Protein/Polysaccharide‐Based Hydrogels Prepared by Vapor‐Induced Phase Separation
Bibliographic record
Abstract
Abstract The preparation of hydrogels via vapor‐induced phase separation (VIPS) has received limited attention. VIPS consists of exposing a solution containing a gelling agent to a vapor that induces gelation via mass transfer at the gas/liquid interface. Using mixtures of gelatin B and xanthan gum exposed to acetic acid vapor, it is demonstrated that VIPS is efficient for the preparation of protein/polysaccharide mixed gels. This method prevents the typical precipitation of protein/polysaccharide complexes observed in the strong electrostatic attraction regime. It significantly extends the pH window associated with gel formation, and yields mechanically stronger gels as compared to other preparation techniques such as using glucono delta‐lactone or the conventional dropwise pH adjustment technique. Finally, VIPS yields gels at very low gelling agent content, and for a variety of other mixed systems, including globular proteins such as bovine serum albumin.

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.
