The global challenge of food waste has found a potential solution in the form of genetically engineered bananas. These modified fruits, developed by a biotech firm in Norwich, can stay fresh and yellow for up to 12 hours after peeling, significantly reducing spoilage during transportation and storage. This breakthrough is part of an ongoing effort to extend the shelf life of various produce items, aiming to combat the staggering amount of food that goes uneaten worldwide.

Biotechnology is emerging as a powerful tool against food waste, which contributes heavily to greenhouse gas emissions. Bananas, being one of the most consumed crops globally, are particularly vulnerable to rapid spoilage. According to estimates, nearly half of all bananas grown never reach consumers' plates. To address this issue, researchers have identified specific genes responsible for browning and ripening processes, allowing them to develop varieties that resist these changes. For instance, the non-browning banana disables a gene linked to polyphenol oxidase, an enzyme causing discoloration. This approach has also been successful in apples, tomatoes, and mushrooms.

This innovation not only benefits retailers and consumers but also aligns with broader environmental goals. By extending the shelf life of perishable goods, we reduce the need for excessive production and disposal, promoting sustainability. Moreover, similar advancements in other crops like lettuce, apples, and potatoes demonstrate the versatility of gene editing technology. Experts believe that these developments will lead to more resilient and sustainable agricultural practices, ultimately contributing to a healthier planet. The ability to tackle multiple aspects of crop preservation through genetic modifications offers hope for addressing the complex issues facing modern agriculture.
