Isoelectric focusing of sarcoplasmic proteins to distinguish swordfish, blue marlin and Mediterranean spearfish

Comparison of Proximate, Fatty Acid and Amino Acid Compositions of Various Types of Fish Roes

“…Amount of ash has been reported as 7.0% in the literature similar to our results. [28,29] It has been determined that; waxed mullet roes contain significantly higher (p < 0.05) amount of ash than black caviars. The ash content of salted mullet roe has been determined as 7.2 g/100 g roe and this value has been measured as 10.1 g/100 g roe after waxing by 8engör et al [27] Therefore, it has been mentioned that ash content increase after waxing.…”

Electrophoretic Methods for Identifying the Species of Seafood and Its Derivatives

“…Based on their research, Renon et al (2005) concluded that IEF is an easy and dependable way to spot blue marlin steaks that have been interchanged for Mediterranean spearfish (Tetrapturus belone) and cold-smoked swordfish (Xiphias gladius) fillets that have been fraudulently switched out for lower-value blue marlin (Makaira mazara).…”

Species identification in anchovy pastes from the market by PCR-RFLP technique

“…With regard to possible difficulties especially in products having undergone strong processing technologies, at present there are several analytical techniques available which can be used to identify fish species and the scientific progress is continuous in this field: electrophoresis methods, like IEF (Ataman, Çelik, & Rehbein, 2006;Berrini, Tepedino, Borromeo, & Secchi, 2006;Esteve-Romero, Malmheden Yman, Bossi, & Righetti, 1996;Renon, Bernardi, Malandra, & Biondi, 2005), even followed by specific enzyme staining (Piñeiro, Barros-Velasquez, Pérez-Martin & Gallardo, 2000), SDS-PAGE (Piñeiro et al, 1999) and 2-D electrophoresis (Ataman et al, 2006;Berrini et al, 2006;Martinez & Jakobsen Friis, 2004;Sotelo, Piñeiro, Gallardo & Pérez-Martin, 1992), also combined with mass spectrometry (Piñeiro, Vazquez, Marina, Barros-Velasquez, & Gallardo, 2001); chromatography, such as HPLC (Armstrong, Leach, & Wyllie, 1992;Knuutinen & Harjula, 1998); immunological techniques, such as ELISA (Asensio, Gonzalez, Garcia, & Martin, 2008;Asensio et al, 2003;Cespedes et al, 1999;Taylor, Patel, & Jones, 1994) and western blotting (Lopata, Luijx, Fenemore, Sweijd, & Cook, 2002;Ochiai & Watanabe, 2003); biomolecular methods, such as RAPD (Bossier, 1999;Liu, Li, Argue, & Dunham, 1999;Partis & Wells, 1996), AFLP (Bossier, 1999;Zhang, Wang, & Cai, 2007), sequencing (Bernardi, Colombo, & Cantoni, 2005;Inoue, Miya, Tsukamoto, & Nishida, 2001;Jerôme, Lemaire, Bautista, Fleurence, & Etienne, 2003;Kyle & Wilson, 2007;Manchado, Catanese, & Infante, 2004;…”
