The stability of the sweetener sucralose in a range of prototype beverages was confirmed. Storage conditions were chosen to encompass the typical shelf life of the products under investigation plus some extreme conditions. The methods developed for the analysis of the beverages used high performance liquid chromatography with refractive index detection. The reproducibility of each method was determined by means of recovery experiments. Stored samples were also subjected to sensory evaluation. Sucralose was stable under all the conditions tested thus demonstrating the potential suitability of this sweetener in soft drinks. Copyright © 1990, Wiley Blackwell. All rights reserved
