<P>PROBLEM TO BE SOLVED: To provide a calcium component that is less apt to be affected by other food components, to affect other food components, and excels in solubility, and to provide food and drink and a calcium-enriched food additives, each of which contains the calcium component. <P>SOLUTION: The calcium component excels in solubility for calcium of 670 mg/100g or higher and is extracted from plants, such as kale. A method for producing the calcium component comprises adjusting a squeezed solution of plants to a pH of 4.0 with acid, adding pectinase to the solution by subjecting to enzyme reaction and deactivation of the enzyme, followed by filtering of the product. <P>COPYRIGHT: (C)2008,JPO&INPIT |
