After reading other posts I had to look up Jello:

If you've ever eaten in a cafeteria, chances are good that your dessert options included Jell-O. There are hundreds of different desserts that use Jell-O to create everything from your basic institutional-style gelatin square to ornate designs that incorporate varied Jell-O flavors, fruit, and whipped toppings. Jell-O consists of four basic ingredients:
- gelatin
- water
- sugar or artificial sweetener and artificial flavors
- food coloring

The gelatin you eat in Jell-O comes from the collagen in cow or pig bones, hooves, and connective tissues.
The
gelatin in Jell-O is what lets you transform it into all sorts of different shapes. What exactly is gelatin? Gelatin is just a processed version of a structural
protein called
collagen that is found in many animals, including humans. Collagen actually makes up almost a third of all the protein in the human body. It is a big, fibrous molecule that makes skin, bones, and tendons both strong and somewhat elastic. As you get older, your body makes less collagen, and individual collagen fibers become crosslinked with each other. You might experience this as stiff joints (from less flexible tendons) or wrinkles (from loss of skin elasticity).
The gelatin you eat in Jell-O comes from the collagen in cow or pig bones, hooves, and connective tissues. To make gelatin, manufacturers grind up these various parts and pre-treat them with either a strong acid or a strong base to break down cellular structures and release proteins like collagen. After pre-treatment, the resulting mixture is boiled. During this process, the large collagen protein ends up being partially broken down, and the resulting product is called gelatin. The gelatin is easily extracted because it forms a layer on the surface of the boiling mixture.

Where can you find gelatin?
Gelatin is a common ingredient in foods because it is so versatile. It can be used as a
gelling agent (as in Jell-O), as a
thickener, an
emulsifier, and a
stabilizer. You'll find it in a variety of foods, from yogurt to chewing gum. Here is a list of some other foods that commonly contain gelatin:
- gummy bears
- sour cream
- cream cheese
- cake icing and frosting
- marshmallows
- soups, sauces and gravies
- canned ham and chicken
- corned beef
- sausage
Gelatin is even used to make the coating for pills that makes them easier to swallow. It's also in cosmetics, lozenges, and ointments.
