Adsorption of minerals on the isolated mantle of Patinopecten yessoensis

The isolated mantle of scallop ( Patinopecten yessoensis ) was shown to adsorb minerals (Zn, Ca, Mg, Fe, Cu, Ni and Co) to more than 1% upon treatment with mineral solution. The amounts of adsorbed Zn, Ca and Mg were 44.3, 47.4 and 15.5 mg/g dry weight, when the mantle was treated with 5% ZnSO₄, CaCl₂ and MgSO₄ solutions at room temperature, respectively. The amounts of adsorbed Zn, Ca and Mg were dependent on the concentration of mineral solution used. This is the first report showing that the isolated mantle adsorbs nutritionally important minerals such as Ca, Mg and Fe. This finding may lead to the development of new mineral-enriched food supplements.
