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

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

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

Kit size:                             50 assays (manual) / 450 (microplate)
                                           / 500 (auto-analyser)
Method:                            Spectrophotometric at 340 nm
Reaction time:                 ~ 10 min
Detection limit:                0.21 mg/L
Application examples:
Wine, beer, 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), egg, egg products (e.g. egg powder), baking additives,
vinegar, fruit and vegetables, processed fruit and vegetables
(e.g. tomatoes), meat products, food additives, feed, paper (and
cardboard), cosmetics, pharmaceuticals and other materials (e.g. biological
cultures, samples, etc.)
