Is scrambled eggs a chemical reaction?
Cooking the egg is an example of a chemical change.
Does cooking egg involve a physical and chemical change?

What causes a chemical reaction when you prepare scrambled eggs?
This harmless but unappealing color change is the result of a chemical reaction between iron in the pan and sulfur in egg whites. Don’t overcook. The heat retained in the pan will continue to cook and firm up the eggs after pan is removed from the heat.
Is toasting bread the Maillard reaction?
The browning process we call toasting is an example of the Maillard reaction, in which amino acids and sugars interact to produce the characteristic brown color, texture, and flavor we know as toast.
Is frying eggs a chemical change?

Is butter melting a chemical change?
Thus, melting of butter is a physical process because the physical appearance of the butter changes, the change is visible to eyes, the change can be reversed and no chemical change occurs.
Is frying potatoes a chemical change?
When cooked at high temperatures, sugars react with amino acids, including asparagine, in a chemical process known as the Maillard reaction. The reaction is what gives fried potatoes their prized flavor and color, but it is also what produces acrylamide. Upon harvesting, they sent some of the raw potatoes to labs.
Why are fried potatoes bad for you?
Acrylamide is “a chemical produced when starchy foods such as potatoes are fried, roasted or baked at a high temperature,” explained Schiff in an email. The browning process is actually a reaction that produces this chemical one shown to cause cancer in laboratory animals and considered toxic to humans, said Schiff.
The addition of iodine onto the potato immediately turn the potato a dark blue/black color. This is a chemical change. When starch in the potato combined with iodine (I2), it forms a starch /iodine complex which has a dark blue/black color.
