Trehalose is found naturally in mushrooms, algae, and insects. Trehalose received the GRAS (Generally Recognized As Safe) status from the U.S. Food and Drug Administration as a food additive in 2000. Since that time, trehalose has been utilized in many capacities in food production due to its chemical makeup and properties including taste enhancement, food preservation, and stabilization against heat and cold. Food products that may contain trehalose or are predicted to contain trehalose in the future include: dried foods (cereal, powdered milk, beans), frozen foods, confection (candy, gum, chocolate), confectionary (cake, jam, cream), beverages (coffee, tea, fruit juices), and fermented food (bread, yogurt). Trehalose additionally might be utilized in medical and cosmetic products.
