More Details
- 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. BioAssay Systems QuantiQuik™ L-Malic Acid 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.
What samples have you tested?
The strips have been tested on red wine, white wine, homogenized whole milk, cultured buttermilk, almond milk, yogurt, beer, apple juice, lemonade, grape juice, orange juice, cranberry juice, lime and lemon juice.My sample turns the strip very dark purple, how can I determine the D-lactate concentration?
Very dark purple indicates that the diluted sample concentration is greater than 500 mg/L. To obtain a more accurate concentration, the sample should be further diluted and retested. For example, if the sample was diluted 5×, try diluting 21×.I don’t have access to a pipetteman. How can I accurately measure out my samples?
We offer exact volume transfer pipettes as an accessory. For samples requiring a 21× dilution, order the 20 µL transfer pipettes (TP20). For samples requiring a 5× dilution, order the 100 µL transfer pipettes (TP100).Can I store unused reagents for future use?
Yes, unused reagents can be stored according to the assay protocol. The strips should be kept in a dry, cool location and protected from light.For more detailed product information and questions, please feel free to Contact Us.
