Abstract： To investigate the mechanism of aflavonoid-based preservative extract from Fubaiju in inhibiting browning of fresh-cut lotus roots，and enhance the storage quality，an experiment was conducted using fresh-cut lotus roots as the experimental material. A preservative agent was formulated by combining 0.15% flavonoid extract from Fubaiju， 0.5% calcium chloride， 0.3% citric acid，and 0.5% ascorbic acid. The effects of treating fresh-cut lotus roots with this preservative agent on browning during storage at 4∘C （204号 for O day，6 days，and 12 days were evaluated. Furthermore， parameters includingthe browning degree， polyphenol oxidase （PPO） activity， peroxidase （POD） activity，and metabolites of fresh-cut lotus roots during storage were analyzed. The results indicated that，compared to the control group，the treatment with the flavonoid extract from Fubaiju effectively reduced the browning degree and inhibited the increase in PPO and POD activities. A comparative analysis of browning metabolites between the Fubaiju flavonoid preservative treatment group and the flavonoid preservative group without Fubaiju revealed opposite trends in products such as DL-Tyrosine， （+） -ar-Turmerone，and Jasmone，which exhibited inhibitory effects on PPO and POD enzymes. Comprehensive analysis demonstrated that the Fubaiju flavonoid extract composite preservative effectively preserves fresh-cut lotus roots by mitigating browning.
