UV-method for the determination of D-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

Kit size:                            50 assays (manual) / 500 (microplate) 
                                         / 450 (auto-analyser)
Method:                            Spectrophotometric at 340 nm
Reaction time:                  ~ 5 min
Detection limit:                 0.21 mg/L
Application examples: 
Wine, soft drinks, milk, dairy products (e.g. cream, milk / whey powder, 
cheese, condensed milk and yogurt), 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,
