Kitchen Science Glossary
Clear definitions and simple explanations of key terms in cooking, baking, and recipe preparation.
Maillard Reaction
A cascade chemical reaction between building amino acids and reducing sugars under thermal excitation.
Responsible for complex deep savory golden brown colors and roasted flavor compounds in baked goods, seared steaks, and toasted grains.
Pyrolysis
The thermal decomposition and oxidation of organic substances (sugars) at extreme high temperatures in the absence of high moisture.
The chemical engine behind caramelization. Differs from Maillard browning as it involves only carbohydrate rings without proteins.
Starch Gelatinization
The heating of starch granules in the presence of water, causing them to absorb moisture, swell, burst, and form a thick gel network.
Crucial for thickening gravies, roux, puddings, or establishing structural cells in baking bread crumb loaf profiles.
Lipid Emulsification
The stable suspension and blending of naturally hydrophobic fats inside polar liquids (like water) using biological binders.
Utilized extensively in egg yolks (lecithin) or mustard mucilages to prevent vinaigrettes, mayonnaise, and batters from breaking.
