Investigation of macroelements in the muscle of four marine fish species


Author(s): Stefka Stoyanova

Abstract: For performing the investigation were taken six pieces from different species from the fish market in Varna during the period May 2017. The purpose of this study was to compare the content of macroelements Ca, K, P, Na and Mg in the muscle of the most consumed marine species in Bulgaria - mackerel (Scomber scombrus); European sprat (Sprattus sprattus); horse mackerel (Trachurus mediterraneus ponticus) and bluefish (Pommatomus saltatrix). Their amount (mg/kg) was measured by Atomic Absorption Spectrophotometer (AAS) at the Scientific Laboratory at Trakia University. Horse mackerel and mackerel have the highest levels of K and Ca (3384.81±43.12 mg/kg and 195.96±3.93 mg/kg) and P and Na (2436.68±24.74 mg/kg and 833.76±21.40 mg/kg), respectively, compared with these ones of the rest investigated species. The lowest amount of Ca (115.84±1.21 mg/kg), K (2635.63±13.58 mg/kg), P (2202.31±0.81 mg/kg), Na (527.99±19.73 mg/kg) and Mg (205.70±1.12 mg/kg) have mackerel, European sprat, bluefish, European sprat and bluefish, respectively. When comparing the mean values of each of the macronutrients depending upon the degree of accumulation in the meat samples of the tested fish, their concentration can be arranged in the following order: K (3007.64 mg/kg)> P (2314.51 mg / kg)> Na (625.24 mg/kg)> Mg (245.93 mg/g)> Ca (144.64 mg/g). The investigated and analised elements, according to their accumulation in the muscles of the studied fish were in the following order: K> P> Na> Mg> Ca. Research in this area provide the necessary information on the nutritional value of fish products in relation to healthy human nutrition.
