[Amino acid composition of meat proteins in the Arctic reindeer]

Investigations have shown the proteins of the arctic venison to be of a high biological standard, since they contain all the essential amino acids. All the amino acids, except for tryptophan, were assayed with an automatic analyser, model HD-1200E, by following the generally accepted procedure afer an acid hydrolysis. Tryptophan was assayed after alkaline hydrolysis. A total of 17 amino acids were determined in the raw and cooked meat. The content of essential amino acids is as great as 50.7 per cent of the protein weight. Heat treatment does not have any essential effect on the content of amino acids. As regards their amino acids composition the proteins of the arctic vension stands close to that of the beef and horse-flesh proteins.
