Effect of an Artificial Diet on Lipid, Free Amino Acid, and Carotenoid Composition of Green Sea Urchin Gonads
Bibliographic record
Abstract
Flavor is an important sensory attribute of sea urchin gonads. The flavor of gonads is also affected by dietary factors. Lipid fatty acids and carotenoids play an important role in the development of off-flavors during post-mortem period. In addition, free amino acids serve as a major taste-active component in urchin gonads. Hence, the effect of feeding of urchins initially on a Laminaria kelp followed by a grainbased diet on the total lipids and their fatty acids, free amino acids and carotenoids was evaluated. Eicospentaenoic acid was dominant in the lipids of urchins fed on an algal diet, but linoleic acid became dominant upon feeding on an artificial diet. Glycine was the major free amino acid throughout the feeding period and its contribution decreased with the progression of feeding. Carotenoid content, on the other hand, decreased from 23.2 to 9.2 mg/100 g tissue after feeding on the artificial diet. Thus, the role of flavor components and/or flavor precursors of urchin gonads is confirmed.

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.
