Suman Singh's research focuses on bioactive packaging films

Suman Singh’s work contributes to food safety by developing packaging materials designed to inhibit microbial growth and reduce spoilage. By integrating natural antimicrobial agents into packaging films, the aim is to create safer food packaging capable of extending the shelf life of products and minimising the risk of foodborne illnesses. Her research endeavours align with the broader goal of enhancing food safety and security through innovative packaging solutions.

Her research has focused on developing bioactive packaging films incorporating natural antioxidants and antimicrobials. For instance, she has been working on films with extracts from plants like Murraya Koenigii (curry leaves), which show promising results in extending the shelf life of perishable foods.

Research triumphs

During her tenure as a postdoctoral fellow at Yonsei University, South Korea, Singh’s research primarily focused on active packaging materials, including antimicrobial, scavenger, and temperature-sensitivity materials. Her aim was to ensure the delivery of high-quality, safe, and fresh produce while extending the shelf life of perishable items through innovative packaging solutions. 

Her contributions have been recognised with numerous national and international awards, such as the FSSAI Research Award and a University Gold Medal in the MTech program. Notably, she was honoured with the prestigious INSPIRE Fellowship during her PhD program and received a Young Researcher Award at the IFT annual meeting in Las Vegas, USA.

Authorship shines in scientific journals

Singh has authored over 60 research papers in SCI-indexed journals, contributed to three book chapters, and authored the book titled ‘Food Packaging System.’ She is enthusiastic about advancements in biodegradable and edible packaging materials. The integration of smart packaging, capable of real-time monitoring of food quality, and the utilisation of nanotechnology to enhance packaging materials' barrier properties are her interests.

Sowing seeds of sustainability

Sustainable packaging solutions can significantly reduce the environmental footprint of the food industry. By minimising waste, improving recyclability, and utilising renewable resources, these solutions address concerns about plastic pollution and resource depletion, contributing to a more sustainable future. She recognises the importance of such initiatives in fostering environmental stewardship within the food industry.

From problem to progress

One of the biggest challenges in this field is achieving desired mechanical and barrier properties comparable to conventional plastics. Additionally, the cost of production and scalability pose significant hurdles. Ensuring these materials are safe for food contact is another critical aspect.

Technology and its power

Technology will play a pivotal role in revolutionising food packaging. Innovations such as intelligent packaging systems capable of communicating with consumers regarding the freshness and safety of products, along with advancements in 3D printing for custom packaging solutions, are poised to transform the industry. She recognises the significant potential of these technological advancements in enhancing both the functionality and sustainability of food packaging.

Nurturing future talent

Singh advises students to establish a strong foundation in both food science and material science. Keeping abreast of the latest trends and advancements is crucial for success. Additionally, gaining hands-on experience through internships and research projects can offer valuable insights and practical skills that will benefit students in their future endeavours.

Academic collaborations

Collaborations with industry partners and academic institutions have been instrumental in advancing her research. Working with companies specialising in biodegradable polymers has facilitated the testing and refinement of bio-based packaging materials. Additionally, partnerships with international universities have provided valuable access to cutting-edge technologies and diverse expertise, enriching the scope and impact of her work.

Future plans

In the future, her research direction will concentrate on enhancing the functionality of bio-based packaging materials and investigating new sources of natural compounds for active packaging. Within the broader field, she anticipates a transition towards more personalised packaging solutions and the integration of IoT technologies to further enhance food safety and minimise waste.
