Evaluation of the oxidative stability of Chipotle chili (Capsicum annuum L.) oleoresins in avocado oil
Bibliographic record
Abstract
Capsicum annuum L. (Chipotle chili) is a natural source of bioactive metabolites with antioxidant properties. The objective of this research was to obtain and characterize the oxidative stability under storage of Chipotle chili oleoresins extracted with cold-pressed avocado oil. The most efficient conditions obtained to extract carotenoids and phenolic compounds were at 1:3 ratio (chipotle chili: avocado oil; w:v) at room temperature in darkness during 48 h. At the end of the harshest conditions (45 °C, 30 days), the extracts were stable to lipid oxidation with a final Totox value of 27.34, a carotenoid preservation of 85.6%, antioxidant activity retention of 80.66% and a color change (ΔE) of 1.783. The kinetic constants obtained were higher for peroxide formation than for carotenoid degradation. The oleoresins obtained could be considered an economic and sustainable alternative to extract carotenoids with good oxidation stability that could be used in foodstuffs.

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.
