Researchers Develop Antimicrobial 'Jelly Ice Cubes' for Safer Cold Storage
Researchers at the University of California Davis (UC Davis) have developed a new type of cooling cube that could improve cold storage and the shipment of fresh food without relying on ice or traditional cooling packs, which can carry microbiological and cross-contamination hazards.
The plastic-free "jelly ice cubes" do not melt, are antimicrobial and mold-resistant, are compostable and reusable, and prevent cross-contamination. The cubes comprise more than 90% water and other components to stabilize the structure and are soft to the touch. They change color based on temperature and can be molded into any shape. A patent for the cooling cubes was filed in July.
