Silk keeps fruit fresh without refrigeration

Half of the world's fruit and vegetable crops are lost during the food supply chain, due mostly to premature deterioration of these perishable foods, according to the Food and Agriculture Organization of the United Nations. Researchers at Tufts University demonstrated that fruits can stay fresh for more than a week without refrigeration if they are coated in an odorless, biocompatible silk solution so thin as to be virtually invisible. The approach is a promising alternative for preservation of delicate foods using a naturally derived material and a water-based manufacturing process. An article about the research is published in Scientific Reports (News Release Tufts University, 6 May 2016).
