Anything being "toasted" is a chemical change. The browning that occurs is due to a type of chemical reaction called the "Maillard reaction." It's a reaction between amino acids (in proteins) and carbohydrates (sugars and starch) that give cooked foods their characteristic flavor.Another reaction that sometimes occurs when cooking foods is caramelization, which is similar in appearance but is a completely different reaction ... it's the pyrolysis of certain sugars.
