商品说明：
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
