E428: Gelatine

What is E428?

Gelatine, sometimes listed as E428 in databases, is a protein obtained from collagen, the main structural protein in skin, bones and connective tissue. Dissolved in warm water it forms a characteristic elastic gel that melts at body temperature.

Origin and production

It is made by partially breaking down collagen from animal by-products, mainly pig skin, cattle hides and bones, and to a lesser extent fish skin and scales.

Why is it used?

Gelatine gives the chewy texture to gummy sweets and marshmallows, sets desserts and jellies, stabilises some yogurts and mousses, and forms the shells of many capsules and supplements. It is also used in some places to clarify wine and juice.

Vegan, vegetarian and halal

Gelatine is an animal product and is not suitable for vegans or vegetarians. Its acceptability for halal or kosher diets depends on the animal source and processing, so people following these diets typically look for certified bovine or fish gelatine.

Safety and regulation

In the EU, gelatine is regulated as a food ingredient rather than an authorised additive, so it is normally listed by name without an E-number. It is subject to food safety rules governing the raw materials and production process.
