Fortification of flavored waters with fructoligosaccharides

Abstract

The behavior during storage at room temperature of flavored waters fortified with 5 g/L of fructoligosaccharides (FOS), in PET containers, was studied. In the pineapple and orange flavored waters, the FOS concentration at the end of seven months of storage was 87%. However, in the lemon-flavored water, the final FOS content was 45%. According to the results, the coloration of the pineapple and orange flavored waters did not experience any change, in the same way the sensory evaluation of both waters had an excellent rating, the same not happening with the lemon-flavored water, which its rating was decreasing in the storage time until the assessment of good at the end of the study, due to loss of intensity of the smell and taste of lemon. During the seven months of storage, the microbiological quality of all the flavored waters was satisfactory. It is recommended to make an adjustment in the lemon formulation, to achieve a FOS behavior like that obtained in orange and pineapple flavored waters.
