(联系我时,请说明是在来宝网上看到的,谢谢!)The L-Malic Acid test kit is suitable for the measurement and analysis of L-malic acid in grapes, grape juice and wine using the MegaQuant? colorimeter (measurement at 505 nm). Suitable for white and red wines at all stages of the winemaking process.
Simple colourimetric method for the determination of L-Malic
Acid in foodstuffs, beverages and other materials
Principle:
(L-malate dehydrogenase)
(1) L-Malic acid + NAD+ ? oxaloacetate + NADH + H+
(glutamate-oxaloacetate transaminase)
(2) Oxaloacetate + L-glutamate → L-aspartate + 2-oxoglutarate
(diaphorase)
(3) INT + NADH + H+ → NAD+ + INT-formazan
