Microencapsulation of Bifidobacterium longum 5^1A cells by spray drying and its incorporation in acerola (Malpighia emarginata) pulp powder

Abstract

Market of functional foods grows intensely, such as of fruit juice containing probiotics. However, the survival of the microorganism can be compromised by the low pH of such matrix, and the way of minimizing this acid stress is the use of microencapsulation techniques such as by spray drying. In this study, three formulations were tested for the encapsulation of Bifidobacterium longum 5 1A , and the viability was evaluated during storage after the atomization process and after addition in acerola pulp powder. All formulations offered equivalent protection of the bifidobacteria just after microencapsulation. When microencapsulated cells were incorporated to acerola pulp powder, a higher protection for B. longum 5 1A viability was observed when cellulose acetate phthalate was used after 30 days of storage both at room temperature and refrigeration. Concluding, acerola pulp matrix can be used as an alternative vehicle for probiotic administration, even when stored at room temperature.

Journey of the Probiotic Bacteria: Survival of the Fittest

“…The results showed that B. brevis cells not only survived as they also grew when in the GIT of children. Costa et al [ 187 ] showed that encapsulated Bifidobacterium longum 5 1A for bacterial protection during atomisation. In addition, the cells were protected from the acidity of acerola pulp.…”
