A team of scientists has designed a novel clay-based coating that can significantly slow the spoilage of fruits and vegetables. The innovation targets the massive waste of perishable goods during long-distance transport from global growing regions to store shelves.
Each year, millions of tons of imported produce such as avocados from Chile, bananas from Costa Rica, and tomatoes from Spain are lost before reaching consumers. This new material aims to extend shelf life by creating a barrier that inhibits the microbial growth and moisture loss that drive rotting.
The coating is made from a specially engineered clay that can be applied as a thin layer. According to the researchers, the treatment is food-safe and could be a low-cost alternative to current preservation methods like wax coatings or plastic wrap.
If scaled commercially, the technology could dramatically reduce food waste and lower costs for importers and retailers. It also offers a more sustainable option compared to synthetic preservatives or single-use packaging materials.
Further testing is needed to confirm efficacy across different types of produce under real-world shipping conditions. The work was published in a peer-reviewed journal.
