Resumo
The effects of high-intensity ultrasound (HIUS) processing on chemical composition of inulin-enriched apple juice were evaluated at different specific energy levels (0, 1, 4, 7 and 10 kJ/g). The functional beverage was characterized with respect to fructooligosaccharides (FOS) and total sugars content. In addition, the inulin chemical profile was evaluated. The analysis of sugars and fructo-oligosaccharides in the functional juice was performed by high-performance anion exchange chromatography coupled with pulsed amperometric detection (HPAEC-PAD).
