Title
(EN) COMPOSITION CONTAINING READILY ABSORBABLE CALCIUM AND PROCESS FOR PRODUCING THE SAME
(FR) COMPOSITION CONTENANT DU CALCIUM FACILEMENT ABSORBABLE ET SON PROCEDE DE FABRICATION
Abstract
(EN)
A composition containing readily absorbable calcium which comprises a calcium salt and 0.2 to 5 % by weight, based on the calcium contained in the calcium salt, of chondroitin sulfate. A calcium salt preferably used in this composition can be obtained by, for example, baking the external skeleton of sea urchin in an oven to thereby give calcium oxide, hydrating it into calcium hydroxide and then reacting it with an organic carboxylic acid to thereby give a calcium salt. The absorption of calcium $i(in vivo) is highly promoted by adding chondroitin sulfate. The calcium may be any one origninating in various natural and synthetic sources.
(FR)
On décrit une composition contenant du calcium facilement absorbable, constituée d'un sel de calcium et de 0,2 à 5 % en poids de sulfate de chondroïtine, ce pourcentage étant établi sur la base de la quantité de calcium contenue dans le sel de calcium. Le sel de calcium que l'on utilisera de préférence dans cette composition peut être obtenu, par exemple, de la façon suivante: on cuit dans un four la coque d'un oursin afin d'obtenir de l'oxyde de calcium, on hydrate ensuite cet oxyde afin d'obtenir de l'hydroxyde de calcium, puis on met en réaction cet hydroxyde avec un acide carboxylique organique, et on obtient ainsi le sel de calcium. L'absorption du calcium $i(in vivo) est hautement favorisée par l'adjonction du sulfate de chondroïtine. Le calcium utilisé peut être de n'importe quelle orgine naturelle ou synthétique.
