Aloe vera jelly dessert supplemented with encapsulated in mucilage and sodium alginate: Characterization of physicochemical, sensory properties and survivability against low pH, salt, heat, and cold storage.

The goal of this research was to assess the free (FLC) and microencapsulated (MLC) survivability using sodium alginate and mucilage (PMM), as a second layer to produce probiotic aloe vera jelly dessert (AVJD). To determine bead characteristics, the aspect ratio of the bead, survival in 72°C, and cold storage were assessed as well as for AVJD, survivability of probiotics in simulated gastrointestinal condition (SGIC), and storage time. The results showed that all the beads are spherical (aspect ratio = 1.12), and under heat stress conditions, MLC showed a higher survival rate (50.15%) compared to FLC (not detected after 5 min). The number of survived probiotics in the MLC sample (8.65 log CFU/mL) was higher than FLC (7.52 log CFU/g) on the 28th day. In AVJD, the MLC survived at a minimum scientific adequate number of probiotics (6.88 log CFU/mL) on the 28th day. In SGIC, the final survival rates of FLC and MLC samples were 14.24% and 71.04%, respectively. These results suggest that using alginate and PMM is a promising method to protect from harsh environmental conditions and in AVJD.
