Sometimes part of it does, but the full answer is more precise than "maltodextrin equals sugar."
Under 21 CFR 101.9, Added Sugars include free mono- and disaccharides added during processing, sugars packaged as sweeteners, sugars from syrups and honey, and certain sugars from concentrated fruit or vegetable juices. FDA's final Nutrition and Supplement Facts label Q&A then addresses hydrolyzed ingredients directly.
The guidance says maltodextrins are ingredients with a dextrose equivalent below 20 and that different maltodextrins can contain different amounts of mono- and disaccharides. It also says that when an ingredient containing mono- and disaccharides created through controlled hydrolysis, including maltodextrin, is added to a food during processing, those mono- and disaccharides need to be declared as Added Sugars.
For shoppers, that creates a practical three-part check:
| Label area | What it can tell you |
|---|
| Total Carbohydrate | The broader carbohydrate load per serving, including carbohydrate that is not shown as sugar |
| Total Sugars | Mono- and disaccharides present in the finished food |
| Added Sugars | Sugars added directly or contributed by qualifying ingredients and processes, including the mono- and disaccharide portion from some controlled-hydrolysis ingredients |
| Ingredient list | Whether maltodextrin appears at all, and where it sits relative to other ingredients |
This is why a product can deserve a closer carb review even when the front label says "sugar free" or "no added sugar." The legal label may be accurate, but your personal rule may be stricter than the marketing claim.
