  • Patent number: 6998143
    Abstract: An iron fortification complex which may be used to fortify foods and beverages with iron. The complex is formed of ferric ions and caseinate. The complex is sufficiently stable as to be suitable for use in retorted products. However, despite the stability, the iron in the complexes has substantially the same bioavailability as ferrous sulfate.

  • Patent number: 6994876
    Abstract: An iron-protein hydrolysate complex which may be used to fortify foods and beverages with iron. The complex is formed of ferrous ions chelated to partially hydrolyzed egg white protein. The hydrolyzed egg white protein has a molecular weight in the range of about 500 to about 10,000. The complexes are sufficiently stable as to be suitable for use in sterilized products, such as retorted products. Moreover, despite the stability, the iron in the complexes has substantially the same bioavailability as ferrous sulfate.
