Have you ever scanned a food label and wondered, Is Maltodextrin Monosodium Glutamate? You’re not alone. These two common food additives often cause confusion. While they both frequently appear in processed foods, they are distinctly different substances with unique properties and uses. This definitive guide will clear up the confusion, explaining what each one is, how they’re used, and what you need to know about them.
Maltodextrin vs. MSG: Understanding the Key Differences
At first glance, maltodextrin and monosodium glutamate (MSG) might seem similar—they are both white, powdery additives derived from natural sources. However, their chemical structures and primary functions in food are worlds apart.
What is Maltodextrin?
Maltodextrin is a carbohydrate, typically made from corn, rice, potato starch, or wheat. It is produced through a process of partial hydrolysis, breaking down the starch into shorter chains of sugar molecules. It is technically a complex carbohydrate, but its body processes it very quickly, giving it a high glycemic index.

Common uses of maltodextrin include: As a thickener or filler to increase the volume of processed foods, as a preservative to extend shelf life, and as a cheap sweetener or to improve mouthfeel. You’ll find it in items like canned fruits, sauces, instant puddings, and sports drinks.
What is Monosodium Glutamate (MSG)?
Monosodium glutamate, or MSG, is the sodium salt of glutamic acid, a naturally occurring amino acid. Glutamate is found in many whole foods like tomatoes, cheese, and mushrooms. MSG is used exclusively as a flavor enhancer. It doesn’t have its own distinct taste but amplifies the savory, meaty “umami” flavor in foods.
Common uses of MSG include: Enhancing flavors in soups, broths, savory snacks, frozen meals, and restaurant dishes, particularly in Asian cuisine. It allows manufacturers to use less salt while maintaining a satisfying taste.
Are They Safe? Addressing Common Health Questions
Both additives are “Generally Recognized As Safe” (GRAS) by the U.S. Food and Drug Administration (FDA) and other global regulatory bodies when consumed in typical amounts. However, they are not without controversy.
Some individuals report sensitivity to MSG, with symptoms like headache or flushing, though comprehensive studies have not consistently proven “MSG symptom complex.” Maltodextrin’s main concern is its rapid digestion, causing potential blood sugar spikes, which is a consideration for diabetics. It may also affect gut bacteria balance.
Frequently Asked Questions (FAQ)
Q: Is maltodextrin a form of MSG?
A: No. Maltodextrin is a carbohydrate from starch, while MSG is a sodium salt from an amino acid. They are chemically different.
Q: Which one should I avoid?
A: This depends on your personal health goals. If managing blood sugar, watch for maltodextrin. If sensitive to flavor enhancers, you may choose to limit MSG. Reading labels is key.
Q: Are they derived from gluten?
A> Maltodextrin in the US is usually made from corn and is gluten-free. MSG is also gluten-free. Always check labels for allergen statements.
