A simple, reliable, rapid and accurate method for the determination ofL-Gluta mate (MSG) in foodstuffs.

INTRODUCTION:

L-Glutamic acid (L-Gluta mate), one of the 20 common amino acids,

occurs naturally in foods such as cheese, milk, meat, fish, corn,

tomatoes, mushrooms, soybean and sugar beet. In its free form,

L-glutamic acid is the major fl***our enhancing component of foods

with a meaty/s***oury taste. The role played by L-glutamic acid in

the palatability of foods is exploited by either traditional cooking

methods that release free L-glutamic acid, or by supplementation

with monosodium Gluta mate (MSG). Excessive use of MSG as a

food additive (E621) in processed foods results in the symptoms of

“Chinese Restaurant Syndrome” (CRS), where palpitati***, severe

headaches, nausea, wheezing and increased body temperature are

thought to result from the neuro-excitory properties of free

L-glutamic acid. ***et of CRS is fast, only 30-60 min after ingestion,

and symptoms generally subside after approximately 2-3 hours.

Around 15% of Americans are sensitive to MSG.
