Chennai Students Win Gold at International Biotechnology Competition with Sodium-Reducing Innovation

Chennai, November 9, 2025 – A team of biotechnology students from Rajalakshmi Engineering College (REC) in Chennai have clinched a gold medal and the coveted Best Project Award in the Food and Nutrition category at the prestigious International Genetically Engineered Machine (iGEM) 2025 competition held in Paris.

The iGEM competition, which drew 421 teams from 40 countries, challenges students to utilize synthetic biology to address pressing real-world issues. The REC team’s winning project, dubbed “SaltEnPep,” impressed judges with its innovative approach to reducing sodium content in food.

“SaltEnPep” employs synthetic biology to produce peptides that amplify the perception of saltiness, allowing food manufacturers to significantly lower sodium levels without compromising the desired flavor profile. This breakthrough could have a major impact on public health by helping to combat the negative effects of excessive sodium consumption.

“We are incredibly proud of our students and their achievement,” said Thangam Meganathan, Chairperson of Rajalakshmi Institutions. Abhay Meganathan, Vice Chairman, echoed this sentiment, congratulating the team on their ingenuity and dedication.

The accomplishment underscores the growing strength of Indian institutions in the field of biotechnology and their commitment to developing innovative solutions for global challenges.
