Maltodextrins in icing recipe?
What would be the purpose of the maltodextrins content in an icing recipe?
The entire recipe is as follows: natural yogurt [whey solids, yogurt powder (milk and yogurt culture)], cornstarch, maltodextrins, peanut butter powder, guar gum.
Yes, it is missing powdered sugar. It's a "royal icing" recipe that purposely isn't sweet. For dog treats, specifically.
Are the maltodextrins to add sweetness or is there another purpose?
