Hypothesis
Triboelectric separation will effectively differentiate protein and starch fractions in wheat flour based on differences in surface charge.
Conclusion
Triboelectric separation can enhance protein enrichment in wheat flour, especially when using smaller particle sizes.
Supporting Evidence
- The benchmark sample achieved a separation efficiency of 47%.
- Reground flour reached a separation efficiency of 41%.
- Flour samples showed a sharp drop in protein capture efficiency to only 6.8%.
Takeaway
This study shows that a special method can help separate proteins from wheat flour, making it better for baking and cooking.
Methodology
The study used triboelectric separation to evaluate protein enrichment in wheat flour and gluten-starch mixtures, analyzing mass yield, protein content, and particle size distribution.
Limitations
The presence of non-protein components like fibers and lipids in flour samples complicated the separation process.
