Eight cereal-based probiotic beverages were produced by inoculating discarded bread flour with a monoculture of Lactobacillus rhamnosus or a co-culture consisting of lactic acid bacteria and Bifidobacterium. Two additional factors, namely, the addition of amylolytic enzymes and matrix desalting, were studied alongside the type of culture. The organic acid content and microbial growth were monitored during fermentation and storage (15 and 21 days). Proximal composition, gamma-aminobutyric acid, and volatile compounds were measured in the final product. Sensory analysis was only conducted on the enzymatically treated samples. The estimated shelf life of the bread beverage was 15 days. The variables studied significantly influenced the amountof organic acids and specific volatile compounds responsible for the aroma of fermented beverages. The beverage produced via co-culturing was preferred by consumers in the sensory test. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2024 The authors Atribución 4.0 Internacional Harina - Análisis Food - Analysis Alimentos - Análisis Food - Sensory evaluation Alimentos - Evaluación sensorial Probiotics Probióticos Lactic acid bacteria Functional beverage Alimentos funcionales Fermented beverages Nutrition Food - Biotechnology Food science Characterization of a fermented beverage from discarded bread flour using two commercial probiotics starters info:eu-repo/semantics/article
