Date Oct. 24, 1996A process for producing calcium D-pantothenate, which comprises bringing a solution containing D-pantothenic acid directly produced by microbial fermentation into contact with activated carbon to adsorb the D-pantothenic acid to the activated carbon, eluting the D-pantothenic acid with a hydrophilic organic solvent, neutralizing the eluate with an alkali agent containing calcium to precipitate calcium D-pantothenate, and collecting the calcium D-pantothenate.
