    A mild chitosan/calcium alginate microencapsulation process, as applied to encapsulation of biological macromolecules such as albumin and insulin, was investigated. The microcapsules were derived by adding dropwise a protein‐containing sodium alginate mixture into a chitosan–CaCl 2 system. The beads containing a high concentration of entrapped bovine serum albumin (BSA) as more than 70% of the initial concentration were achieved via varying chitosan coat.Author: P. R.

    Oral delivery of insulin to the gastrointestinal tract is one of the most challenging issues, because it numerous barriers to overcome in order to create an effective system for insulin delivery. In the present study, insulin-loaded alginate/chitosan blend gel beads were prepared with different mass ratios.Author: Djamel Tahtat, Mohamed Mahlous, Samah Benamer, Assia Nacer Khodja, Habiba Oussedik-Oumehdi, Fatima L...

    The presence of chitosan in the blend beads decreased the cumulative insulin release in gastric media and enhanced behavior of alginate/chitosan beads in intestinal medium due to the crosslinking. The alginate/chitosan beads crosslinked by glutaraldehyde may be considered as potential insulin carriers for oral drug delivery system.Author: Djamel Tahtat, Mohamed Mahlous, Samah Benamer, Assia Nacer Khodja, Habiba Oussedik-Oumehdi, Fatima L...
