Reducing the punicalagin content is an effective strategy for eliminating astringency of pomegranate juice. In this study, juice was used as raw material, and tannase applied to convert into ellagic acid gallic acid. The effects concentration, reaction time, temperature on deastringency were evaluated, along with antioxidant physicochemical properties treated results demonstrated that, under optimal conditions (33.9 U/100 mL tannase, 30 °C, 90 min time), decreased by 27.8%, while levels increased 24.2% 32.3%, respectively, effectively reducing juice's astringency. Under these conditions, total phenolic reached 110 mg/100 g, a free radical scavenging capacity 69.8%, significantly enhancing properties. These suggest that treatment enhances polyphenol content, thereby improving its health benefits without compromising product quality.
