EM Quant® Ascorbic Acid Test, Catalog No. 10023Test strips for the detection and semi-quantitative determination of ascorbic acid GeneralThe ascorbic acid test can be used to measure natural ascorbic acid (vitamin C) in foods such as fruit and vegetable juices, soft drinks, beer and wine, and also to check how much ascorbic acid has been added to meat products and other food and drinks as a preservative or antioxidant. Principle of the MethodThe color reaction is based on the reduction of yellow phosphomolybdate complex to molybdenum blue by ascorbic acid. Graduation0 - 50 - 100 - 200 - 300 - 500 - 700 - 1000 - 2000mg/l ascorbic acid Directions
NoteStrongly colored liquids, e.g. red currant juice, obscure the color reaction. Check decoloring agents, if used, to discover whether these oxidize ascorbic acid to dehydroascorbic acid, in which case it no longer shows up in the test. Activated charcoal, in particular, may have this effect. Good results can be achieved with Avicel™ cellulose powder. InterferenceSince the basis of the test is a reduction reaction, reducing agents similar to ascorbic acid may yield "false-positives." Standard (1000mg/l)Dissolve 0.10g of ascorbic acid in 100ml of distilled water |
