To examine the total antioxidant capacity and total polyphenol content of a 70 mL beetroot juice shot before and after simulated gastrointestinal digestion.
Subjected a 70 mL commercial beetroot juice shot to an in vitro digestion model including simulated gastric (GAS) and duodenal (DUO) phases.
Assessed total antioxidant capacity using the ferric reducing antioxidant power (FRAP) assay and total polyphenol content using the Folin-Ciocalteu (FC) assay reported as gallic acid equivalents (GAE).
Total antioxidant capacity increased approximately 3-fold from a baseline of 697.9 ± 1.6 μmol/70 mL to 2361.2 ± 20.9 μmol/70 mL following the gastric phase and remained elevated at 1740.3 ± 21.1 μmol/70 mL following the duodenal phase.
Total polyphenol content increased 5-fold from 68.4 ± 0.3 mg GAE/70 mL baseline to 341.6 ± 4.8 mg GAE/70 mL post-gastric phase, maintaining a 3.3-fold increase at 223.2 ± 5.4 mg GAE/70 mL post-duodenal phase.

No takes yet. Share an insight, caveat, or question.

Implication

In vitro digestion analysis reveals elevated antioxidant and polyphenol release across gastric and duodenal phases, suggesting beetroot shots are convenient sources of bioaccessible nutrients.
