Our study shows that all cooking methods caused great losses of total soluble proteins and soluble sugars, particularly the boiling and stir-frying/boiling that use a great amount of water. It is possible that soluble proteins and soluble sugars in broccoli were lost by leaching to surrounding water.
Does broccoli lose nutritional value when cooked?
Broccoli, spinach, and lettuce may lose up to 50% or more of their vitamin C when boiled ( 4 , 5). Because vitamin C is water-soluble and sensitive to heat, it can leach out of vegetables when they’re immersed in hot water. B vitamins are similarly heat sensitive.
Does protein decrease when cooked?
Proteins are not lost during cooking as easily as vitamins; however overcooking and cooking at extremely high temperatures will denature proteins found in food. When cooked or agitated (as occurs when egg whites are beaten), proteins undergo physical changes called denaturation and coagulation.

Does heat destroy protein?
When protein is heated, it can ‘denature’– this means the protein molecules unfold or break apart. This is what your body does to protein anyway, breaking down the amino acids and digesting protein. Much like when you cook meat, the protein you gain is not altered by cooking.
What happens to protein during cooking?
During cooking, when the proteins are heated, the molecules become agitated and move around causing the intermolecular bonds between molecules to be broken. This allows the protein to denature (change shape) which changes the texture of foods. This explains the difference in structure between a raw egg and a fried egg.
Does cooking eggs reduce protein?
Does Cooking an Egg Reduce Its Protein? The way you prepare the egg has no effect on the amount of protein the egg originally contains, but it does have an effect on how much of the protein in the egg you absorb from the egg.
