L-Lactic Acid (L-Lactate) Assay Kit for the specific measurement and analysis of L-lactic acid (L-lactate) in beverages, meat, dairy and food products.

Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4^oC

 

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.)
Method recognition:     
Methods based on this principle have been accepted by DIN, GOST, 
IDF, EEC, EN, ISO, OIV, IFU, AIJN and MEBAK
