Brief summary
A double-blind randomized controlled trial (RCT) was conducted in current human study. This study aims to investigate the intervention effect of AOB-w on the short-term exposure and toxicokinetics of acrylamide, a dietary hazardous substance generated during heat processing, in Chinese adolescents.
Detailed description
In the morning of test day, participants were served with a meal of potato chips, corresponding to a single oral dose of 12.6 μg/kg b.w. exposure to acrylamide, and an edible capsule, which contains 350 mg AOB-w or the placebo with the same dose. Urine were collected within 48 hours thereafter. The diet was rigorously controlled within 24 hours prior to study till entire study finished. Four mercapturic acid metabolites have been investigated as urinary biomarkers for short-term internal exposure of acrylamide in human
Interventions
Tea polyphenols 0.05g, 0.1g, 0.2g (starches filled up to 0.35g), edible capsule
Water-soluble antioxidant of bamboo leaves 0.35g, edible capsule
Edible starches 0.35g, edible capsule
Potato Chips bought from market, corresponding to acrylamide (12.6μg/kg b.w. )

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of two hemoglobin adducts of acrylamide | baseline, 3 and 10 days | Blood samples were collected in 0, 3, 10days after the intake of potato chips meals. Two hemoglobin adducts (AAVal and GAVal) of acrylamide were detected by UHPLC-MS/MS. |
| Change of four urinary biomarkers of acrylamide | up to 48 hours | Urine was collected prior to the potato chips meal and 48 hours thereafter, up to 10 urine samples for each participants. Urinary biomarkers of acrylamide were detected by UHPLC-MS/MS. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Area under the concentration versus time curve (AUC) Of acrylamide urinary biomarkers | baseline, 2, 4, 6, 8, 10, 14, 24, 36 and 48 hours | Dynamic changes of biomarkers during the specified intervention period, following 10 urine samples in 48 hours thereafter. |
| Maximum Concentration (Cmax) of Acrylamide Urinary Biomarkers | 48 hours | Maximum concentration of urinary biomarkers during the specified period, measured by curve fitting tools of Matlab Software. |
| Time to Peak Concentration (tmax) of Acrylamide Urinary Biomarkers | 48 hours | Time to Peak Concentration (tmax) of Acrylamide Urinary Biomarkers during the specified period, measured by curve fitting tools of Matlab Software. |
