Abstract

A method for extracting condensed calcium powder from salted anchovies. According to one embodiment, the organic fish waste (e.g., salted anchovy) is stirred with warm water at a temperature of 70 to 80.degree. C. in a weight ratio of 5:5. In one embodiment, the mixture is deposited into a centrifuge to separate the solid sediments containing anchovy bones and the water phase containing skin, flesh and oily components of anchovies dissolved therein. In one embodiment, a settling and filtration process is used to separate the solid sediments from liquid sediments. The solid sediments are sterilized with steam at a temperature in the range of 150 to 200.degree. C. for 15 minutes. The sterilized solid sediments are dried to remove moisture. In one embodiment, the sterilized solid sediments are pulverized into powder. Optionally, the pulverized powder may be formed into a tablet form and packaged. Accordingly, highly condensed calcium powder is extracted.
