Process for extracting gelatin from marine snail (Hexaplex trunculus): Chemical composition and functional properties

► This is the first report of the extraction of gelatin from marine invertebrate. ► The gelatin had high protein (88.62%) but low fat (0.77%) contents. ► The gel strength of the SMG was 103 g and contains a high number of imino acids. ► SMG have a good quality with desirable functional properties. ► Marine snail gelatin could be a useful additive in food materials.
