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.
History of this great

Gelatin substances were first made during the fourteenth century.
People in France used it
as a source of protein during the English blockade in the war with Napoleon.
This first record of man making gelatin was about 1680 when a Frenchman,
Papin, cooked some bones and found the extract solidified.
"gelatin" is from Latin "gelatus" meaning stiff or frozen.
