General description

L-lactic acid, or L-lactate, is generated by lactate dehydrogenase (LDH) under hypoxic or anaerobic conditions. L-lactic acid is added to many foods and beverages to give it a tart flavor. Increased levels of L-lactic acid in milk, egg, and fruit juices can be an indication of spoilage. In the wine industry, increasing levels of L-lactic acid and the decreasing levels of L-malic acid are monitored (Malolactic fermentation). In this process, the overall acidity of the wine is reduced and can lead to the improvement of the flavor of the wine.

Application

The L-Lactic Acid Quick Test Strips are designed for determining L-Lactic Acid levels in the following applications:
  • Food and Beverage Testing
  • Monitoring malolactic fermentation (MLF) in wine production

Features and Benefits

  • Rapid and Versatile: Provides fast results with the option of using 20 or 100 μL of the sample, enabling semi-quantitative measurement across a range of 0-360 mg/L (undiluted) L-lactic acid, accommodating diverse testing needs efficiently.
  • Time-Saving: Completes sample treatment and assay in under 15 minutes, ensuring quick and efficient testing without compromising accuracy, saving valuable time for users.
  • User-Friendly Design: Convenient test strip design eliminates the need for a plate or cuvette reader, simplifying the testing process and making it more accessible for users of all levels of expertise.

Suitability

This kit is suitable for the detection of L-lactic acid in a variety of food and beverage samples.

Principle

The L-Lactic Acid Quick Test Strips are based on L-lactate dehydrogenase catalyzed oxidation of L-lactate in which the formed NADH reduces a chromogenic reagent. The intensity of product color is directly proportional to L-lactate concentration in the sample.
