Determination of glucose in wine and fruit juice based on a fibre-optic glucose biosensor and flow-injection analysis

Prediction of Glucose Concentration in a Glucose-Lactose Mixture Based on the Reflective Optical Power at Dual Probe Wavelengths

“…The detection of high concentrations of glucose in complicated mixtures has attracted an abundance of attention in the food, beverage, and fermentation industries, as well as in the treatment of disease in domestic animals, where glucose mostly acts as a vital substance and is present in high concentrations, from 1 to 10 g/dL [1][2][3][4][5][6][7][8]. Schemes employing highly efficient liquid chromatography and glucose oxidase have been used to predict high glucose concentrations in a complex situation [2][3][4][5][6][7][8].…”

“…Schemes employing highly efficient liquid chromatography and glucose oxidase have been used to predict high glucose concentrations in a complex situation [2][3][4][5][6][7][8]. However, most previous approaches were susceptible to several critical disadvantages, including sample destruction, short enzyme lifetime, long measurement time caused by either the catalytic reaction or substance separation process, and high cost resulting from immobilization of the enzyme.…”

Flow Injection Analysis for Amperometric Detection of Glucose with Immobilized Enzyme Reactor

“…Other possibility is spectrophotometrical detection of glucose, by reaction with hydrogen peroxide so colored product may be produced (9,20,27). A few reports have introduced GOD application for determination of glucose in fruit juices using a flow-injection analysis (FIA) system (7,18). This is an automatic system for on-line determination of glucose concentration.…”

Glucose Determination by Biosensors

“…Glucose analysis by optical biosensors was performed with an oxygen optrode with immobilized glucose oxidase. The molecular oxygen consumption was monitored with a fluorescence indicator, decacylene [20]. The chemilumescence of luminol, in the presence of H 2 O 2 generated in the glucose-oxidase cataysed reaction, can be exploited in glucose analysis [1,2].…”
