Researchers in Japan develop sustainable plastic alternative from pumpkin peels
A research team from Kyushu University in Japan has successfully developed an innovative and sustainable food packaging material made from pumpkin peels, aimed at extending the shelf life of fresh produce and reducing spoilage during shipping and storage, thereby directly contributing to a reduction in reliance on traditional environmentally harmful plastics. The university explained on its official website that the scientists utilized pumpkin peels, which account for about 10% of the fruit's total weight and are typically discarded as waste, converting them into fine nanoparticles using advanced techniques including pressing, cooling, and drying. These were subsequently integrated with gelatin and modified cellulose to produce a highly effective biodegradable packaging film. The new material demonstrated outstanding capabilities in inhibiting bacterial growth, blocking ultraviolet rays, and preventing moisture leakage. Practical tests conducted on cherry tomatoes showed that this film outperformed plastic packaging in preventing weight loss and preserving freshness and natural texture over extended periods. The scientific team confirmed that the developed film is completely safe, non-toxic, and suitable for food contact, as well as easy to remove. This represents a promising step towards recycling agricultural waste and employing it in innovative environmental solutions, particularly given current challenges in supply chains due to significant spoilage of vegetables and fruits before reaching consumers. The researchers are currently working to enhance the film's efficiency by adding natural antifungal compounds while focusing on reducing production costs to expand its commercial applications in the future.
