Abstract
Celosia cristata Linn., an underutilized flower, contains betalains. The stability of betalain pigments in complex food systems is a significant challenge. In this study, we investigated the potential of copigmentation using gum arabic (0.33 % to 1 %), pectin (0.33 % to 1 %), whey protein (0.33 % to 1 %), ascorbic acid (0.05 %), and calcium carbonate (0.01 %) on betalain content, color stability, and microbial counts in betalains pigments extracted from Celosia Cristata L. flowers during a 90-day of storage period. A total of seven copigmentation treatments (T1 to T7) and a control (T0) without copigmentation were applied to the betalain pigments. The degradation kinetics of betalain pigments at different temperatures were also investigated. The findings revealed that among all copigmentation treatments, T7 (0.33 % gum Arabic, 0.33 % pectin, 0.33 % whey protein, 0.05 % ascorbic acid, and 0.01 % Ca 2+ ) exhibited the highest stability in terms of betalain content and color degradation. • Celosia cristata Linn. Flower used for extraction of betalains. • Copigment treatment T7 (0.33 % gum Arabic, 0.33 % pectin, 0.33 % whey protein, 0.05 % ascorbic acid, and 0.01 % Ca 2+ ) was found best. • Degradation Kinetics of betalains pigment at 4 °C, 20 °C, and 40 °C during storage were investigated.

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
