Method: Colorimetric, with test strips, 50 - 100 - 200 - 300 - 500 - 700 - 1000 - 2000 mg/L (ascorbic acid), MQuant®
The MQuant® Ascorbic acid test strips are suitable for quickly measuring levels of natural ascorbic acid (vitamin C) in foods such as fruit and vegetable juices, soft drinks, and also to check how much ascorbic acid has been added to certain foods as a preservative or antioxidant. Ascorbic acid reduces yellow molybdophosphoric acid to phosphomolybdenum blue. The ascorbic acid concentration is measured semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. For a quantitative determination of Ascorbic acid please refer to our Reflectoquant® test (116981).
