Abstract

fetched live from OpenAlex

This is the first report in which barley protein nanoparticles were prepared with the aim of developing a delivery system for lipophilic bioactive compounds at ambient temperature using high pressure homogenization. No organic solvents or crosslinking reagents were involved in the nanoparticle preparation. Effects of processing conditions and formulae on particle size and size distribution were investigated. Optimal nanoparticles with regular spherical shape, small size (90-150 nm) and narrow size distribution (PDI < 0.3) could be achieved at a protein weight concentration of up to 5% when the oil/protein ratio was maintained within a range of 1 to 1.5. These nanoparticles exhibited high zeta-potential (about -35 mV), high payload (51.4-54.5%) and good stability without the use of surfactants. As shown by the release test, though the bulk protein matrices of nanoparticles were degraded in the simulated gastric tract, even smaller nanoparticles were released and bioactive compounds were protected by a layer of barley protein. Then, complete release occurred in the simulated intestinal environments due to pancreatin degradation. In vitro studies showed that barley protein nanoparticles are relatively safe and could be internalized by Caco-2 cells and accumulated in the cytoplasm.

Teacher imitation

Not 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.
