What does “un denatured” mean as applied to whey and colostrum?
To denature something is to deprive it of its natural character, properties, etc. In biochemistry it means to treat (a protein or the like) by chemical or physical means so as to alter its original state. In the case of whey, in the processing and purification and pasteurization, too much heat for too much time “cooks” some the bioactive peptides so as to deactivate them. When this happens much of the antioxidant, detoxification and immune support undenatured whey supplies is lost.
