Preparation, pungency, and bioactivity of capsaicin: a review
Bibliographic record
Abstract
Abstract Capsaicin is the main pungent compound in red pepper responsible for its dual attributes of culinary utility and bioactive efficacy. This review aims to systematically review the preparation methods, pungency, and bioactivities of capsaicin. Capsaicin can be extracted by maceration, microwave, near-infrared extraction, supercritical fluid, and ultrasound-assisted extraction methods. Also, it can be synthesised through chemical, biosynthetic, and in vitro cell methods. Capsaicin can elicit a pungent sensation via activation of TRPV1 receptor. Furthermore, it has been reported to display various bioactivities, such as hypoglycaemic, hypolipidemic, analgesic, anti-cancer, anti-inflammatory, and intestinal health-protecting activities via several signalling pathways. Overall, this review can provide a theoretical reference for understanding the preparation, pungent sensation, and bioactivities of capsaicin.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
