Microencapsulação de probióticos por spray drying: avaliação da sobrevivência sob condições gastrointestinais simuladas e da viabilidade sob diferentes temperaturas de armazenamento

Microencapsulation of Probiotic Strains by Lyophilization Is Efficient in Maintaining the Viability of Microorganisms and Modulation of Fecal Microbiota in Cats

“…The commercial probiotic supplement initially contained high concentrations (10 8 CFU/g) of lactobacilli, enterococci, and yeasts, but no viable cells were observed after spray drying. These findings are in contrast with the results of Silva et al [ 18 ], who studied the spray-drying microencapsulation of Bifidobacterium animalis and L. acidophilus and reported that this process did not decrease microbial viability. As noted in our study, Silva et al [ 18 ] also observed that microencapsulation produced highly spherical, well-coated capsules that protected probiotic bacteria from environmental conditions, such as pH, storage, and in vitro simulation of the passage resistance through the gastrointestinal tract.…”

Ananta et al [ 19 ] showed that the higher the drying temperature of L. rhamnosus by spray drying, the lower the survival rate.…”

Inclusion of Probiotics into Fermented Buffalo (Bubalus bubalis) Milk: An Overview of Challenges and Opportunities

“…Several encapsulation techniques have been reported such as emulsification [159], extrusion [160] and spray-drying [161], fluid-bed method [162] and freeze-drying [163]. Selection of the appropriate encapsulation method depends on several factors such as the required size of the capsules in the target product, the viability of the probiotic bacteria under the processing conditions used for the encapsulation, cost of the operation, etc.…”

Encapsulação: alternativa para a aplicação de microrganismos probióticos em alimentos termicamente processados

“…Outros materiais que podem ser utilizados na encapsulação de probióticos, como o carboximetilcelulose também apresentam o problema de gerar cápsulas porosas (Butun et al, 2011). Como alternativa, outros materiais de cápsulas podem ser incluídos como quitosana, trehalose, inulina, leite em pó, maltodextrina, farelo de arroz, entre outros para aumentar a proteção aos probióticos (Cavalheiro et al, 2015;Silva et al, 2015;Chitprasert et al, 2012).…”
