The internal aqueous phase gelation improves the viability of probiotic cells in a double water/oil/water emulsion system

This research studied the viability of probiotic bacterium Lactobacillus plantarum (L. plantarum) encapsulated in internal aqueous phase (W1) a water-in-oil-in-water (W1/O/W2) emulsion system, with help gelation and different gelling agents. Additionally, physicochemical, rheological, microstructural properties fabricated systems were assessed over time under effect W1 gelation. The average droplet size zeta potential control system using gelatin, alginate, tragacanth gum, carrageenan 14.7, 12.0, 5.1, 6.4, 7.3 μm − 21.1, −34.1, −46.2, −38.3, −34.7 mV, respectively. results showed significant increase physical stability encapsulation efficiency L. after significantly increased bacteria against heat acidic pH, gum being best agent for increasing (28.05% 16.74%, respectively). Apparent viscosity rheological emulsions gelation, particularly those jellified alginate. Overall, W1/O/W2 emulsion, followed by as agent, could both this bacteria.
