Abstract
The effect of various shrimp processing procedures on the quality and quantity of extracted chitin from the shells of Northern Species Pandalus borealis was investigated. The shrimp were caught from the Northern Shrimp Fishery in 2001 and processed using two different procedures. The first procedure involved cooking in boiling salt water on board the vessel, then packing on ice until delivery for peeling at an inshore peeling plant. The second procedure involved quick freezing of individual shrimp, followed by delivery for cooking and peeling in an inshore plant. Deproteinization, demineralization, and pigment removal procedures were developed for chitin extraction. The results showed that processing procedures of shrimp can result in a variation in chitin yield of up to 85% and can significantly affect the organic matter and ash contents as well as the mineral profile in the shell waste and extracted chitin. Quick freezing of individual shrimp on board of vessels followed by inshore cooking and peeling results in shell waste that produced a high yield of chitin with superior quality.

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
