L-Lactic Acid Quick Test Strips

产品说明

一般描述

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.

特点和优势

• 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.

适用性

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

原理

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.
