[1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]

The International Commission for Uniform Methods of Sugar Analysis (ICUMSA) is an international standards body, founded in 1897, [1] [2] that publishes detailed laboratory procedures for the analysis of sugar. The ICUMSA Methods Book [3] contains detailed instructions for analyzing raw, cane, white, beet, molasses, plantation white and ...
All monosaccharide ketoses are reducing sugars, because they can tautomerize into aldoses via an enediol intermediate, and the resulting aldehyde group can be oxidised, for example in the Tollens' test or Benedict's test. [3] Ketoses that are bound into glycosides, for example in the case of the fructose moiety of sucrose, are nonreducing ...

To perform the OF-glucose test, two tubes of OF-glucose medium are inoculated with the test organism. A layer of mineral oil is added to the top of the deep in one of the tubes to create anaerobic conditions. Oil is not added to the other tube to allow for aerobic conditions. The tubes are then incubated for 24–48 hours.
