Encapsulation and characterization of catechin and epicatechin microcapsules using yeast cell biocarriers

In this study, catechin and epicatechin compounds were encapsulated using Saccharomyces cerevisiae yeast cell and fabricated yeast cell microcarriers were subjected to bioactive analysis, conformational and morphological characterization. Encapsulation efficiency values of the yeast cell microcarrier were 24.74 and 31.87% for the epicatechin and catechin loaded yeast cell microcapsules, respectively. Total flavonoid content of the epicatechin and catechin loaded yeast cell microcapsules were determined to be 79.67 and 61.86 mg CE/g while the antiradical activity of the samples was in the range of 4.16-39.24%. FT-IR and XRD spectrum revealed that the catechin and epicatechin were encapsulated by the yeasts cell successfully. For further study, stability of catechins loaded yeast cell microcapsules at different media (in vitro and in situ) could be determined.
