DOIAbstract
Calcium alginate gel beads readily interchange solutes with the bulk solution and water with the surrounding media. The transfer properties are often critical for its use, either for its stability and preservation or textural modulation, or for the convenient treatment of contained tissues for cryopreservation. Chitosan has been evaluated for various uses in food, medical, pharmaceutical, agricultural and chemical industries because of its non-toxic, biocompatible, mucoadhesive, and biodegradable properties. A new approach for chitosan application is analyzed: to both protect against microbial-derived damages and to consider permeability modulation on alginate gel beads employed in cryopreservation. Characterization of combined systems of c...
