Simultaneous Determination of Glucose and Analogous Disaccharides by Dual-Electrode Enzyme Sensor System

  • Xian-En Zhang

Abstract

Glucose and disaccharides, such as maltose, sucrose, and lactose, are found in a wide range of foods and beverages. Determination of these substances is important for at least three reasons: nutritional evaluation of natural foods, quality control of food and beverage production, and bioprocess control when the substances serve as microbial substrates. There are several conventional techniques for determining these substances. One of the most widely used is the Fehling titration method, which measures the total reducing sugar. Others include: the densometer method, which measures the density of a specific sugar in a pure sample; the colorimetric method, which measures individual sugars; and optical rotational analysis, which measures a pure sample.
