True Olestra is a fat additive and sucralose is an artificial sugar additive
To me - those are ingredients, not additives. The difference between the two is slight but may I can explain this way. If you make a cake - the ingredients are flour, eggs, sucralose, shortening, baking powder and salt. But if you were a manufacture of cakes and you wanted to make sure your cake lasted a long time - you would add a preservative to that mixture. So the preservative is the food additives - not the ingredients themselves. If Olestra and scuralose were additives then ALL ingredients in a recipe would be considered additives. Olestra is used to replace fat, and sucralose is used to replace sugar.
I would say false as the food is modified. But what do I know.I am not taking a food technology or chemistry class.
