<i>In Vitro</i> Bioaccessibility of Tart Cherry Anthocyanins in a Health Supplement Mix Containing Mineral Clay
Bibliographic record
Abstract
The study reports on the in vitro bioaccessibility of anthocyanins present in tart cherry extracts formulated with a mineral clay to produce a novel natural health product. Results show that tart cherry anthocyanins are stable and bioaccessible after gastric digestion but were largely transformed or degraded (>70%) after duodenal digestion. This contrasted the fact that total antioxidant capacity of tart cherry extract using oxygen radical absorbance capacity assay increased almost two-fold after GI digestion. There was no significant difference between anthocyanin recovery when present the mineral clay formulation, compared to control, thus the presence of the cationic-based mineral clay was not a factor in reducing anthocyanin bioaccessibility, or increasing antioxidant capacity. In vitro digestion of foods or natural health products should be included in protocols that aim to assess overall bioaccessibility and bioactivity of those anthocyanins present in tart cherry. PRACTICAL APPLICATION: This research investigates the impact of having a mineral clay-based matrix on bioaccessiblity of tart cherry anthocyanins. This study describes the anthocyanin composition of tart cherry and the effect of cations present in mineral clay on final total bioavailability following in vitro simulation of human gastrointestinal digestion.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
