Liquid Glucose is a polysaccharide manufactured through chemical synthesis having chemical formula C6H12O6. A clear, colourless or brown viscous liquid, miscible with water. The substance may partly or totally solidify at room temperature and liquefies again when heated to 50 °C
IDENTIFICATION
A. Dissolve 0.1 g in 2.5 ml of water R and heat with 2.5 ml of cupri-tartaric solution R. A red precipitate is formed.
B. Dip, for 1 s, a suitable stick with a reactive pad containing glucose-oxidase, peroxidase and a hydrogen-donating substance, such as tetramethylbenzidine, in a 5 g/I solution of the substance to be examined. Observe the colour of the reactive pad; within 60 s the colour changes from yellow to green or blue.
C. It is a clear, colourless or brown viscous liquid, miscible with water. The substance may partly or totally solidify at room temperature and liquefies again when heated to 50 °C.
Liquid Glucose is an aqueous solution of nutritive saccharide obtained by starch hydrolysis, by using Corn and Rice as raw material, which is purified and concentrated to required solids. .. Liquid Glucose, Glucose syrup and Corn syrups are synonyms.
