Microencapsulation of LA-5 and BB-12 in pectin and sodium alginate: A comparative study on viability, stability, and structure.

The present study aimed at examining whether the microencapsulation of LA-5 and 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%).
