Ultra-high pressure homogenization does not impair the in vitro digestibility of egg yolk granule proteins
Bibliographic record
Abstract
Egg yolk granule is a promising ingredient in the food industry. Recent studies have shown that ultra-high pressure homogenization (UHPH) improved the techno-functional properties of the granule, but they did not evaluate its impact on digestibility. Consequently, this work aimed to evaluate the impact of UHPH-treatment (300 MPa and 4 passes) on granule digestibility by using a static in vitro digestion method. While UHPH destabilized the high molecular weight granule lipoproteins, the treatment did not affect the in vitro digestibility of egg yolk granule since similar protein/peptide profiles were obtained from gel electrophoresis and RP-HPLC analysis. Moreover, the degree of hydrolysis was similar between control and UHPH-treated granules with values ranging from 11.5 to 25.2% for the gastric and intestinal phases, respectively. Finally, apovitellin 3-4, apovitellenin IV and phosvitin were specifically digested during the gastric and intestinal phases. Consequently, modifications induced by UHPH on egg yolk granule were not correlated with in vitro digestion experiments. Nevertheless, this work represents an interesting added-value to support the development of innovative egg yolk granule-based ingredients for the food industry. • UHPH destabilized yolk granule lipoproteins. • The in vitro digestibility of yolk granule was not affected by UHPH. • Apovitellin 3-4, apovitellenin IV and phosvitin were specifically digested.

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.
