Fermented yellow mombin juice using Lactobacillus acidophilus NRRL B-4495: Chemical composition, bioactive properties and survival in simulated gastrointestinal conditions.

ABSTRACT: The purpose of the present study was to evaluate yellow mombin (Spondias mombin L.) juice as a vehicle for the Lactobacillus acidophilus NRRL B-4495 probiotic. The initial pH and fermentation temperature conditions were optimized by central composite rotational design. The beverage was evaluated for its chemical composition, bioactive properties, microbiological stability, survival in simulated gastrointestinal conditions and sensory analysis. The ideal conditions for probiotic juice production were an initial pH of 6.4 and 16 h of fermentation, with maximum viability of 12.9 ± 0.4 Log CFU/mL. The fermented juice showed a total phenolic concentration of 94.90 ± 7.12 GAE/mL and antioxidant activity, as measured by DPPH (0.31 ± 0.00 μmol TE/mL) and ABTS sequestration (2.59 ± 0.30 μmol TE/mL)
