General description

Method: reflectometric with test strips and reagent 0.25 - 2.50 g/l Reflectoquant®
The Reflectoquant Sucrose test is suitable for determination of sucrose in beverages, e. g. fruit/vegetable juice and refreshment drinks after appropriate sample pretreatment or dilution. Sucrose (saccharose) is cleaved by sucrose phosphorylase into fructose and glucose-1-phosphate. The latter is converted by phosphoglucomutase into glucose-6-phosphate. This is in turn oxidized by NAD under the catalytic effect of glucose-6-phosphate dehydrogenase to gluconate-6-phosphate. In the presence of diaphorase the NADH formed in the process reduces a tetrazolium salt to a blue formazan that is determined reflectometrically on the RQflex. For the determination of only glucose please refer to our MQuant or Reflectoquant Glucose tests.
