Recent advances in protein-based nanoparticles and their applications in the delivery of bioactive compounds

The target delivery of sensitive ingredients is affected by various factors including hostile processing, and environmental and storage conditions. These factors are significant challenges in the target delivery and stability of bioactive compounds. However, protein-based nanocarriers have the potential to address these challenges. Protein nanocomposites are of special interest in bioactive compound delivery due to their inexpensive synthesis, size, nontoxic nature, and quick removal from the human body. They can be prepared using several procedures including protein encapsulation, template-induced method, nano-spray drying, emulsion method, nanoprecipitation nano-spraying, crosslinking, adsorption, and desolation. A wide range of protein-based nanoparticles is being used in the delivery of bioactive components. The current review discusses the type of protein nanocarrier, methods for preparation, characterization, and potential applications.
