分析物意義：常見的天然食品組分，例如在奶酪和番茄中或調(diào)味劑中，如味精 

Megazyme檢測試劑盒優(yōu)點：提供的硫辛酰胺脫氫酶是穩(wěn)定的懸浮液而不是可溶性粉末，從而減少了酶的浪費 

The L-Glutamic Acid test kit is a simple, reliable, rapid and accurate method for the measurement and analysis of L-glutamate (MSG) in foodstuffs.
Suitable for manual, auto-analyser and microplate formats.

Colourimetric method for the determination of L-Glutamic Acid
(Monosodium Glutamate; MSG) in foodstuffs and other materials

Principle:
(beef liver glutamate dehydrogenase)
(1) L-Glutamic acid + NAD+ + H2O ? 2-oxoglutarate + NADH + NH4+

(diaphorase)
(2) INT + NADH + H+ → NAD+ + INT-formazan

	Kit size:  60 assays (manual) / 600 (microplate) 
                                         / 700 (auto-analyser) Method:  Spectrophotometric at 492 nm Reaction time:  ~ 9 min Detection limit:  0.21 mg/L Application examples: Fruit and vegetables (e.g. tomato), processed fruit and vegetables
(e.g. tomato puree / juice, ketchup, soy sauce), condiments, processed
meat products (e.g. extracts, bouillon and sausages), soup, pharmaceuticals
and other materials (e.g. biological cultures, samples, etc.) Method recognition: Methods based on this principle have been accepted by ISO, GOST
and NMKL
