  What is this natural polymer anyway?

    Basically it is a protein substance obtained from the boiling of bones and connective tissue. But where does the raw material for gelatin come from ????.  You guessed it!  The meat industry where all that't left but the moo is converted to gelatin. The end result is a pale yellow, dry powder.  The powder is about 85% protein, 13% water, and 2% mineral salts.  It is free of additives and preservatives.  Gelatin contains about 18 different amino acids joined together in a chain.  Eventually a triple helix or triple spiral is the complex molecule that gives the polymer its unique ability to "gel" things.
