1. What is Monosodium Glutamate (MSG)?

Monosodium glutamate (MSG) is the sodium salt of glutamic acid, a naturally occurring non-essential amino acid. Glutamic acid is present in the human body and many foods we consume daily. MSG is used worldwide as a flavor enhancer, imparting an umami or savory taste to dishes.

1.1. The Science Behind MSG: Glutamate and Umami

Glutamate is a naturally occurring amino acid that plays a vital role in our bodies, functioning as a neurotransmitter and contributing to protein synthesis. According to research from the University of California, Berkeley, in July 2025, glutamate provides crucial support for brain function and metabolism. When glutamate is present in food, it activates specific receptors on our tongues, resulting in the savory taste known as umami. This taste is described as meaty, rich, and savory, enhancing the overall flavor profile of various dishes.

1.2. How MSG is Produced for Culinary Use

MSG is commercially produced through a fermentation process, similar to that used for making vinegar, yogurt, and wine. The process typically involves fermenting carbohydrates like corn, sugar beets, or sugarcane.

Here is a simplified overview of the MSG production process:

1.3. A Brief History of MSG: From Seaweed Broth to Global Flavor Enhancer

The story of MSG began in 1908 when Japanese chemist Dr. Kikunae Ikeda identified glutamate as the source of the savory taste in kombu seaweed broth. He patented a method to produce MSG, and it was commercialized in 1909. Since then, MSG has become a widely used flavor enhancer in various cuisines worldwide.

2. Common Foods That Contain Naturally Occurring MSG

Glutamate, the base of MSG, occurs naturally in many foods. These foods contribute to the umami flavor in our diet.

2.1. Vegetables Rich in Natural Glutamates

Several vegetables are naturally high in glutamates, contributing to their savory flavor profiles.

• Tomatoes: Especially ripe tomatoes, are a significant source of natural glutamate.
• Mushrooms: Certain types of mushrooms, such as shiitake and enoki, contain high levels of glutamate.
• Potatoes: This common food contains glutamate, providing a unique flavor profile.
• Broccoli: It naturally contains glutamate, which enhances its flavor and contributes to the umami taste.

2.2. Cheeses High in Glutamate

Aged cheeses are known for their rich umami flavor, which comes from the breakdown of proteins into free amino acids, including glutamate, during the aging process.

• Parmesan: Parmesan cheese is particularly high in glutamate.
• Roquefort: This blue cheese is another excellent source of naturally occurring glutamate.
• Cheddar: Aged cheddar also contains significant amounts of glutamate.

2.3. Meats and Seafood That Naturally Contain MSG

Meats and seafood also contain natural glutamates, contributing to their savory taste.

• Beef: Beef, especially when aged, contains glutamate.
• Pork: Similar to beef, pork is a natural source of glutamate.
• Seafood: Fish and shellfish, such as tuna and scallops, contain glutamate.

2.4. Other Natural Sources of Glutamate

Besides vegetables, cheeses, meats, and seafood, other foods contain natural glutamate.

• Seaweed: As mentioned earlier, seaweed, especially kombu, is a rich source of glutamate.
• Soy Sauce: This fermented condiment contains high levels of glutamate.
