RODRIGUEZ-BARONA, Sneyder; GIRALDO, Gloria I  and  ZULUAGA, Yenni P. Evaluation of the Incorporation of Prebiotic Fiber on the Viability of Lactobacillus casei Impregnated in Matrices of Andean Blackberry (Rubus glaucus). Inf. tecnol. [online]. 2015, vol.26, n.5, pp.25-34. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642015000500005.

This study showed the favorable effect of prebiotic fiber in the survival of Lactobacillus casei of ATCC 393, incorporated in matrices of Andean blackberry by a process of vacuum impregnation and subsequent lyophilization. Blackberry slices were impregnated with isotonic solutions of inulin, fruit - oligosaccharide (FOS) and inulin-FOS control without prebiotic inoculated with 10⁹ UCF / ml of the microorganism. The impregnated samples were lyophilized and stored at ambient conditions for monitoring. Favorable effects were observed for the presence of prebiotics to the viability of the microorganism, allowing its survival for more than 40 days, with higher counts to 106 UCF / g while in the control sample was lower after 25 days. Sensory analysis showed a higher acceptance score greater than 5 on a scale from 1 to 7. The presence of microorganisms embedded in the fruit was evidenced by the observation with scanning electronic microscopy.
