Amino acid-containing granules

Amino acid-containing granules comprising an amino acid as a main component,

• wherein the amino acid-containing granules have an average particle diameter of 150 μm to 500 μm, and a homogeneity U of 0.70 or less, and
• wherein the average particle diameter and the homogeneity U are determined by the following measurement method:
• a) a volume-based particle size distribution in which data is plotted with a particle diameter as a horizontal axis and a content ratio (volume ratio) of particles as a vertical axis is obtained for the granules by a laser diffraction and scattering measurement method,
• b) the average particle diameter is determined from the volume-based particle size distribution, and
• c) the homogeneity U is determined by the following formula (1),

• wherein the amino acid includes L-arginine,
• wherein the amino acid-containing granules comprise thickening polysaccharide, and
• wherein the amino acid-containing granules have a bulk specific gravity of between 0.3 g/mL and 0.497 g/mL.
