Effect of tea polyphenols on the dilational rheology of Human Whole Saliva (HWS): Part 1, HWS characterization

- Interfacial properties of human whole saliva (HWS) are studied at the air-water interface.
- Diluted HWS films build an elastic character with time due to adsorption/reorganisation of many salivary proteins.
- As adsorption progresses the film nature changes from a soluble surfactant-like to an insoluble protein-like behaviour.
- The surface dilation response to frequency is interpreted using a general mixed kinetic model.
