    摘要: L-ascorbic acid tablets which contain more than about 90 weight percent of L-ascorbic acid and have a satisfactory mechanical strength can be obtained by spray-coating L-ascorbic acid powder capable of passing through a 200-mesh screen, with a solution of a binder under constant agitation in fluidized-bed granulating apparatus, until the amount of the binder has reached about 2 to about 4 weight percent relative to L-ascorbic acid, and compressing the resultant granules mixed with a lubricant into tablets.
