Sad story....what does 'denature' mean? Is this actually a technical
term, maybe misused, or misapplied?
Heather,
In my nutrition class, we talk about "denature" when we talk about
proteins. To denature a protein is to change it's conformation or shape.
Protein can be denatured by heat (as in the change you see when an egg
is cooked), acid (adding vinegar or lemon juice to milk-- it curdles),
or heavy metals. I'm not aware that freezing denatures protein. I am
also wondering what the authors of that information think happens to the
cow colostrum when it is pasturized.
