Degree of Doneness of Cooked Beef Longissimus Muscle Alters Lipid Bioaccessibility
Bibliographic record
Abstract
This study investigated if changes in physical state due to sous-vide cooking significantly alter the lipemic response to food. Canadian AAA boneless beef strip loins containing the longissimus lumborum muscle (n=3) were randomly assigned to different degrees of doneness (DOD: raw/20, 50, 60, 70 and 80°C). Lipid bioaccessibility was assessed utilizing the TIM-1 simulated gastrointestinal tract and changes in network structure were analyzed. The total cumulative free fatty acid (FFA) bioaccessibility (%) shows significant differences (P<0.05) depending on the DOD, with the maximum lipid bioaccessibility occurring in samples cooked to 60°C. Furthermore, the denaturation of actin significantly correlates with the total cumulative FFA bioaccessibility whereby the striploin cooked to 60°C presented the maximum bioaccessibility and digestion rate. This research shows the importance of changes to the structural networks of foods and their ability to alter lipid digestion and can aid in the development of foods that tailor FFA release.

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.
