Description:
<jats:p>The consumption of functional foods has grown rapidly, especially those with added probiotic bacteria, which are generally found in dairy matrices where their growth is favored; therefore, the application of probiotics in other types of matrices presents challenges related to growth, survival, viability, stability and changes in sensory characteristics during processing and storage. Therefore, the present study aimed to develop a new probiotic snack made from quinoa and added with 0.3% spore-forming lactic acid bacteria. The probiotic was added by spraying, after the extrusion process, together with salt and oil, at 70°C under dry conditions. Once the probiotics were incorporated, bacterial viability, resistance to simulated gastric juice, physicochemical and sensory tests were evaluated during 120 days of storage at room temperature and compared with a control snack without probiotic. Viability assessment was maintained above 106 CFU/g snack. Intestinal tract simulation resistance test showed 70% viability. The physicochemical and sensory properties evaluated had no significant changes during storage time compared to the control. Our results showed that the new snack with probiotic is stable during storage at room temperature and low humidity conditions.</jats:p>
