Background. The urgent task is the effective use of domestic aquatic stocks, the development of aqua and mariculture to obtain products of the predicted quality level. Black Sea dogfish tar may be a promising raw material for the domestic food industry.
The low efficiency of food use of dogfish tar is due to the lack of modern systematic studies of the functional suitability of fishery raw materials to substantiate recommendations for the comprehensive and safe processing of multi-species individuals of the Black Sea dogfish tar.
The aim of the work is a criterion-factor assessment of the mineral composition of the age-old individuals of the Black Sea dogfish tar.
Materials and methods. The object of the study is the Black Sea dogfish multi-species, caught in the Black Sea in November – February 2013–2016.
The mass-dimensional characteristics of the tar dogfish were estimated by absolute (kg) and relative (index, %) indicators of body parts mass. The content of moisture, ash, fat, protein is determined by current standards.
The mineral elements were determined by atomic emission spectrometry on an Optima 2100 DV device (USA).
A series of dogfish meat samples at a depth of 4.0 (sample 1) and 1.5 (sample 2) cmfrom the surface of the body were selected to analyze the chemical composition of mature dogfish individuals.
Results. Size and mass characteristics depend on the age of the dogfish tar and it is advisable to use mature individuals aged 13–15 years.
The investigated chemical composition of the Black Sea dogfish depends on the size, mass and age characteristics. With age, the dogfish body has a decrease in water content of 5.4 % and an increase in protein content of 4.1 % and fat by 1.2 %.
The meat of young Black Sea dogfish individuals is relatively high in potassium and sodium. With age, there is a significant decrease in the content of Potassium and Phosphorus in mature dogfish tar individuals – by an average of 197.0 and 71.4 %, respectively. There was a slight increase in the content of Magnesium and Ferum in mature individuals of dogfish tar compared with young ones – by 2.6 and 2.7 %, respectively.
In general, in mature dogfish individuals, the tar content of all mineral elements except iodine is greater in the surface layers of meat compared to the deep layers.
Conclusion. It is established that the chemical and mineral composition of the Black Sea dogfish depends on the size, mass and age characteristics. With age in the dogfish body, tar has seen an increase in protein and fat content and a decrease in water content.
Regardless of the age of the dogfish, the mineral content of the meat is characterized by a high content of Potassium, Sodium, Ferum and Magnesium.
