Abstract
In the present study, for valuable utilization, longan seed was utilized as a matrix to establish a packaging film with tea polyphenols, and its properties and preservation action were further determined. With addition of tea polyphenols, the elongation at break of longan seed film were improved (from 12.0 to 14.6%). Meanwhile, the thermal stability, antioxidant capability, water vapor permeability (from 2.42 to 1.33 × 10 –10 g·m –1 ·s –1 ·Pa –1 ), and oxygen permeability (from 2.79 to 2.64 × 10 –16 g·m –1 ·s –1 ·Pa –1 ) of longan seed film were ameliorated with tea polyphenols. By using fresh-cut apples as a model, longan seed film with tea polyphenols exhibited significant inhibition on the enzymatic browning of the fresh-cut apples during storage. Furthermore, it inhibited the decrease of total phenol content and increase of soluble solid content of fresh-cut apples. All results suggest that the longan seed film with tea polyphenols shows the potential to protect the freshness of fruits and vegetables in the food industry.

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
