Fructans, water‐soluble fibre and fermentable sugars in bread and pasta made with ancient and modern wheat
Bibliographic record
Abstract
Summary The aim of this study was to determine wheat constituents in bread and pasta that might result in intestinal gas production. Fructans, water‐soluble arabinoxylans, arabinogalactan proteins and fermentable sugars were followed in bread and pasta made with ancient (Khorasan wheat; emmer) and modern wheats (common wheat; durum). After fermentation for 180 min, 80% of fructans were eliminated and higher levels of fructose than glucose accumulated in bread dough supplemented with sucrose. Whole‐grain Khorasan wheat and emmer flours inhibited yeast fermentative activity. Half of fructans, arabinogalactan proteins and sugars were washed out in cooking water for pasta. Water‐soluble wheat arabinoxylans increased in bread and cooked pasta. With very low levels (0.3–0.8%, dry basis), fructans in cooked pasta and, in particular, long‐fermentation bread prepared with modern or ancient wheat would unlikely act as major gas‐forming triggers of gastrointestinal discomfort associated with noncoeliac gluten sensitivity.

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.
