Capsules are formed having a liquifield core while avoiding capsule core gelatin by adding drops of a solution of either an anionic polymer composition or a cationic polymer composition to a solution of an ionic polymer of opposite charge. The drops contain an active ingredient such as a cell or microorganism capable of producing a biologically active product or can contain a biological or chemical composition. The interface of the ionic polymers form a permeable membrane surrounding the liquid drops.
将阴离子聚合物组合物或阳离子聚合物组合物溶液滴加到带相反电荷的离子聚合物溶液中,可形成具有液场核心的胶囊,同时避免胶囊核心明胶。 液滴中含有活性成分,如能产生
生物活性产品的细胞或微
生物,或含有
生物或
化学组合物。 离子聚合物的界面在液滴周围形成可渗透的膜。
