Interaction between Casein Micelles and Whey Protein/κ-Casein Complexes during Renneting of Heat-Treated Reconstituted Skim Milk Powder and Casein Micelle/Serum Mixtures
Bibliographic record
Abstract
Casein micelles were separated from unheated reconstituted skim milk powder (RSMP) and were resuspended in the serum of RSMP that had been heated, with and without dialysis of this serum against unheated RSMP. Using size-exclusion chromatography, it was found that the soluble complexes of whey protein (WP) with κ-casein in the serum of the heated milk bind progressively to unheated casein micelles during renneting, even prior to the onset of clotting. Similar trends were noted when casein micelles from RSMP heated at pH values of 6.7, 7.1, or 6.3, each with different amounts of WP coating the micelles, were renneted in the presence of soluble WP/κ-casein complexes. No matter what was the initial load of micelle-bound WP complexes, all micelle types were capable of binding additional serum protein complexes during renneting. However, it is not clear that this binding of WP/κ-casein complexes to the micellar surface is a direct cause of the impaired rennet clotting of the RSMP.

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.
