Electrophoretic and functional properties of mustard seed meals and protein concentrates
Bibliographic record
Abstract
Abstract Defatted meals and protein concentrates from five varieties of mustard seeds (four Brassica spp. and one Sinapis alba ) were analyzed for polypeptide composition and functional properties. Nonreducing gel electrophoresis showed that Brassica seeds lacked the 135‐ and 50‐kDa polypeptides that were present in the seeds of the S. alba variety. On the other hand, the 29‐kDa polypeptide found in the Brassica seeds was absent from the seed of the S. alba variety. Under reducing conditions, the 135 kDa was not detected in the S. alba variety and the intensity of the 50‐kDa polypeptide was severely reduced; in contrast, the intensity of the 29‐kDa polypeptide in the Brassica seeds was not affected. Meals from yellow seeds had significantly higher ( P ≤0.05) protein contents than meals from the brown seeds. The emulsifying activity indexes (EAI) of meals and protein concentrates from the Brassica seeds were significantly higher ( P ≤0.05) than those obtained for similar products from S. alba sees. It was concluded that the disulfide‐bonded 50‐ and 135‐kDa polypeptides may have contributed to increased rigidity of S. alba meal proteins, which resulted in poor EAI when compared to the Brassica meals, which do not contain these polypeptides.

How this classification was reachedexpand
Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
