Product Name: Monosodium Glutamate (MSG)
CAS Number: 142-47-2
Molecular Formula: C5H8NNaO4
Molecular Weight: 169.11 g/mol
Monosodium Glutamate (MSG) is a sodium salt of the common amino acid glutamic acid. It is widely used as a flavor enhancer in food products, giving a savory or umami taste to dishes. MSG is a white crystalline powder that is odorless and soluble in water.
MSG should be used in small quantities, typically ranging from 0.1% to 0.8% of the total weight of the food. It can be added directly to recipes during cooking or at the table as a seasoning.
MSG is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) when used as intended. Some individuals may experience sensitivity to MSG, leading to symptoms like headaches, flushing, or sweating, commonly referred to as "Chinese Restaurant Syndrome." However, extensive scientific research has shown that MSG is safe for the general population when consumed in normal amounts.
