Nanotechnology in Food Industry: Current Trends and Future Prospects

K Sunanda | T Praveenanjali

Abstract: Nanotechnology stands as a pivotal advanced technology that drives innovation and sustainable growth across the realms of food, medicine, and agriculture. Within the food sector, nanomaterials wield the potential to revolutionize the production of healthier, safer, and higher - quality functional foods, particularly those prone to perishability or semi - perishability. In comparison to conventional food processing methods, nanotechnologies offer unparalleled advantages, including prolonged shelf life, enhanced food quality, and safeguarding against contamination. This comprehensive review delves into the multifaceted applications of nanotechnologies in the development of functional foods, elucidating current trends and future perspectives. It underscores the pivotal roles of advanced nanomaterials across various facets of the food industry, encompassing processing, packaging, security, and storage. The integration of nanotechnologies in food processing yields tangible improvements in food bioavailability, taste, texture, and consistency. These enhancements are achieved through meticulous modification of particle size, potential cluster formation, and surface charge of food nanomaterials. Moreover, the advent of nanodelivery - mediated nutraceuticals showcases the potential for synergistic action of nanomaterials in fortifying food products and extending their shelf life. Furthermore, the application of nanosensors in smart food packaging emerges as a promising avenue for real - time monitoring of stored food quality. By leveraging nanotechnology - enabled sensors, stakeholders can proactively mitigate risks associated with food spoilage and contamination, thereby ensuring consumer safety and satisfaction. The review also addresses critical considerations regarding the impact of nanomaterials on biological systems. Common methods employed for assessing the safety and efficacy of nanomaterials in food applications are examined, shedding light on the imperative of rigorous evaluation and regulatory oversight.
