Sorbitol

Sorbitol is a natural sugar alcohol that occurs naturally in some fruits, such as pears, apples, and plums. In the food industry, it is used as a sugar substitute with a lower glycaemic index than regular sugar, making it popular in diabetic diets. It has approximately 60% of the sweetness of sucrose and is added to confectionery, chewing gum, diet products, and baked goods. It also acts as a humectant, helping to keep food moist and soft. Excessive consumption may have laxative effects. On food packaging, it is listed under the code E420.
