A composition for accelerating calcium absorption which contains a less absorbable L-form aldonic acid, a salt thereof, or a less absorbable L-form aldonolactone; and a food or beverage which contains L-arabonic acid, a salt thereof, or L-arabonolactone. Also provided is a process for producing L- arabono-.gamma.-lactone crystals, characterized by dissolving L-arabonic acid in an organic solvent and crystallizing the lactone from the solution. Thus, a food or medicine effective in the prevention or treatment of osteoporosis can be provided.

L~invention porte sur une composition d~accélération d~absorption de calcium contenant un acide aldonique de forme L moins absorbable, un sel de celui-ci ou un aldonolactone de forme L moins absorbable ; et un aliment ou une boisson contenant un acide L-arabonique, un sel de celui-ci ou un L-arabonolactone. L~invention porte également sur un procédé de fabrication de cristaux de L-arabono-.gamma.-lactone, caractérisé par la dissolution d~acide L-arabonique dans un solvant organique et cristallisation de lactone à partir de la solution.
