Plant carotenoids evolution during cultivation, postharvest storage, and food processing: A review
Bibliographic record
Abstract
Carotenoids in nature are predominantly C40 hydrocarbons that may contain oxygenated functional groups. Although they are well-recognized to exhibit key human health benefits, they cannot be synthesized in the human body and must be obtained from the diet. Fruit and vegetables are the primary dietary sources of carotenoids because plants automatically synthesize these compounds to protect cells from oxidative damage that may occur upon photosynthesis due to light. Biosynthesis and accumulation of carotenoids in plants begin during cultivation through postharvest storage. However, these compounds naturally degrade upon plant senescence and also during food processing (e.g., blanching, pasteurization, and drying). In this article, evolution of carotenoids during cultivation, postharvest storage, and food processing is comprehensively reviewed. Appropriate conditions and methods to cultivate, store, and process fruit and vegetables to help retard carotenoid degradation and enhance carotenoid biosynthesis are also reviewed and identified.

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.
