Abstract
[Problem] A valine, isoleucine, leucine mixture which is excellent in the reduction of bitter taste and improved dissolution speed is provided. [Solving Means] The above problem is solved by a solid solution composed of three amino acids of valine, isoleucine, leucine, and a solid solution composed of these and at least one of acid selected from the group consisting of neutral aliphatic amino acid, neutral hydroxy amino acid, neutral acid amide amino acid, acidic amino acid, basic amino acid, hydroxy acid.

A solid solution composed of three amino acids of valine, isoleucine, leucine.
A solid solution composed of valine, isoleucine, leucine and at least one of acid selected from the group consisting of neutral aliphatic amino acid, neutral hydroxy amino acid, neutral acid amide amino acid, acidic amino acid, basic amino acid, hydroxy acid.
A method of manufacturing a solid solution composed of three amino acids of valine, isoleucine, leucine, which comprises concentrating an aqueous solution of 0.3-10.0 w/w % of valine, 0.3-6.5 w/w % of isoleucine, 0.3-4.0 w/w % of leucine at 40-90° C. under a pressure of 3 kPa-30 kPa to crystallize, cooling the concentrated solution to 15-25° C., and then separating crystals.
A method of producing a solid solution containing valine, isoleucine, leucine and at least one of acid selected from the group consisting of neutral aliphatic amino acid, neutral hydroxy amino acid, neutral acid amide amino acid, acidic amino acid, basic amino acid, hydroxy acid, which comprises crystallizing using a solution containing valine, isoleucine, leucine and at least one of acid selected from the group consisting of neutral aliphatic amino acid, neutral hydroxy amino acid, neutral acid amide amino acid, acidic amino acid, basic amino acid, hydroxy acid.
