The amino acid profile of 11 samples of tiger nuts ( Cyperus esculentusL.) grown in the area of “L'Horta Nord” in Valencia (Spain) and one sample of African origin were determined, along with the amino acid contents of 10 samples of natural orgeat from Valencia. Protein was hydrolysed by hydrochloric acid at 110 °C for 23 h, and amino acids were derivatised with AQC and determined by RP-HPLC with fluorescence detection. The chromatographic conditions were optimised. The analytical parameters (detection and quantification limits, precision and accuracy) showed the method to be sufficiently sensitive and reproducible for determining amino acids resistant to acid hydrolysis in tiger nuts and orgeat. Arginine was the most abundant amino acid in both tiger nuts and orgeat and the lowest contents corresponding to histidine and tyrosine. The essential amino acid contents of tiger nuts and orgeat protein were greater than those proposed in the protein standard for adults by the FAO/WHO, with the exception of histidine. No significant differences were found among the arginine, lysine and isoleucine amino acid contents in tiger nuts from Valencia, Alboraya and Alm‡ssera; nor were they found among amino acids in tiger nuts from Valencia and Alm‡ssera, with the exception of tyrosine.

Отрасль птицеводства играет ведущую роль в обеспечении населения полноценными продуктами питания. Признавая тот факт, что продуктивность сельскохозяйственной птицы напрямую зависит от уровня кормления, учёным приходится изыскивать резервы кормовой базы для полноценного обеспечения гранулы комбикорма всеми необходимыми питательными элементами. Нами был изучен аминокислотный профиль многокомпонентного регуляторного комплекса «Байпас», который полностью восполняет потребность птицы в аминокислотах. Нашими исследованиями установлено, что ядро аминокислотной составляющей кормовой добавки представляют три аминокислоты: аргинин, глицин и лизин. В целом кормовая добавка содержит 13 аминокислот, что положительно отразится на усвоении питательных элементов комбикорма, а, следовательно, на продуктивности сельскохозяйственной птицы. The poultry-rearing industry plays a leading role in providing the population with balanced food products. Recognizing the fact that the productivity of agricultural poultry directly depends on the level of feeding, scientists have to find reserves of the fodder base to fully provide the compound animal feedstuff pellets with all the necessary nutrients. We have studied the amino acid profile of the multicomponent regulatory complex "Baipas", which fully meets the need for amino acids in poultry. Our researches have found that the nucleus of the amino acid component of the feed additive is represented by three amino acids: arginine, glycine and lysine. In general, the feed additive contains 13 amino acids, which will positively affect the absorption of nutritional elements of compound animal feedstuff, and, therefore, the productivity of poultry.
