Water insoiuble chemical biological agents to be encapsulated are dispersed in an aqueous paste of a starch-containing material alkoxide. Subsequent addition of selected water soluble alkali earth metal cations insolubilize the paste, thereby entrapping the agents in a protective matrix. Encapsulation of biologically active compositions provides a shield against hostile environments, improves safety in handling, and slows the release of such compounds to the surrounding medium. Highly volatile liquids are protected against losses by evaporation. Encapsulation also provides protection against decomposition from exposure to ultraviolet light.
要封装的水溶性化学生物制剂分散在含淀粉的烷氧化物的水性糊状物中,随后加入选定的水溶性碱土金属阳离子,使糊状物不溶解,从而将制剂包裹在保护性基质中。 封装生物活性成分可抵御恶劣环境,提高处理安全性,并减缓此类化合物向周围介质的释放。 高挥发性液体可防止蒸发损失。 封装还可防止紫外线照射引起的分解。
