what is MSG and in which it present how it work
Answers
Monosodium glutamate (MSG, also known as sodium glutamate) is the sodium salt of glutamic acid, one of the most abundant naturally occurring non-essential amino acids.[2] Glutamic acid is found naturally in tomatoes, grapes, cheese, mushrooms and other foods
Umami Taste
Monosodium glutamate (MSG) and certain other amino acids, especially when paired with the nucleotide 5′ inosine monophosphate or 5′ guanine monophosphate, elicit a taste termed umami, now recognized as a fifth taste quality independent of sweet, sour, salty, or bitter. The human detection threshold for MSG is 0.7–3 mmol−1. Umami is a preferred taste, and MSG is a common food additive for animal and human consumption. MSG occurs naturally in many foods and is particularly abundant in protein-rich foods, notably cheeses and meats. There are multiple molecular receptor mechanisms for detecting sodium glutamate which will be described below.
