Optimized Production and Bioactivities of Protein Hydrolysates from Atlantic Salmon Processing Discards
Bibliographic record
Abstract
Enzymatic hydrolysis of Atlantic salmon processing discards, including heads and frames, was carried out using Alcalase, Flavourzyme, and their combination. The degree of hydrolysis varied depending on the enzyme and substrate, ranging from approximately 5% to 15%. Alcalase was more effective than Flavourzyme for the hydrolysis of salmon frames and heads. The results also indicated that 1% enzyme concentrations had slightly higher mean DH than 2%. The bioactivity testing indicated that the head hydrolysates had superior DPPH scavenging activity, while frame hydrolysates demonstrated higher ABTS and hydroxyl radical scavenging activity. The correlation between DH and bioactivities indicated that the degree of hydrolysis did not have any significant effect on the DPPH and hydroxyl radical scavenging activities while demonstrating a significant positive correlation against ABTS scavenging activity.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
