Background

Lactoferrin (LF) is an iron-binding glycoprotein that exhibits a variety of potentially beneficial biological activities and has favorable safety and biocompatibility characteristics. For these reasons, LF has been widely used as a functional component in the medical, food, and cosmetic industries. Applications of LF-based materials, such as complexes, nanoparticles, hydrogels and emulsions, to encapsulate, protect and deliver bioactive compounds is gaining increasing attention.

Scope and approach

This review highlights the considerable potential of LF-based encapsulation and delivery systems by summarizing research progress on the structure, physicochemical properties, and biological activities of LF. In particular, it highlights advances in utilizing LF-based nanocarriers as natural vehicles for nutraceutical delivery and release, as well as strategies for encapsulating LF as a functional ingredient.

Key findings and conclusions

Functional LF-biopolymer complexes can be formed by heat treatment, covalent conjugation or electrostatic assembly under appropriate fabrication conditions. These complexes have been shown to be highly effective for the oral delivery of nutraceuticals and drugs. LF can also be utilized to fabricate emulsions, nanoparticles, or microgels to improve the stability and bioaccessibility of bioactive components. However, there are still a number of challenges associated with optimizing the performance of LF-based delivery systems so that they can be used in commercial applications.
