Weathered reef-building coral is immersed in an aqueous alkali solution under reduced pressure to carry out alkali washing to make the aqueous alkali solution penetrate into the weathered reef-building coral throughout its fine structure inside the porous tissue, which is subsequently washed with water until a washing from the inside of the porous tissue is neutralized. As a result of this washing, various marine algae, various microorganisms including Vibrio bacteria inhabiting the ocean and other various organic substances held in the inner fine structure of weathered reef-building coral can be removed. Thus, a weathered reef-building coral material can be obtained whose safety has been ensured. This weathered reef-building coral material is suitable for food materials, filter mediums for water purifiers and so forth.
Des coraux hermatypiques effrités sont immergés dans une solution alcaline aqueuse sous une pression réduite afin d'être soumis à un lavage alcalin qui fait pénétrer la solution alcaline aqueuse dans la structure fine à l'intérieur du tissu poreux des coraux hermatypiques effrités. Le tissu poreux est ensuite lavé avec de l'eau jusqu'à neutralisation de l'eau de lavage de l'intérieur du tissu poreux. Ce lavage permet d'enlever diverses algues marines, divers microorganismes, y compris les bactéries Vibrio habitant l'océan et d'autres substances organiques diverses retenus dans la structure fine interne des coraux hermatypiques effrités. Ainsi, il est possible d'obtenir des coraux hermatypiques effrités qui ne présentent aucun danger. Cette matière convient comme aliments, milieux filtrants pour purificateurs d'eau et ainsi de suite.
