Abstract

The meat of the African sharptooth catfish has a variability in indicators of nutritional and biological value, depending on the physiological state of fish. The aim of the study was to compare the nutritional and biological value of african sharptooth catfish meat during the spawning and inter-spawning period. The object of the study is muscle tissue of the african sharptooth catfish at the age of 12 months. The assessment of organoleptic properties and indicators of nutritional and biological value of the muscle tissue of the african sharptooth catfish during the spawning and inter-spawning period was carried out. The organoleptic properties of the african sharptooth catfish during the inter-spawning and spawning periods did not differ significantly. It was found that the criteria for the nutritional value of african sharptooth catfish meat in the inter-spawning period significantly exceed similar indicators during the spawning period. The meat of the african sharptooth catfish in inter-spawning period includes more fat and protein, therefore, is characterized by less water content. The biological value of meat is determined by the content of amino acids in it. During the inter-spawning period, the amount of all amino acids in the meat of African clarias significantly increases. The dominant position of essential amino acids is occupied by lysine and tryptophan. This is of exceptional importance for a living organism. Tryptophan is indispensable in the synthesis of vitamin B3, which has a vasoprotective effect, reduces cholesterol and provides prevention of hypoxia of cells and tissues. Lysine is a source of carnitine, stimulates mitosis, provides prophylaxis of osteoporosis, and stimulates bone regeneration. According to research, lysine can prevent the development and ease the course of Alzheimer’s disease. Eating foods with high levels of tryptophan and lysine ultimately improves the quality of life. The high content of lysine and tryptophan makes it possible to attribute african sharptooth meat to an indispensable component of children’s and sports nutrition.
