Resumen
Mango slurries were fermented with 6 different probiotic microorganisms (Lactobacillus plantarum, Streptococcus thermophilus, Lactobacillus casei, Saccharomyces cerevisiae D254, S. cerevisiae DV10, and S. cerevisiae R2) to develop products with higher bioactivity. Changes in pH, reducing sugars, organic acids, and volatile compounds were determined. In addition, total phenolics and antioxidant capacity during fermentation were monitored. Among the strains used, S. cerevisiae D254 exhibited the fastest utilization of sugar in a mango slurry. Different volatile compounds were produced, mainly consisting of fatty acids, alcohols, and esters. S. cerevisiae DV10 produced higher amounts of esters and alcohols. The antioxidant capacity of the mango slurries improved by different degrees after fermentation with the six probiotic microorganisms. Fermentation with L. plantarum obtained the most organic acids as well as total phenolics and exhibited the highest FRAP and CUPRAC values. The results of this study indicated that fermentation with probiotic microorganisms can enhance the health benefits obtained from mango slurries. PRACTICAL APPLICATION: Probiotic-fermented mango slurry is a fermentation product that combines the nutritional value of mango with the health benefits of probiotics. Probiotic fermentation improves the flavor of a mango slurry and increases the availability and variety of mango products that can be appreciated by consumers.; © 2018 Institute of Food Technologists®.
