Description

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.

Features and Benefits

• Fast and sensitive. Use of 20 or 100 μL sample. Semi-quantitative measurement between 0-180 mg/L (undiluted) D-lactic acid.
• Sample treatment and assay can be performed in under 15 minutes.

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.
