What is Jell-O®?
Dietary Gelatin is a long molecule called a polymer. Poly is a Latin word
that means 'many', and a 'mer' is a building block - chemically speaking. More
specifically, gelatin is a polypeptide. Polypeptides are polymers in which every
third mer unit is a Glycine molecule.
Gelatin is used in marshmallows and yogurt. It coats medicines to make
them easy to swallow. It is found in casinos - coating playing cards, and it
binds match heads together. It is used in forensic science to simulate human
tissue. Gelatin is also used to clarify beer after brewing.

Gelatin Manufacture
How is Jell-O® Made?
In their natural form, polypeptides are crystallized, and are called
collagen. Polypeptides occur in the hides, bones, and connecting tissue of
mammals. In collagen, polypeptides have a triple helix which is similar in
structure to DNA which is shaped as a double helix. Collagen is not watersoluble,
so it needs to be modified to make gelatin
The first step in the manufacture of gelatin from collagen is to dissolve the
collagen. This is done by boiling in either a strong acid, or a strong base.
During the process, the polypeptide molecules are broken in a process called
hydrolysis, and unraveled. Type A polypeptides from the acid process are a
little different from the type B polypeptides formed by the base process.
The next step is to neutralize the systems. Acid is added to the basic
solutions, and base is added to the acidic solutions. After this, some Jell-O® is
made at the plant. Hot water is added, and all the stuff that shouldn't be in
there (pig hair, bone chips, etc.) is filtered out. The next step is to boil off as
much water as possible, and then let it chill. After the Jell-O® is made, it is
dried and ground up.
What happens when I make Jell-O®?
Polypeptides, like Jell-O®, are soluble in water at high temperatures
(40C+), but not at lower temperatures. When a water solution of Jell-O® is
cooled, the molecules attempt to return to their triple helix state. This begins at
several points in the solution simultaneously. A given polypeptide chain is
likely involved in several short helices along its length. In order for one helix
segment to grow, it must unravel another helix. The final state is one in which
molecules are frozen in place, in a configuration that they would prefer not to
be. The molecules form a loose network in three dimensions, filled with fluid;
that is, if some of this fluid is removed, the network dries, and the gel shrinks.
If fluid is added, the network stretches, and the gel expands. It's not quite
stable, but it's not changing either so it is called 'metastable.'
