The L-Malic Acid (Analyzer Format) test kit is an analyzer format for the specific measurement and analysis of L-malic acid (L-malate) in beverages and food products. On calibration, the prepared reagent is linear to > 80 micrograms of L-malic acid per mL of assay solution.

 

Advantages

• PVP incorporated to prevent tannin inhibition

• Very stable reagent when prepared for auto-analyzer applications

• Linear calibration (R2 ~ 0.9994) up to 80 μg/mL of L-malic acid in final reaction solution

• Validated by the University of Wine, Suze la Rousse, France

• Very competitive price (cost per mL of reagent)

• Both enzymes supplied as stable suspensions

• Very rapid reaction (~ 3 min)

 

Principle:

(L-malate dehydrogenase)

(1) L-Malic acid + NAD+ ↔ oxaloacetate + NADH + H+

(glutamate-oxaloacetate transaminase)

(2) Oxaloacetate + L-glutamate → L-aspartate + 2-oxoglutarate

 

Kit size: 245.5 mL of prepared reagent (R1 + R2)

Method: Spectrophotometric at 340 nm

Reaction time: ~ 3 min

Detection limit: 20 mg/L (recommended assay)
