Effect of fermentation time on the nutritional properties of pea protein‐enriched flour fermented by <i>Aspergillus oryzae</i> and <i>Aspergillus niger</i>
Bibliographic record
Abstract
Abstract Background and objectives The overall goal of this research was to examine the effect of solid‐state fermentation using Aspergillus oryzae and Aspergillus niger over time on the nutritional properties of an air‐classified pea protein‐enriched flour (PPEF). Specifically, changes to levels of enzyme inhibitors, total phenolics, in vitro protein digestibility (IVPD), and protein quality (IVPD‐corrected amino acid score) were assessed. Findings Trypsin and chymotrypsin inhibitors were reduced by 11.6 and 30.4%, and 22.8 and 21.8% for A. niger and A. oryzae, respectively, whereas the total phenolic content increased by 35.3 and 44.7% for A. niger and A. oryzae, respectively. IVPD increased over the fermentation time. However, the overall protein quality as measured by the IVPD‐corrected amino acid score became worse, becoming lowered by 5%–15% after 6 hr. Conclusions SSF improved the digestibility and bioactive compound availability, whereas protein quality was not improved. Significance and novelty Findings indicate that this particular solid‐state fermentation system improved the digestibility of the PPEF.

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.
