Denaturing is the process by which proteins essentially “unfold” and lose biological function. Typically, proteins can withstand a certain temperature before this happens. This nugget of truth has led folks to believe that incorporating protein powders into homemade recipes—such as protein bars, muffins, or other baked food—and cooking them will denature the proteins, rendering them ineffective.
Yes, the protein does get altered from the cooking heat, but the body will absorb the constituent amino acids just the same. The nutritional value remains constant, as well. In this regard, cooking protein powder is no different than cooking a piece of chicken, and who would want to eat raw chicken? You may now let out a sigh of relief and continue your regularly scheduled protein bake session.
