Short-term effects of sweetened acidic beverages consumption on human saliva: Colloidal properties and protein composition
Fig 5
Frequency and dissipation shifts (5th overtone) as a function of time and calculated hydrated mass changes in response to buffer (B), saliva (S), apple juice (J), and saliva-juice mixture (SJ) on hydrophilic gold surfaces.
Adsorption characteristics in apple juice (a) refer to protocol 1 in methods, influence of apple juice on saliva (b) refer to protocol 2 in methods or ex-vivo adsorption measurements (c) refer to protocol 3 in methods. Corresponding viscoelastic changes (-∆D/∆f) are presented in ai, bi and ci and hydrated mass (mg/m²) calculated using 3rd, 5th, 7th and 11th overtones are presented in aii, bii and cii for the respective protocol. Means with error bars representing standard deviations of at least three readings (n = 3 x 1).
