Viability dataset on microencapsulated probiotics: Sodium alginate viscosity effect.

ABSTRACT: Probiotics must be delivered alive to exert a positive health effects in site of action. But, they must survive different extreme condition through intestinal tract. Microencapsulation techniques have received considerable attention and facilitate a suitable carrier system to reach the target site. The encapsulation techniques applied to probiotics can be classified into two groups, depending on the method used to form the beads: extrusion (droplet method) and emulsion or two-phase system [1], where extrusion is evolved in the vibration technology and in particular, when the wavelength of an asymmetric disturbance exceeds the jet circumference, the break-up occurs. Droplet size depends on nozzle (jet) diameter, viscosity of fluid, surface tension, jet velocity and frequency of disturbance [2,3]. The data presented in this article evaluated the performance of microencapsulated Lactobacillus casei (probiotic bacteria) using vibration technology and using two kinds of sodium alginate gel matrix (low and medium viscosity) and compare the effect over viability. The best conditions for higher viability of probiotics were at a concentration of sodium alginate (medium viscosity) at 2%, with a nozzle of 450 ?m and a frequency of 1000 Hz. The data are related to the research article entitled "Microencapsulation of probiotics by efficient vibration technology" [3], where Microencapsulator provide by BÜCHI (Encapsulated B-390) was used.
