Ferrichrysin (Fcy), which is produced by Aspergillus oryzae and is present in foods used for human consumption, belongs to a group of hydroxamate siderophore ferric iron chelators. Fcy (100 mg/mL) dissolves completely at both pH 2.0 and 7.0, being very stable at a wide range of pH, high temperatures and pressures, with little reactivity to dietary iron(More)
BACKGROUND Deferriferrichrysin (Dfcy) is a siderophore found in foods fermented by Aspergillus oryzae and is a promising candidate for an antioxidant food additive because of its high binding constant toward iron. However, the Dfcy concentration is typically low in foods and cultures. RESULTS We optimised culture conditions to improve Dfcy production to(More)
