Abstract. In the article the problem of search for an alternative source of a protein for food is considered. Studying amino-acid structure of larvae of Zophobas morio and their assessment in terms of full value of protein was the purpose of work. The larvae of Zophobas morio (n=100) were material for a research. The Kjeldal’s method of protein definition according to GOST 25011 and the chromatographic method of amino-acid structure determination according to M-02-902-142-07 were used in this work. As a result, it was established that the mass fraction of the protein was equal in the test sample Zophobas morio to 19.0±0.06% that is comparable to amount of protein in beef and pork, in various parts of broilers, in fillet of a turkey and meat of quails. As a result of studying the amino acid profile of larvae of Zophobas morio, it was found that they contain replaceable amino acids (∑=21,043±0,003 g/100 g on a dry basis), all 8 essential amino acids (∑=14,257±0,02003 g/100 g on a dry basis) and 2 partially replaceable amino acids – argigin and histidine (∑=4,766±0,01050 g/100 g on a dry basis). Glutamic acid quantitatively prevailed over the rest (5,068±0,0095 g/100 g on a dry basis), among the essential amino acids, the maximum methionine content (2,662±0,0060 g/100 g on a dry basis) and the minimum tryptophan content (0,562±0,0085 g/100 g on a dry basis) were noted. The limiting amino acid in larvae of Zophobas morio is the lysine, other amino acids have the score more than 100%. On the amino-acid profile Zophobas morio lose to beef, and on the content of separate amino acids are identical to pork and meat of birds. On coefficient of distribution of amino acids and biological value of a larva of Zophobas morio considerably concede to meat of animals and birds, and on a proteinaceous quality indicator – pork and meat of birds. To sum up, Zophobas morio can serve as fine raw materials for receiving as irreplaceable, especially methionine and threonine, and replaceable amino acids.

Keywords: larvae of Zophobas morio, mass fraction of protein, amino acid.
