Seaweed-based coating could keep strawberries fresh for days without refrigeration, study finds

If you’ve ever brought home a carton of fresh strawberries only to find them moldy and destined for the trash a few days later, researchers may have found a simple solution: coating the fruit in a seaweed-based liquid that could keep it fresh without refrigeration.University of British Columbia (UBC) scientists developed the seaweed-derived coating with the goal of extending the shelf life of fresh produce and reducing food waste and reliance on energy-intensive refrigeration."Nearly half of all food produced in Canada is lost or wasted, costing the economy an estimated $58 billion annually," the university reported in a news release on the seaweed-coating breakthrough."Fresh fruits and vegetables are particularly vulnerable to spoilage, losing moisture and becoming susceptible to mold and bacteria during storage and transport."EATING 5 FRUITS AND VEGETABLES A DAY MAY NOT BE ENOUGH FOR HEART HEALTH, STUDY FINDSA seaweed-derived coating could offer a new way to keep fresh produce from spoiling as quickly.
