Trehalose is a bioprotectant. A natural sugar, synthesized by bacteria, fungi, plants, and some animals, to help them survive in freezing temperatures and when there is a lack of water. It’s used commercially in foods to protect them during storage and transportation, for example, and in medicine to protect donor tissues and organs for transplantation while in transit, and eggs for In vitro fertilization.
