What is trehalulose?
Picture 1. Trehalulose structural formula
- Calories per gram = 4 [8-p.16]
- Sweetness relative to sucrose = 60% 
- Net carbohydrates = 100%
Trehalulose is produced during production of isomaltulose from sucrose .
In the small intestinal lining, the enzyme isomaltase breaks trehalulose to glucose and fructose, which are then absorbed in the small intestine .
Trehalulose and Dental Caries
Trehalulose has a low potency to cause dental caries [1,2,3].
Who can benefit from avoiding trehalulose?
Individuals with glucose-galactose malabsorption  and GLUT-1 deficiency syndrome  can have trouble digesting trehalulose. Individuals with hereditary fructose intolerance (HFI) cannot metabolize fructose, so they should avoid trehalulose, which contains fructose.
Trehalulose and Cooking
- Trehalulose is a reducing sugar .
- Trehalulose is highly soluble in water .
