Gelatine is made by partly breaking down collagen, the main protein in the skin, bones and connective tissue of animals. It is present in jelly, most gummy candy and marshmallows, and it appears in sweets such as gummy bears and jelly babies.

What gelatine does

Gelatine absorbs 5 to 10 times its weight in water to form a gel, and that gel can be melted again by warming. Crucially for sweets, the upper melting point of gelatine is below human body temperature, which is important for the mouthfeel of foods made with it.

Gelatine is sold in grades of gel strength, measured with the Bloom test. Commercial gelatine has a strength of around 90 to 300 grams Bloom. Gelatine from fish has a lower melting and setting point than gelatine from beef or pork, and gelatine loses strength if it is held near boiling point for too long.

Gummy sweets and gelatine

Gelatine was not always the gummy sweet's ingredient. Gum arabic was the original base of gummy bears, which gave them their name. Today the traditional gummy bear is made from sugar, glucose syrup, starch, flavouring, colouring, citric acid and gelatine, and higher quality gummies have gelatine as the lead ingredient: see why are gummy bears shaped like bears?

In marshmallows, gelatine and egg white albumen are the two main proteins used to whip in air and hold the bubbles: see what are foam sweets made of?

Where it comes from

Most gelatine comes from pork skins, pork and cattle bones, or split cattle hides, and some from fish. Labels often just say gelatine: see beef gelatine and pork gelatine

Who avoids gelatine

The alternatives
