Article Synopsis
- The study focused on immobilizing alcalase, a protease, onto activated chitosan microbeads using various methods like adsorption, crosslinking, and covalent binding.
- Covalent immobilization proved to be the most effective, achieving the highest enzyme activity and loading when using chitosan beads created by electrostatic extrusion.
- The optimally produced alcalase-chitosan microbeads demonstrated significant effectiveness in hydrolyzing egg white and soy protein, achieving a high degree of hydrolysis after multiple uses in industrial conditions.
In this work chitosan microbeads were prepared by emulsion technique and loaded with thyme polyphenols by diffusion from an external aqueous solution of Thymus serpyllum L. The effects of concentrations of chitosan (1.5-3% (w/v)) and GA (glutaraldehyde) (0.

In batch tests, the influence of solution pH, contact time, initial metal ion concentration and temperature was examined. The sorption was found pH dependent, pH 5.
