| Popis: | s Two potential probiotic yeasts Saccharomyces cerevisiae (strain KTP) and Issatchenkia occidentalis (ApC) were microencapsulated using maltodextrin and sucrose or sorbitol with an aim to improve its effectiveness by spray drying. Commercialized probiotic yeast Saccharomyces cerevisiae var. boulardii (NCDC 363) was used as a reference yeast in the study. The efficiency of the encapsulation was evaluated by yeast viability, and physical parameters such as yield, water activity, particle size and shape of the microcapsule. Furthermore, simulated gastrointestinal juice was used to estimate the protective effect of the matrix in the digestive system. Results indicated that sucrose or sorbitol incorporated maltodextrin microcapsules achieved 35–45% of increment in the viability of yeasts NCDC 363, KTP and ApC than maltodextrin alone encapsulated group. The encapsulated yeast was remarkably improved its growth in simulated gastrointestinal condition (32–64% in gastric and 46–80% in bile juice) as compared to the non-encapsulated yeast. However, we did not find any observable difference in growth among encapsulated groups in the gastrointestinal survival assay. The study provided an evidence for incorporation of sucrose and sorbitol enhance the maltodextrin encapsulation efficiency by spray drying. |
