Mouth phase: Simulated saliva fluid (SSF), containing mucin
and various salts, was prepared according to a previous study
(Sarkar, Goh, & Singh, 2009). A 5 mL-aliquot of the emulsions
were mixed with 5 mL of SSF, so that the final mixture contained
2% (w/w) oil. The pH of the mixture was adjusted to 6.8 and it
was incubated at 37 C for 10 min with continuous agitation at
100 rpm.
