| The viability of Lactobacillus casei in microencapsulated forms with Alyssum homolocarpum seed mucilage
(AHSM) and inulin, and as free cells (unencapsulated) were conducted in simulated gastrointestinal conditions.
The spray drying method (inlet high-temperature (90–100 °C)) was used for microencapsulation. The mixture of
inulin and AHSM resulted in better survivability after spray drying and 0.174 Log CFU/g and 0.015 Log CFU/g
loss against gastric acidic and bile conditions respectively, and also, drying inlet temperature did not reduce L.
casei survival significantly (P < 0.05). The results showed that AHSM, as a novel gum and inulin, as a prebiotic
ingredient, can provide suitable conditions for the viability of L. casei under spray dryer high thermal condition
and adverse effect of gastric and bile solutions. |
