Abstract
Granulars and multi-vitamin tablets of thiamine and ascorbic acid were prepared using thiamine hydrochloride, thiamine mononitrate and thiamine dicetylsulfate. Granulars were stored at 37℃, 85% relative humidity for about 30 days and tablets were stored at room temperature for about six months, and their stabilities were compared. The stabilities of both thiamine and ascorbic acid were found to be independent of the kinds of thiamine salts, but the preparations used thiamine dicetylsulfate showed the highest stability for both thiamine and ascorbic acid.
