Abstract
The present invention relates to a process for reducing the excretion of nitrogen from humans and animals while maintaining formation of proteins, as well as a food and feedstuff for humans and animals comprising keto acids, whereby ingoing protein is replaced by alpha ketoglutaric acid; a combination of alpha keto glutaric acid and pyruvic acid; oxaloacetate or oxaloacetate in combination with alpha keto glutaric acid or pyruvate or another keto acid according to the formula R--CO--COOX, wherein R denotes a part of a non-essential amino acid and X denotes hydrogen, alkali metal, alkaline earth metal or organic base or non-toxic precursors or intermediates of these, whereby the keto acid (-s) is (are) present in an amount of 1 to 20% by weight, preferably 1-10% by weight of the protein dry matter present.
Claims23
A process for reducing the excretion of nitrogen from humans or animals while maintaining protein formation, said process comprising administering to said humans or animals food and/or feedstuff wherein protein from said food and feedstuff has been replaced by at least one keto acid of a non-essential amino acid according to the formula R--CO--COOX, wherein R is a part of a non-essential amino acid and X is selected from the group consisting of hydrogen, an alkali metal, an alkaline earth metal or an organic base, wherein said keto acid is present in an amount of 1 to 20% by weight of the protein dry matter present and wherein nitrogen excretion is substantially reduced.
A food and/or feedstuff composition for humans or animals comprising protein from said composition replaced by at least one keto acid of a non-essential amino acid according to the formula R--CO--COOX, wherein R is a part of a non-essential amino acid and X is selected from the group consisting of hydrogen, an alkali metal, an alkaline earth metal or an organic base, wherein said keto acid is present in an amount of 1 to 20% by weight, which composition is capable of substantially reducing nitrogen excretion.
