Abstract: Prior art processes for producing protein-based capsules (for example, capsules for use in electrophoretic media) tend to be wasteful because they produce many capsules outside the desired size range, which is typically about 20 to 50 µm. Capsule size distribution and yields can be improved by either (a) emulsifying a water-immiscible phase in a preformed coacervate of the protein; or (b) using a limited coalescence process with colloidal alumina as the surface-active particulate material.

Abstract translation: 用于生产基于蛋白质的胶囊（例如，用于电泳介质的胶囊）的现有技术方法往往是浪费的，因为它们在所需尺寸范围外产生许多胶囊，其通常为约20至50μm。 可以通过（a）乳化预先形成的蛋白质凝聚层中的水不混溶相来改善胶囊尺寸分布和产率; 或（b）使用胶体氧化铝作为表面活性颗粒材料的有限聚结方法。
