MSG

Definition

MSG, or monosodium glutamate, is a common food additive used to enhance the flavor of savory dishes, giving them a rich, umami taste.

Scientific / Technical Definition

Monosodium glutamate (MSG) is the sodium salt of glutamic acid, a naturally occurring non-essential amino acid. It is used extensively in the food industry as a flavor enhancer due to its ability to intensify the savory taste known as 'umami' in foods. Chemically, it is represented as C5H8NO4Na and typically appears as a white crystalline powder.

Benefits

• Enhances flavor in low-sodium foods, allowing for reduced salt intake while maintaining taste.
• May help with appetite control by enhancing the taste of foods, potentially making meals more satisfying.

Examples

• Packaged snacks such as chips and crackers
• Canned soups and sauces
• Instant noodles
• Processed meats and frozen meals

Additional Information

• side effects: Some people report sensitivity to MSG, experiencing symptoms such as headaches, flushing, or sweating, often referred to as the 'Chinese restaurant syndrome.' However, scientific evidence supporting widespread adverse effects is limited.
