| description | In order to investigate the extraction efficiency of flavonoids by octenyl succinic acid-modified starch (OSA-modified starch) with varying molecular weights, the immature fruit of Citrus paradisi 'Changshan Huyou', commonly known as "Quzhiqiao", was used as the extraction target in this research. OSA-modified starch was successfully identified and refined, ensuring its molecular weight was appropriate and extraction was optimized. The experimental findings suggested that a concentration of 20 mg/mL of medium molecular weight gelatinized OSA-modified starch was optimal for extracting flavonoids from "Quzhiqiao" using an ultrasound-assisted method (1,000 W, 40 min). Additionally, the ratio of the mass of "Quzhiqiao" to the volume of gelatinized OSA-modified starch employed in this process was determined to be 15 mg/mL. The findings from the in vitro antioxidant studies indicated significant variations in the antioxidant activities of the extract solutions of OSA-modified starches with varying molecular weights. These differences can potentially be attributed to substantial variations in the extract solutions composition. |
