A flexible and simple method for the rapid and reliable measurement of citric acid (citrate) in foods, beverages and other materials. Content: 72 assays per kit

UV-method for the determination of Citric Acid in foods, beverages and other materials Principle: (citrate lyase) (1) Citrate → oxaloacetate + acetate (L-malate dehydrogenase) (2) Oxaloacetate + NADH + H⁺ → L-malate + NAD⁺ (D-lactate dehydrogenase) (3) Pyruvate + NADH + H⁺ → D-lactate + NAD⁺

Kit size: 72 assays (manual) / 720 (microplate) / 840 (auto-analyser)Method: Spectrophotometric at 340 nmReaction time: ~ 5 minDetection limit: 0.921 mg/LApplication examples: Grape juice, wine, beer, fruit juices, soft drinks, tea, dairy products (e.g. cheese), meat, processed meat, vegetable and fruit products, bakery products, paper, pharmaceuticals, cosmetics and other materials (e.g. biological cultures, samples, etc.)Method recognition: Methods based on this principle have been accepted by MEBAK, OIV, EU, ISO2963, AOAC and IFU22(Note: If the enzyme oxaloacetate decarboxylase is present in the sample, some of the oxaloacetate product is converted to pyruvate. Therefore, to ensure citricacid is measured quantitatively, D-lactate dehydrogenase (D-LDH) is employedto efficiently convert any pyruvate produced into D-lactate and NAD⁺).

Advantages
