Characterization of a Partially Purified Extract from Flax (<i>Linum</i><i>usitatissimum</i> L.) Seed
Bibliographic record
Abstract
Abstract A water‐soluble partially purified extract from defatted flax seed was obtained and characterized; it contained proteins (828.8 g/Kg), as well as water‐soluble carbohydrates (101.4 g/Kg) and phenolic compounds (22.2 g/Kg), essentially secoisolariciresinol diglucoside (SDG, 18.40 g/Kg) and ferulic acid (1.45 g/Kg) and p–coumaric acid (2.07 mg/kg) mainly in their glycoside forms. Proteins of 23–24 kDa were the main protein fractions found in the extract. In an emulsion model system, the flax extract was able to inhibit the production of oxidation products (conjugated diene, peroxides and aldehydes) as well as the degradation of flax oil carotenoids. The antioxidant effects of the flax extract were concentration dependent. Oxidation kinetics of the emulsion supplemented with 0.10 % flax extract were similar to the oxidation kinetics of the control blank, whereas, oxidation parameters of the emulsion supplemented with 0.48 % (and higher) flax extract were equal to or better than the oxidation parameters obtained with the test control emulsion containing 0.01 % BHT. These results suggested that flax seed phenolic compounds (SDG) and low molecular weight proteins, both found in the studied extract, might have very strong antioxidant properties. This is paper number 1089 of the Canadian Grain Commission.

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.
