May Muslims eat gelatine?
Yes. Gelatine is produced through intense heat and pressure, and in the process it becomes a new substance. Something whose very nature has been fundamentally transformed no longer falls under the prohibition of the original substance.
When it comes to food, permitted and forbidden belong to the realm of the living, that is, the flesh and tissue of certain animals. The verse above names these things. Gelatine, however, is no longer living tissue. It is produced under great heat and high pressure, and the end result is a chemically transformed substance.
An everyday example makes this clear. Beautiful fruit and vegetables grow in fields fertilised with manure. Manure is unclean, and nobody would eat it. Yet the plant transforms it completely. What grows from it is something new, and nobody considers a tomato unclean for that reason.
By the same principle, a substance that has changed fundamentally in its nature and its chemistry is no longer the same thing that was originally forbidden. This also applies to gelatine. It has become a new substance, and such substances are not forbidden.
So anyone who has so far avoided sweets, desserts or other foods containing gelatine with an uneasy conscience can be at ease. Islam does not make life difficult on this point. It forbids little and declares all good things permitted, as the second verse above says.
