Research Review


Highly acid-sensitive Bifidobacterium adolescentis (ATCC 15703) cells were entrapped in pea, soy, faba, and lentil protein-alginate capsules and subjected to challenge studies in synthetic gastric juice (SGJ, pH 2.5/37°C) and intestinal fluids (SIF, pH 6.5/37°C). B. adolescentis cells trapped in pea, soy, faba, and lentil protein-alginate capsules showed 1.9, 3.3, 5.1, and 5.5 log reductions in cell numbers, respectively after a 2 h challenge. Release of encapsulated B. adolescentis cells in SIF over 3 h indicated that after the first 10 min, almost all cells were released, regardless of the wall material. Storage of pea protein-based capsules was also tested in commercial orange, pineapple, and white grape juices at 4 and 22°C for a 6-week duration. Encapsulated B. adolescentis cells survived in pineapple and white grape juice, but not in orange juice.
