Abstract
L-valine granules are produced by adding L-glutamic acid to an aqueous solution containing L-valine so that the amount of L-glutamic acid is 0.5% by weight or more relative to the L-valine, dissolving the L-glutamic acid, then adjusting the pH of the aqueous solution to an acidic level and then crystallizing the L-valine.
