How is the gummy candy mix able to form into a squishy candy
when mixed with water? An ingredient called gelatin makes
this possible. This is what makes a gummy candy gummy!
WHAT MAKES
GUMMIES GUMMY?

GELATIN
Gelatin is an animal protein made
from bones and connective tissues.
It has the ability to swell up in cold
water and to dissolve when heated.
And, when it cools off again, it
forms a reversible gel — short for
gelatinous substance. Gels contain
mostly liquids, but behave more
like solids. When you heat up a gel,
the molecules start moving around
more which lets them slide past
each other more easily. This causes
the gel to become more like a liquid.
But when you cool the gel back
down again, the molecules re-form a
web-like structure and become more
like a solid. A reversible gel is one
that can return to an earlier state.
Gelatin contains long
molecules that are made up of many
repeating parts, like the links of
a chain. Each molecule can also
connect to other long molecules,
forming a web. The general term for
this type of molecule is “polymer.”
Gelatin contains a specific type of
polymer called collagen.
One key property of this big
tangled web of molecules is its
ability to hold a lot of water! Parts of
a collagen molecule are responsible
for its firm structure, while other
parts bond with water molecules.
In warm water, the water molecules
can slide in between the collagen
molecules and fold their inner
structure together. This happens
when the gelatin is dissolved. When
cooled off, the collagen molecules
connect themselves together again
and as a result form a network that
can make liquids firm.
