Malic Acid Quick Test Strips

产品说明

一般描述

L-malic acid, or L-malate, is a dicarboxylic acid that is made by all living organisms and plays an important role in the Calvin and Krebs Cycle. Malic acid is frequently used in food and beverage industries as an additive in products such as wine, beer, candies, etc. It can be used as an acidity regulator, preservative, or simply added for flavor. In the wine industry, decreasing levels of L-malic acid and increasing levels of L-Lactic Acid are monitored during malolactic fermentation. As L-malic acid is converted to L-lactic acid, the overall acidity of the wine is reduced which 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 0-500 mg/L (undiluted) malic acid.
• Sample treatment and assay can be performed in under 15 minutes.

适用性

Suitable for the detection of malic acid in a variety of food and beverage samples.

原理

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