An Efficient Procedure for Determining Simple Sugars in Fruit Juices

A fast, simplified procedure for determining simple sugars in fruit juices is described. Sample preparation has been generalized to allow for differences in the sample matrices. The use of an evaporative light scattering detector and a different separation column produces separations of fructose, glucose, sucrose, and maltose in less than three minutes, offering a significant improvement over standard methods. Part of the sample preparation can be automated further by using the programming features of many modern autosamplers.
