General description

Lactic acid, or lactate, is generated by lactic acid dehydrogenase (LDH) under hypoxic or anaerobic conditions. D-lactic acid is produced in only minor quantities in animals and measuring for D-lactic acid in animal samples is a means to determine the presence of bacterial infection. Furthermore, since D-lactic acid is a specific indicator of bacteria fermentation, its measurement can be used to determine the freshness of milk, meat and fruit juices. Elevated levels of D-lactic acid in wine is an indication of lactic acid bacteria contamination.

Application

The D-Lactic Acid Quick Test Strips are designed for determining D-Lactic Acid levels in the following applications:
  • Food and Beverage Testing
  • Bacterial Fermentation Detection
  • Bacterial Contamination in wine production

Features and Benefits

  • Rapid and Versatile: Delivers quick results, offering the flexibility of using either 20 or 100 μL of sample for semi-quantitative measurement across a range of 0-180 mg/L (undiluted) D-lactic acid, meeting diverse testing requirements efficiently.
  • Time-Saving: Enables sample treatment and assay completion in under 15 minutes, ensuring efficient testing without compromising accuracy, saving valuable time for users.
  • User-Friendly Design: Simplifies testing with a convenient test strip design that eliminates the need for a plate or cuvette reader, making the process more accessible and user-friendly for individuals of all skill levels.

Suitability

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

Principle

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