What Is Monosodium Glutamate?
Monosodium glutamate, or MSG, is a flavor enhancer that has been around for over a century. It was first discovered in 1908 by Japanese chemist Kikunae Ikeda, who isolated it from seaweed. The name itself gives away its composition—glutamic acid, an amino acid, combined with sodium.
But what exactly is the monosodium glutamate doing in your favorite dishes? In short, it enhances the umami flavor, which is often described as the fifth taste after sweet, sour, salty, and bitter. Umami is that deep, savory, meaty quality that makes food more satisfying and full-bodied.

Glutamate in Nature: The Science Behind the Savory
Glutamate isn't just found in processed foods—it's naturally present in many foods we eat every day. Foods like tomatoes, cheese, mushrooms, and even breast milk contain glutamates that contribute to their rich, savory flavors.
When you add MSG to your cooking, you're essentially amplifying the natural umami that’s already there. This is why a little bit of MSG can make a big difference in soups, stews, sauces, and even grilled meats.
Natural Sources of Glutamate | Examples |
---|---|
Dairy | Cheese, yogurt |
Fruits & Vegetables | Tomatoes, mushrooms, spinach |
Meat & Seafood | Beef, chicken, fish, shellfish |
Processed Foods | Broth, soy sauce, bouillon cubes |
Common Uses of MSG in Cooking
MSG is incredibly versatile and used across many cuisines worldwide. It’s a staple in Asian cooking, especially in Chinese, Japanese, and Korean dishes. But it’s also popular in Western kitchens, where chefs use it to boost the flavor of everything from burgers to pasta sauces.
Here are some common uses:
- Enhancing the taste of soups and broths
- Boosting the flavor of roasted or grilled meats
- Adding depth to stir-fries and noodle dishes
- Improving the richness of vegetable-based dishes
Myths About MSG: Separating Fact from Fiction
Despite its widespread use, MSG has been surrounded by controversy for decades. One of the most common myths is that it causes “Chinese Restaurant Syndrome” or “MSG Symptom Complex,” which includes headaches, flushing, and sweating. However, scientific studies have not confirmed this link.
Another myth is that MSG is unhealthy or dangerous. In reality, when consumed in moderate amounts, it’s considered safe by regulatory agencies like the FDA and WHO. The key is to use it in moderation and be aware of individual sensitivities.
