Abstract
Various fatty acids, tocopherols, carotenoids, and their respective antioxidant contributions in 7 amaranth seed and 11 quinoa seed samples along with a new evaluation method are reported. The lipid yield was 6.98-7.22% in amaranth seeds and 6.03-6.74% in quinoa seeds, with unsaturated fatty acids (UFAs) being the predominant fatty acids, 71.58-72.44% in amaranth seeds and 81.44-84.49% in quinoa seeds, respectively. Carotenoids, mainly lutein and zeaxanthin, are confirmed for the first time in amaranth seeds, while β-carotene is reported first in quinoa seeds. The predominant tocopherols in amaranth seeds are δ- and α-tocopherol, whereas γ- and α-tocopherol are the primary tocopherols in quinoa seeds. UFAs, carotenoids, and tocopherols showed good correlation with antioxidant activity. All of the amaranth seeds demonstrated lower overall lipophilic quality than quinoa seeds, with the AS1 and QS10 cultivars providing the highest scores for amaranth and quinoa seeds, respectively. Results from this study will contribute to developing quinoa seeds and related functional foods with increased benefits.

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 it
