Poly‐L‐lactic acid/lead(II) acetate basic colour indicator membrane for visual monitoring in shrimp freshness
Bibliographic record
Abstract
Abstract Seafood products are prone to deterioration and, therefore, require a label that identifies quality with the naked eye. A visual freshness colour indicator membrane incorporated with poly‐L‐lactic acid and lead(II) acetate basic is designed via electrospinning technology for freshness monitoring. The colour indicator membrane had a uniform fibre thickness with an average diameter of 1.54 μm and a large specific surface area. In addition, the colour stability of the membrane did not vary with temperature and humidity. The hydrogen sulfide (H2S) responsivity results showed that the membrane gave a rapid and accurate response to the freshness of shrimp, and the detection limit of H2S is 0.45 ppm. Finally, in application, the colour change of the membrane correlated linearly with the freshness of the shrimp, allowing the quality of the shrimp to be identified with the naked eye. The experimental results showed that poly‐L‐lactic acid/lead(II) acetate basic colour indicator membrane had great potential in the detection of shrimp freshness.

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.
