does anybody know how can i test the amount of Monosodium Glutamate (MSG) in food? And what can I use for it?

Answer 1

MSG is a flavor enhancer. Just little amount of it added will make a difference in the food taste - something savory. Too much of it will not make the taste more better but it will turn out not so good instead.

If you are not yet familiar with its taste, try adding about half teaspoon in the final stage of cooking your pot of stew or soup. You will identify the taste in its taste.

MSG is available at the markets (try in oriental ar Asian store) in different names such as Ajinomoto and Vetsin.

++Ok. I got your point. Determination of MSG amount in food is not an easy procedure. One way that I heard of in testing the presence of monosodium glutamate (L-glutamate) in food is through the so called "liquid chromatographic determination".

Doing "free amino acid" assay could be another way of determination.
