3.1 Ex-vivo Evaluation of the Mucoadhesiveness of Synbiotics Mucoadhesive properties prolong the retention time of the bead’s dose in the targeted site the colon [23]‚ [50].

The beads remain longer in contact with colonic mucosa when they have more mucoadhesive property.

the power of the tests that have appeared in the literature as well as tests motivated by the work of Larkey‚ Smith‚ and Kadane (LSK). Three test statistics for the null hypothesis of Bernoulli trials have been considered in the literature; one of these‚ the runs test‚ is effective at detecting one-step autocorrelation‚ but poor at detecting nonstationariy.
