摘要：
The present invention relates to a process for the preparation of a system having good controlled release behaviour. It comprises two water-soluble polymers and a proteinaceous material.
An aqueous two-phase system is formed, wherein the proteinaceous material is comprised in the dispersed phase. The dispersed phase is cross linked.
An aqueous two-phase system is formed, wherein the proteinaceous material is comprised in the dispersed phase. The dispersed phase is cross linked.
