|Abstract:||This study evaluated the pH, acidity, soluble solids, color, dietary fiber, sensory acceptance and the viability of Lactobacillus rhamnosus, Lactobacillus plantarum and Lactobacillus acidophilus in mango and carrot mixed juices. In addition, this study verified the resistance of L. plantarum that presented greater viability to the gastrointestinal tract simulated in vitro. Three formulations were elaborated (varying the pulps concentration) and the products were stored at 8 °C for 35 days. No difference was found in the total soluble solids and color of the products during storage time at 8 °C. A reduction in pH and an increase in acidity were observed in all samples during storage, probably due to the fermentative action of probiotics, which negatively influenced acceptance after 35 days of storage. On the other hand, juices with a higher concentration of mango pulp were more accepted and may be a strategy to improve the acceptance of fermented juices. Microorganisms showed greater viability in juices that had higher amount of carrot pulp, probably due to the higher fiber content in these samples. During the 35-day shelf life, all juices with L. plantarum maintained counts above 7 log CFU mL−1 after gastrointestinal conditions simulation. Therefore, mango and carrot mixed juice showed to be as a good vehicle for probiotic bacteria and meets the needs of consumers looking for functional, healthy, non-dairy and low-sugar foods|
