Chemistry in the Kitchen

Cooking Up Science

Chemistry is at work every time you cook or bake! Heating, mixing, and combining ingredients all lead to chemical reactions and changes in the properties of matter.

  • Baking soda makes cakes rise through a reaction with acids.
  • Caramelizing sugar involves breaking chemical bonds and forming new, tasty compounds.
  • Boiling, freezing, and melting are all physical changes involving energy.

Why It Matters

Understanding kitchen chemistry helps you create better recipes, avoid kitchen disasters, and even invent new foods.

Examples

  • Bread dough rises because yeast produces carbon dioxide during fermentation.

  • Eggs solidify when cooked due to the denaturation of proteins.
