Heat & energy
How conduction, convection, radiation and water move heat through food.
COOKING SCIENCE · CORE CONCEPTS
Food Science Basics
The ideas that explain why ingredients change.
Cooking becomes easier to reason about when you understand the small number of scientific ideas that appear again and again. Proteins unfold and set, starches absorb water, fats carry aroma, emulsions keep unlike liquids together, and heat creates new textures and flavors. This hub is the starting point for those concepts.

What this hub covers
Start with the question or ingredient behavior you want to understand. These launch topics are editorial overviews until real child guides are published.
Proteins
Why proteins denature, coagulate, tenderize, foam and form new structures.
Starches
Gelatinization, thickening, retrogradation and the behavior of rice, potatoes and flour.
Emulsions
How oil and water can form stable sauces such as mayonnaise.
Browning
The Maillard reaction, caramelization and what heat does to flavor.
Water, salt & diffusion
Moisture, osmosis, brining, salting and why food dries or stays juicy.
Fermentation
How microbes transform milk, dough and other ingredients over time.
