Abstract
Petrovo uho (Haliotis tuberculata L.) je morski puž koji primarno naseljava istočnu atlantsku obalu, no nalazi ga se i u Mediteranu, a posebice u sjevernom Jadranu. Lovi se u komercijalne svrhe, a u Hrvatskoj se ne uzgaja. Njegov kemijski sastav ovisi o vrsti, hranidbi, području koje nastanjuje te salinitetu vode. Cilj ovog istraživanja bio je analizirati udio vode, mineralnih tvari, proteina, masti i masnih kiselina petrovog uha izlovljenog u sjevernom Jadranskom moru, kod zapadne Istre (Hrvatska) tijekom godišnjih doba kako bi se usporedile varijacije kemijskog sastava. Iz dobivenih rezultata možemo zaključiti da je najviši udio vode ljeti, dok je udio proteina i masti u tom periodu najmanji. Mononezasićene (MUFA) i zasićene masne kiseline (SFA) bilježe porast udjela tijekom ljeta, a smanjenje tijekom jeseni i zime, dok je udio polinezasićenih masnih kiselina (PUFA) ljeti manji u odnosu na jesen i zimu.
Abstract (english)
Abalone (Haliotis tuberculata L.) is a sea snail that primarily inhabits the eastern Atlantic coast, but is also found in the Mediterranean, especially in the northern Adriatic. It is hunted for commercial purposes, and is not cultivate in Croatia. Its chemical composition depends on the species, nutrition, the area it forms and the salinity of the water. The aim of this study was to analyze the content of water, minerals, proteins, fats and fatty acids of abalone caught in the northern Adriatic Sea, in western Istria (Croatia) during the seasons to compare variations in chemical composition. From the obtained results we can conclude that the highest content of water is in summer, while the content of protein and fat in that period is the lowest. Monounsaturated (MUFA) and saturated fatty acids (SFA) recorded an increase in the content during the summer and a decrease during the autumn and winter, while the content of polyunsaturated fatty acids (PUFA) in the summer was lower than in the autumn and winter.
