Signal Response: Decrease
Linear Range: 1.0 to 100 µg of citric acid per assay
Limit of Detection: 0.491 mg/L
Reaction Time (min): ~ 5 min
Application 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 citric acid is measured quantitatively, D-lactate dehydrogenase (D-LDH) is employed to efficiently convert any pyruvate produced into D-lactate and NAD+).

应用实例:葡萄汁、葡萄酒、啤酒、果汁、软饮料、茶、乳制品(如奶酪)、肉类、加工肉类、蔬菜和水果制品、烘焙产品、纸张、药品、化妆品和其他材料(如生物培养物) 、样品等)。
方法识别:基于此原理的方法已被 MEBAK、OIV、EU、ISO2963、AOAC 和 IFU22 接受(注:如果样品中存在草酰乙酸脱羧酶,部分草酰乙酸产物会转化为丙酮酸。因此,要确保定量测量柠檬酸,D-乳酸脱氢酶 (D-LDH) 用于有效地将产生的任何丙酮酸转化为 D-乳酸和 NAD+)。

The Citric Acid test kit is a flexible and simple method for the rapid and reliable measurement and analysis of citric acid (citrate) in foods, beverages and other materials.

Note for Content: 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).


内容注意事项:如果所有体积减半,每个试剂盒的手动测试数量可以翻倍。 使用 MegaQuantTM 波分光光度计 (D-MQWAVE) 可以轻松满足这一要求。
