Efeito do perolamento na atividade antioxidante e composição fenólica de cevada
Bibliographic record
Abstract
Most whole grains are processed to make acceptable products. Pearling is used to remove the firmly attached hull of barley as well as the germ in order to extend the shelf- life of the grain and the grain products. The aim of this work was to evaluate the antioxidant activity of two varieties of barley (hulled and hull-less) and correlate this activity with the phenolic composition. Barley grains were pearled and the fractions obtained were analyzed in vitro through antioxidant activity (Free Radical DPPH method and ORAC assay) and phenolic acid determination (Folin- Ciocalteau method and HPLC). The antioxidant activity in both methods presented a significant decrease after the first minute of pearling in both methods, and the results were directly correlated with phenolic acid composition and this trend is observed gradually in the samples up to the third minute of pearling. Is thus necessary to optimize barley processing with the objective of reducing the loss of these compounds during processing

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.
