    摘要： A method for preparing amorphous calcium phosphate (ACP) and oral care composition containing ACP prepared by the same are disclosed, wherein the method comprises the following steps: (a) cleaning and pulverizing the oyster shells; (b) sintering the oyster shells to obtain a calcium-containing powder; (c) dissolving the calcium-containing powder in water to obtain a calcium-containing solution; and (d) mixing the calcium-containing solution with a other phosphate-containing solution, to produce amorphous calcium phosphate.The method of the present invention not only can simplify the process and reduce the cost, but also can solve the problem of environment pollution resulting from wasted oyster shells. In addition, the ACP prepared in accordance with the method of the present invention further comprises some trace elements, such as strontium (Sr) and fluoride (F), which can improve dental health.

    摘要： The invention relates to a simple and high yield process for producing a regenerated silk fibroin which does not need dialysis. Particularly, a process of the invention is characterized in that the silk fibroin is precipitated by applying a shear stress and/or changing the solvent power of the fibroin solution. The process of the invention simplifies the process of producing silk fibroin and greatly shortens the process time to 1 to 2 hours, whereas the conventional dialysis process is complex and needs around 2 to 3 days. In addition to reducing the time needed, the process of the invention can increase productivity of silk fibroin by at least 8%.
