They noted that the survivability of the microencapsulated B. longum B6 with gum Arabic, gelatin or soluble starch remained relatively stable while skim milk showed a tendency to decrease. Also they determined that encapsulation with gelatin or soluble starch provides a higher protective effect on the survival of B. longum B6 when exposed to the simulated gastric
solution, pH 2 (Lian et al., 2003).
