UV-method for the determination of D-/L-Lactic Acid in 
foodstuffs, beverages and other materials

Principle:
                        (D-lactate dehydrogenase)
(1) D-Lactic acid + NAD+ ↔ pyruvate + NADH + H+

                      (glutamate-pyruvate transaminase)
(2) Pyruvate + D-glutamate → D-alanine + 2-oxoglutarate

                     (L-lactate dehydrogenase)
(3) L-Lactic acid + NAD+  pyruvate + NADH + H+

Kit size:                           * 50 assays of each

The number of manual tests per kit can be doubled if all volumes are halved. 
This can be readily accommodated using the MegaQuantTM 
Wave
Spectrophotometer (D-MQWAVE).
 

Method:                           Spectrophotometric at 340 nm
Reaction time:                ~ 10 min (L-lactic acid) and ~ 5 min (D-lactic acid)
Detection limit:               0.21 mg/L
Application examples:
Wine, soft drinks, milk, dairy products, foods containing milk (e.g. dietetic
foods, bakery products, baby food, chocolate, sweets and ice-cream),
vinegar, fruit and vegetables, processed fruit and vegetables, meat
products, food additives, paper (and cardboard), cosmetics, pharmaceuticals
and other materials (e.g. biological cultures, samples, etc.)
Method recognition:    
Methods based on this principle have been accepted by DIN, GOST,
IDF, EEC, EN, ISO, OIV, IFU, AIJN and MEBAK

Advantages

  • Rapid total analysis time (concurrent / flexible D and L-lactic acid reaction format) 
  • D-lactate dehydrogenase reaction very rapid with most samples (~ 5 min) 
  • Very competitive price (cost per test) 
  • All reagents stable for > 2 years after preparation 
  • Mega-Calc™ software tool is available from our website for hassle-free raw data processing 
  • Standard included 
  • Extended cofactors stability
