In more drastic
pH (pH 1.2) microencapsulation did not provide any protection to
L. acidophilus (Table 2). After 120 min exposure to simulated gastric
juice at pH 1.2 the viability of free cells as well as encapsulated
(MPPEC, MPPEC+WP and MPPEC+WP /HT) was below the detection
limit (b2 log10 CFU/mL).
