Nearly 60% of harvested fruits and vegetables go to waste, driving an urgent need for innovative solutions to tackle one of the main culprits: mold growth. To pioneer a new nature-based solution, researchers and experts from Chalmers University of Technology, Aalto University, Axfoundation, and RISE are uniting in the cross-disciplinary project YeastGuard. The goal? Develop an innovative living material using yeast to prevent mold, cut food waste and bolster food system resilience.
