The microstructure of the generated microbeads was studied, as well as their microencapsulation efficiency and release properties. Overall, pectin-based beads performed better than their alginate-based counterparts. This, combined with a greater incorporation of tannins in the feed formulations led to a higher tannin load in the final beads. The best microencapsulation efficiency was given by pectin microbeads loaded with 10% tannin extract (w/w), but the final tannin content could be further increased by adding a 20% (w/w) concentration of the extracts. During a 14-days storage, only a marginal loss of tannins was recorded foCurrent research in food science243-250https://www.ebi.ac.uk/biostudies/studies/S-EPMC8801355biostudies-literatureTannin-rich extracts improve the performance of amidated pectin as an alternative microencapsulation matrix to alginate.PMC8801355Molino SGomez-Mascaraque LGRufian Henares JAfalseTannin-rich extracts improve the performance of amidated pectin as an alternative microencapsulation matrix to alginate.Microencapsulation of tannin extracts through extrusion-gelation method was performed comparing two alternative encapsulation matrices: alginate and amidated pectin.
