changing recipes and temperatures.
