The present study aimed at examining whether the microencapsulation of Lactobacillus acidophilus LA‐5 and Bifidobacterium animalis BB‐12 inside hydrogels could prolong their survival in freeze‐drying conditions, stored at 4℃ and in the gastrointestinal medium. Microencapsulation was performed by emulsion with a syringe, while sodium alginate and high methoxyl pectin were used as a carrier material. A relatively high efficiency of encapsulation was obtained (>92%). Z‐Average and pdI in samples were not significant ( p < .05). In different treatments, changes in the number of bacteria after freeze‐drying, 30 days of storage, and gastrointestinal conditions, compared to each other, were significant ( p < .05). However, the survival rate after a reduction during storage was higher than 10 6 cfu/g, indicating the suitability of the microencapsulation process. The surface of microcapsules observed by a scanning electron microscope ( SEM ) confirmed the success of encapsulation. Finally, a lower decrease in the count of microencapsulated was observed in comparison to the free cells.
