Opis

Opis ogólny

L-malic acid, also known as L-malate, is a dicarboxylic acid present in all living organisms, and it plays a pivotal role in the Calvin and Krebs (Citric Acid Cycle) Cycle. Its quantification holds particular significance in various industries, including winemaking, brewing, baking, and the production of fruit and vegetable goods, cosmetics, and pharmaceuticals. It is recognized as one of the most prevalent fruit acids and typically constitutes the highest acid concentration in wine. L-malic acid, owing to its greater acidity compared to citric acid, is widely employed in the food industry as an acidity regulator, preservative, or flavor enhancer.In winemaking, the microbial conversion of L-malic acid to L-lactic acid is a monitored process, particularly during malolactic fermentation. This transformation leads to an overall reduction in wine acidity, contributing to an enhanced wine flavor. Moreover, L-malic acid serves as a valuable food preservative (E296) and a flavor-enhancing component, often utilized in the formulation of low-calorie beverages.Sigma-Aldrich′s Malic Acid Test strips offer an accurate means to monitor malic acid levels during malolactic fermentation, preventing microbial growth and ensuring wine stability. Furthermore, the assessment of L-malic acid levels in biological samples provides researchers with insights into cellular metabolism and energy production, offering insights into potential alterations in metabolic pathways.

Zastosowanie

The Malic Acid Quick Test Strips are designed for determining Malic Acid levels in the following applications:

• Food and Beverage Testing
• Monitoring malolactic fermentation (MLF) in wine production

Cechy i korzyści

Fast and Sensitive: Offers rapid results with the flexibility to 20 or 100 µL of sample for semi-quantitative measurement between 0-500 mg/L (undiluted) malic acid

Quick Results: Sample treatment and assay can be completed in under 15 minutes, ensuring efficiency

User-Friendly Design: Convenient test strip design eliminates the requirement for a plate or cuvette reader

Przydatność

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

Zasada

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.
