Nutritional Value of Lemnaceae Macrophytes
Аннотация
In this article, the separation of dry mass from the wet biomass of Lemna minor and Lemna gibba, the dry mass and the preservation of protein and the amount of amino acids in it were investigated. In particular, it was determined that Lemna minor forms an average of 5.21% dry weight, Lemna gibba an average of 6.03%. It was noted that grown 1 m2 of Lemna minor forms an average of 1,429.83 g, 274.53 g is obtained from it, Lemna gibba forms an average of 1628.00 g, 268.91 g is obtained from it. Having examined the composition of the dry mass, it was noted that, Lemna minor synthesizes - 16.10%, Lemna gibba synthesizes 15.02% of the protein. Essential amino acids in the purified duckweed protein have been investigated. Here, in the composition of purified proteins obtained from Lemna minor, threonine is 5.03; valine - 7.59; methionine - 0.39; isoleucine -5.83; leucine - 10.16; tyrosine - 2.73; phenylalanine 6.21 and lysine 6.13 mg/100 mg, in the composition of purified proteins obtained from Lemna gibba threonine 4.75; valine - 7.36; methionine - 1.23; isoleucine -5.74; leucine - 10.61; tyrosine - 4.32; phenylalanine 6.60 and lysine 6.13 mg/100 mg. Therefore, to determine the true nutritional value, it is necessary to isolate pure protein from the dry mass and to study the composition of the amino acid in the protein.
