The science of making fruits and veggies last longer | Jenny Du

In this TED Talks Daily episode, host Elise Hu introduces a talk by engineer and chemist Jenny Du, who discusses her company's innovative approach to reducing food waste and plastic production by mimicking nature's preservation methods. Du explains how applying a thin layer of plant-based ingredients, similar to a fruit's natural peel, can extend the shelf life and quality of fresh produce without relying on refrigeration, pesticides, waxes, or plastics. She shares the initial success with finger limes and the broader applicability to various fruits and vegetables, highlighting the environmental benefits and potential for a more diverse global food supply. Following the talk, a Q&A session with Lateef Nasser explores the practical aspects, such as the impact on avocado shelf life and the neutral taste of the applied coating.
