The present invention provides a tiny particle for control-release and method of manufacturing the same. The tiny particle comprises algae extracts and divalent metal ions, and forms a complex by cross-linking. The present invention is able to produce the control release particle that meets user’s needs by controlling cross-linking time. In addition, if a surfactant is added, the time for control release can be increased. Therefore, this is an unexpected result.本發明提供一種控制釋放的微小顆粒及其製造方法。該微小顆粒包含海藻提取物和二價金屬離子,並通過交聯反應形成複合物。本發明能夠通過控制交聯反應時間來製造滿足用戶需求的微小控釋顆粒。此外,如果添加表面活性剂,则可以增加控制释放的时间。因此,这是一个出人意料的效果。300‧‧‧微小顆粒301‧‧‧外殼
