Method of casein obtaining from skimmilk using oligochitosans
Bibliographic record
Abstract
Abstract The interaction of milk proteins and oligochitosans is based on formation of electrostatic complex between negatively charged casein micelles and positively charged polysaccharide groups. At low concentrations of oligochitosans, partial interaction with milk proteins occurs. Maximum protein coagulation (90 %) is achieved in equivalence zone at the concentration of oligochitosans: 45.3 kDa-0.88×10−4 M; 25.4 kDa-1.57×10−4 M; 7.7 kDa – 5.19×10−4 M; 1.5 kDa-26.67×10−4 M. In these concentrations, taking into account the molecular weight and degree of deacetylation of oligochitosans, the total content of protonated amino groups is equal 2.4×10−4 M. When t protein content in skimmed milk is 3.0 % - 3.2%, oligochitosans of any molecular weight and degree of deacetylation can be used for casein coagulation, important that the final concentration of amino groups should be 2.4×10−4 M. It was determined that the use of the studied samples of oligochitosan allows to obtain coacervate where 1 g of oligochitosan binds 6.0 – 6.2 g of milk proteins.

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.
