Step 1
Physical change
Answer
One physical change that occurs during the cooking of food is the tenderizing of meat. As meat is cooked, the proteins break down, resulting in a change in texture, making the meat softer and easier to chew. Additionally, there may be an increase in size as the meat absorbs moisture, contributing to its juiciness.
Step 2
Chemical change
Answer
A significant chemical change that occurs during cooking is the Maillard reaction. This reaction takes place between amino acids and reducing sugars when food is heated, resulting in browning and the development of complex flavors. This is especially noticeable in roasted meats and baked goods, providing a rich aroma and enhanced taste.
