Patent number: 6607761Abstract: The present invention relates to color and flavor improvements in iron and zinc supplemented dry beverage powders having fruit and/or botanical flavor. Vitamins such as the B vitamins, vitamin A, vitamin C, and vitamin E can be added to the dry beverage mix. The supplemented dry beverage mix can also contain iodine, niacin and folic acid. In particular, methods for fortifying dry beverage mixes with certain bioavailable zinc and iron compounds without producing reconstituted beverages having undesirable color or flavor are disclosed. Also disclosed are beverages and foods fortified preferably with amino acid chelated iron that do not impart objectionable color due to the inclusion of a ferric ion reducing agent such as ascorbic acid and/or an agent such as citric acid that is capable of preferentially complexing ferric ion in the presence of polyphenols or flavonoids that are typically present in these beverages or foods.Type: GrantFiled: November 28, 2001Date of Patent: August 19, 2003Assignee: The Procter & Gamble Co.Inventors: William John Henry, Xiaobing Xi, Michel Lucien Hubert Lannelongue Favre, Haile Mehansho, Renee Irvine Mellican, Jianjun Li
