The objective of this study was to evaluate the impact of the addition of oligofructose or polydextrose (2 g/100 g) and Lacticaseibacillus casei (2 g/L) on the quality parameters of grape juices during storage (7 oC/28 days in polyethylene terephthalate flasks). The addition of probiotics or prebiotics did not alter the physicochemical characteristics, texture properties, and storage stability of the grape juices; however, they changed the color and/or turbidity. Oligofructose and polydextrose did not show a protective effect on the probiotic, but the products showed probiotic viability higher than 106 CFU/mL. The grape juice with oligofructose had similar acceptance to the control juice. The addition of polydextrose or reduced probiotic acceptance in most of the evaluated attributes. All grape juices presented scores higher than 6 on a 9-point hedonic scale and an acceptability index higher than 70%. It is possible to produce potentially synbiotic grape juices with suitable quality parameters, probiotic survival, and sensory acceptance.
