ABSTRACT
In this study, we prepared apple vinegar beverage with different acidity levels (low and high, LA and HA, respectively) containing fructooligosaccharide (FOS) or isomaltooligosaccharide (IMO). The changes in their properties and sugar composition during storage (at 40oC for 6 months) with those of the control (sample containing sucrose, SUR) were compared. The reducing sugar content in all samples increased during the storage, except for IMO-LA, and SUR showed the highest values. More organic acids were found in the HA samples than in the LA samples. The browning degree, turbidity, and total phenolic content increased during storage in all samples although IMO-LA showed the least. The IMO amount was maintained in the sample during storage. However, most of the FOS and SUR were degraded into glucose and fructose. In conclusion, the properties of low-acidity beverages could be better maintained with the addition of oligosaccharides compared to SUR, and IMO was more suitable for this purpose than FOS, when considering functionality.
