Advancements and challenges in biomimetic materials for food preservation: A review

The exploration of biomimetic materials within the food industry has seen recent advancements, yet their practical application remains limited, particularly in food preservation. Significant challenges currently persist from the research and development phase to the investigation of practical applications. Therefore, it is imperative to promptly review the existing research, discuss the challenges, and propose constructive suggestions for current scientific trends. This paper initially summarizes naturally occurring superhydrophobic and superhydrophilic organisms, followed by an analysis of the primary obstacles hindering the practical use of these materials. Subsequently, we delve into fresh-keeping materials inspired by plants, insects, shellfish, and fish. Finally, we forecast the trajectory of this field to direct future research, given the extensive potential of biomimetic materials in food preservation. This study aims to effectively guide the research and development of biomimetic materials and their application within the food preservation industry.
