The Claim
The fluorescence intensity of coffee polyphenols interacting with milk proteins is correlated with the proline residue content of the proteins, indicating that proline residues play a key role in determining the binding affinity between these molecules.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When coffee compounds meet milk proteins, the glow they produce gets stronger if the milk proteins have more of a specific building block called proline — so proline seems to help them stick together better.
See the scientific wording
The fluorescence intensity of coffee polyphenols interacting with milk proteins correlates with the proline residue content of the proteins, suggesting proline plays a key role in binding affinity.
What the research says
1 studyStudy: Molecular mechanism of the interactions between coffee polyphenols and milk proteins
The study found that coffee compounds stick better to milk proteins that have more proline, and this sticking makes the coffee glow brighter under light — so yes, proline is key to how they bind.
