Nowadays, the consumption of functional foods, such as plant‐based beverages, is increasing due to their health‐promoting properties. The low extraction yield of nutritional and functional components is considered a major challenge during the production of sorghum‐based beverages (SBB), as well as their sensorial properties. This investigation studied the effects of various treatments (acidic using phosphoric acid, enzymatic using α‐amylase, germination, germination‐acidic, germination‐enzymatic, and acidic‐enzymatic) on the functional, nutritional, and sensorial properties of SBB. The two‐stage acidic‐enzymatic treatment demonstrated the highest extraction yield, dry matter, ash, carbohydrates, and reducing sugar contents, as well as the lowest starch content (p <.05). Furthermore, the highest protein content (0.98%) was achieved by the germination treatments of sorghum grains. While the highest fat content was achieved by the acidic treatment (1.38%), the germination‐acidic treatment exhibited the highest energy value (26.02 kcal/100 mL). Moreover, the total phenolic content of the acidic‐enzymatic treatment (44.56 mg GAE/L) was significantly higher than that of other treatments. However, all treatments demonstrated lower antioxidant properties compared to the control treatment (142.85 mg BHT eq./L). Furthermore, the sensory evaluation of the germination and germination‐enzymatic treatments showed acceptable scores (≥7) for consumers. In conclusion, the results indicated that the two‐stage treatments of sorghum, especially the acidic‐enzymatic treatment, were more effective than single treatments for the extraction of functional and nutritional components during the production of SBB.
