Starch-based moisture sensor for food packaging

Sustenance sector signal

This starch-based sensor changes color to indicate moisture levels in food packaging. It enables real-time monitoring of spoilage risks without requiring power or complex equipment. By catching moisture shifts early, it potentially reduces food waste costs and environmental impact through targeted packaging interventions.

The technology addresses food waste—a major sustainability challenge—by making moisture tracking accessible at scale. If deployed in food packaging, it could lower waste-related costs for producers and consumers while reducing water and land use from spoiled goods. However, the source confirms this is still in development and provides no details on current testing scale, deployment status, or real-world impact. The source provides only this summary.
