Recent advances in nanomaterials-enabled active food packaging: Nanomaterials synthesis, applications and future prospects

Active food packaging has gained increasing attention due to their potential in extending food shelf life. To improve their performance, nanomaterials have been popularly employed in view of their high aspect ratio and numerous active sites. Here, we mainly focus on nanomaterials-enabled active food packaging and their application to delay food deterioration and extend food shelf life. Different dimensions of nanomaterials, as well as their green synthesis approaches, are reviewed. It is found that plant extracts, agricultural by-products, microbes, and microwave -assisted approaches are commonly used in their green synthesis. Then, recent progress of nanomaterials-enabled active food packaging to delay food deterioration and extend food shelf life is summarized. Furthermore, the concerns and future prospects of nanomaterials-enabled active food packaging are discussed.
