摘要： The flavor quality of brown yogurt is affected by the different fermentation methods. In this study, we investigated the effects of probiotics (Lactiplantibacillus plantarum S58), prebiotics (oat (3-glucan), and synbiotics (Lactiplantibacillus plantarum S58 combined with oat (3-glucan) on physicochemical properties, consumer acceptance, flavor substances, and metabolites of brown yogurt. The results showed that the addition of probiotics and synbiotics significantly shortened the curdling time of brown yogurt (30 min and 40 min, respectively), and synbiotics improved the physicochemical properties and flavor components of the yogurt. Compared with the control group, the volatile flavor substances in the synbiotic yogurt, such as acetophenone, 2-decanone, and octanoic acid, were significantly increased. Sensory analysis of 111 consumers showed that the sample of synbiotic brown yogurt was highly accepted and close to the ideal point. Synbiotic fermentation alters the metabolic profile of yogurt, increasing the levels of beneficial metabolites and reducing harmful metabolites. In conclusion, synbiotic brown yogurt achieved the highest quality. This study provides a theoretical basis and data support for the development of brown yogurt with high probiotic activity and a unique flavor.
