UConn Innovation: AI-Powered ‘Food Additive Lens’ App Demystifies Grocery Labels

Have you ever stood in a grocery store aisle, staring at a food label, and wondered what those long, chemical-sounding ingredients actually do? For most of us, the gap between scientific terminology and consumer understanding is vast. However, a breakthrough from UConn is changing the game.

Yihang Feng, a brilliant PhD candidate in Nutritional Sciences and a Master’s student in Computer Science at the University of Connecticut (UConn), has developed a cutting-edge solution: the Food Additive Lens app.

What is Food Additive Lens?

Food Additive Lens is a free iPhone application (designed for iPhone 14 and newer) that utilizes artificial intelligence to translate complex ingredient lists into plain, understandable language. By simply scanning a label, users receive science-based explanations about additives in seconds.

“Consumers deserve access to clear, credible information about what’s in their food,” says Feng. “Food Additive Lens makes that information available instantly — right when people need it most, while they’re shopping.”

The Science Behind the AI

Developed within the UConn College of Agriculture, Health and Natural Resources (CAHNR), the app isn’t just a simple scanner. It employs a sophisticated three-agent AI system that performs several critical tasks in real-time:

n
• Food Categorization: The system first identifies the type of food product.
• Additive Identification: It isolates specific additives from the ingredient list.
• Simplified Explanation: It explains the role and purpose of each additive using accessible language.

To ensure absolute accuracy, the AI was trained using high-authority data sources, including over 10,000 foods from the USDA’s Global Branded Food Products Database and more than 4,000 FDA-approved additives sourced from the U.S. Food and Drug Administration (FDA) Code of Federal Regulations.

Bridging the Gap Between Science and Shopping

While technical data on food additives is available in academic journals and regulatory databases, it is rarely accessible to the average shopper. This UConn-led project bridges that gap, empowering consumers to make informed decisions about their health and nutrition on the fly.

The app also caters to health professionals by providing deeper technical and regulatory details, making it a versatile tool for both the general public and medical experts.

The Future of Personalized Nutrition

The journey doesn’t end here. Yi Wang, a researcher who collaborated with Feng at UConn and is now a postdoctoral researcher at the University of Maryland, is taking the lead on future developments. The goal? Personalization.

Future updates aim to customize ingredient information based on an individual’s specific health status or dietary restrictions, providing precise suggestions tailored to the user’s unique biological needs.

This innovation aligns perfectly with CAHNR’s strategic vision of enhancing health and well-being on a local, national, and global scale, proving once again that UConn is at the forefront of merging technology with human health.
