The circinal cavities were found in calcium alginate beads and the cylinder holes were observed in zinc alginate beads from the SEM (micrograph),which indicated that the volume of fraction of zinc alginate polymer was relatively bigger and the zinc alginate polymer chain was more rigid than that of calcium alginate .

凝胶的SEM照片可见,海藻酸钙的冷冻干燥颗粒内为较大的圆孔,海藻酸锌凝胶内为较小的长孔,表明海藻酸锌高分子链在凝胶颗粒中的体积分率相对较大同时刚性较强;卵清蛋白从海藻酸凝胶颗粒中释放的试验结果表明,由于上述海藻酸锌凝胶的特性,导致海藻酸锌对卵清蛋白扩散阻滞作用相对较强;根据试验数据计算得卵清蛋白在海藻酸钙、海藻酸锌凝胶颗粒中的扩散系数分别为1。
