Abstract

Ferritins represent a class of iron storage proteins with detoxification functions. The importance of these proteins is reflected by their wide distribution throughout the animal and plant kingdoms. Ferritin has two forms: holo and apo. Holo ferritin can act as an efficient and safe factor for iron supplementation, whereas apo ferritin is able to serve as a promising delivery nanovehicle for nutrients and bioactive compounds. So far, the dual functions of ferritins from animal and plant sources have been extensively studied in several fields, such as food, nutrition, medicine, and materials. This review outlines the structure of animal and plant ferritin, the iron supplementation function of holo ferritin, and the delivery function of apo ferritin. Recent advances in iron supplementation and nutrient encapsulation and delivery are highlighted. Finally, the current challenges and future developments for multifunctional applications of ferritins are discussed.
