    The objective of this study was to prepare and cross-link carrageenan beads that may be used as a controlled release delivery system. The influence of the bulk carrageenan and cross-linker concentrations on the bead size was studied in order to assess the mechanism of cross-linking between epichlorohydrin and the polysaccharide.Author: S. Keppeler, A. Ellis, J.C. Jacquier

    The beads with successful immobilization of β-carotene are easy to be recognize as it turned into transparent orange in color beads compared to the original transparent beads. Higher concentration of genipin cross-linked beads has darker orange color and the beads are more elastic compared to the lower concentration of genipin cross-linked beads.Author: Ida Idayu Muhamad, Lim Shu Fen, Ng Hui Hui, Noor Anis Mustapha

    Jun 30, 2000 · The equilibrium swelling behaviors of covalently cross-linked gellan gels were investigated as a function of electrolyte concentration, pH at various ionic strengths. A marked decrease in the degree of swelling is observed when the gels are exposed to an aqueous salt solution, and to low and high pH. A hysteresis that observed for the gel in aqueous SrCl2 solution may be attributed to strong ...Author: Masahiko Annaka, and Yuko Ogata, Takayuki Nakahira
