How is the gummy candy able to melt and then reform into a
gummy again? It is because of two ingredients in the seaweed
powder: carrageenan and agar-agar. They are what make a
gummy candy gummy!
WHAT MAKES
GUMMIES GUMMY?
GEEK
OUT!
CARRAGEENAN
Carrageenan comes from
certain types of red
algae and 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.
These molecules are called
polysaccharides. One key
property of this big tangled
web of molecules is its
ability to hold a lot of water!
When carrageenan is mixed
with water it forms what is
called a gel, or a 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
their web and become more
like a solid.
