When food is fried in heated oil, moisture forms vapor, which evaporates in a bubbling action and gradually settles as the food is fried. Water, vapor, and oxygen initiate a chemical reaction between the fried food and the food.
Is frying a egg chemical change?
Cooking eggs is an example of a chemical change.
Why cooking is a chemical change?
Cooking food is a chemical change because it involves a change in the composition of the food. After cooking, the raw ingredients of the vegetable cannot be regained. Was this answer helpful?
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 important flavor and color, but it is also what produces acrylamide.
