Is Maltodextrin Monosodium Glutamate? The Key Differences Explained
When scanning food labels, ingredients like maltodextrin and monosodium glutamate (MSG) can cause confusion. Many people wonder, are they the same thing? The short answer is no. While both are common food additives, they are chemically distinct and serve different purposes in our food. This article will clearly explain the key differences between maltodextrin and MSG.
Chemical Composition and Source
Maltodextrin is a polysaccharide, a carbohydrate made from starch. It’s typically derived from corn, rice, potato, or wheat. It’s a white powder that is easily digestible and provides a mild sweetness or no flavor at all, acting primarily as a thickener, filler, or preservative.
Monosodium Glutamate (MSG) is the sodium salt of glutamic acid, a naturally occurring amino acid. It is a flavor enhancer that intensifies the savory, umami taste in foods. While it can be fermented from starch sources, its function is purely to boost existing flavors.
Primary Functions in Food
Their roles in food manufacturing highlight their differences. Maltodextrin is a functional bulking agent. It improves texture, prevents crystallization, and helps blend ingredients together in products like instant puddings, sauces, and sports drinks.
MSG, on the other hand, has no texture or sweetness. Its sole job is to make savory foods like soups, broths, snacks, and processed meats taste more robust and satisfying by stimulating umami receptors on the tongue.
Common Questions Answered
Are They Artificial?
Both additives are derived from natural sources through processing. Maltodextrin comes from hydrolyzed starch, and MSG is often produced via fermentation, similar to vinegar or yogurt. However, they are considered processed food ingredients.
Which One Should I Avoid?
Concerns about MSG are largely based on anecdotal reports, with extensive research finding it safe for the general population. Maltodextrin has a high glycemic index, which may be a concern for people monitoring blood sugar.

Make Informed Food Choices
Understanding these differences empowers you to make better decisions. Maltodextrin and MSG are not the same. One modifies texture, the other enhances taste. Always check ingredient lists to identify what’s in your food based on your personal dietary needs and preferences.
