Resumo
The characteristics of the clarified “Cerrado” cashew juice, supplemented with Sacharomyces boulardii and different sweeteners, were evaluated. Eight formulations of clarified cashew juice were prepared with different sugars (sucrose-SCO, fructose-FRU, and xylitol-XIL), artificial sweeteners (stevia-STE, aspartame-ASP, and sucralose-SCA), only yeast (YEA), and control (CON). S. boulardii was added to juice (108 CFU/mL), and then the mixture was stored (7 °C) and evaluated during 28 days for pH, titratable acidity, soluble solids, color, osmolality, probiotic survival, and sensory properties. The juices were classified as very acidic (pH~3.2) and there was decrease in soluble solid content during shelf life (~12°–4° Brix). At 28 days of storage, the cellular viability (S. boulardii) was higher than 7 log CFU/mL for almost all treatments and the juice could be therefore considered a probiotic food. The treatment evaluated showed high vitamin C content (54–71 mg/100 mL), total phenolic compounds (75–105 mg/100 mL), total flavonoids content (average ~71 mg/100 mL), and antioxidant activity (86–88% discoloration by DPPH method). The cashew juice added from different sweeteners is a viable matrix for the probiotic, which contributes to the sensory properties of the beverage. Moreover, the sweeteners showed potential for use in low-calorie functional foods.
