Abstract

The work aims to address the limitation of traditional biomass materials with single functionality in food applications by developing multifunctional biomass-based materials through Janus structural design, offering innovative solutions for the functional upgrading of the food industry. Through literature research, the fundamental concepts and morphological types of Janus materials were reviewed, the potential of constructing Janus structures on biomass-based materials via Pickering emulsion, microfluidic technology, and electrospinning was explored, and their functional mechanisms and performance characteristics in three key application areas of toxin detection, food packaging, and smart indicator labels were analyzed. Biomass-based Janus materials, through structural design and functional integration, retain their inherent green attributes, such as renewability, biodegradability, and environmental friendliness, while simultaneously achieving key functional compatibility like hydrophilic-hydrophobic, adhesive-non-adhesive, and magnetic-fluorescent properties, thereby opening a new pathway for low-carbon transition and high-value development within the food industry. However, current research still faces challenges, including insufficient interfacial stability and relatively high production costs for large-scale manufacturing. Therefore, future studies should focus on an in-depth investigation of Janus interfacial interaction mechanisms and overcome the limitations hindering scalable production to promote the stable application of these materials within complex food systems and contribute to the sustainable development of the food industry.
