The number of probiotics, declined significantly during the incubation time and
the rate of reduction was significantly greater in the free cells
(P < 0.05). About 3.7e4 log reductionwas observed in viable cells of
co-encapsulated L. casei with prebiotic different chain lengths of
inulin after exposure to in vitro acidic conditions (pH ~1.5) for 2 h, as
compared to a 4.5 log reduction for alginate encapsulated and 6.9
log for free cells (Table 2)
