Determining the suitable mollusk species for pharmaceutical and food industries using sterol and fatty acid profiles of four marine mollusc species from Qeshm coast

This study aims to investigate the profile of sterols and fatty acids of four species of molluscs (rock oyster bivalve; Saccostrea cuculate, clam bivalve; Callista umbonella and cylindrical clam; Solen vagina) and one edible snail species. (Ampullaria cuprina) and determining the best mollusc species of Qeshm beach has been designed. Mollusc species (100 each) were kept in cold boxes with ice and transferred to the laboratory, and the content of fatty acids and mollusk sterols were analyzed with the help of gas chromatography. The highest amount of myristic acid (14:0), lauric acid (12:0), pentadecanoic acid (15:0), heptadecanoic acid (17:0), stearic acid (18:0) and total saturated fatty acids in snail Edible and lowest myristic acid (14:0), palmitoleic acid (16:1), pentadecanoic acid (15:0), heptadecanoic acid (17:0) and stearic acid (18:0) in rock oyster bivalves was observed. The lowest amount of cholesterol and the highest amount of 5 and 12 stigmadranol, campastonol, stigma sterol, delta 7 campestrol and delta 5 onasterol were also observed in edible snail. This study emphasized the difference in the profile of sterols and fatty acids of four selected mollusk species, and the best profile of sterols and fatty acids was observed in the edible snail, which can be suggested for the production of various health products in the pharmaceutical and food industries.
