Eggshell as Calcium Supplement Tablet

Aastha P. Chakraborty, Madhavi Gaonkar


Hen eggs are very nutritious food items but their shells are discarded as wastes from different sources like hotels, houses etc. In this study these discarded eggshells were collected. They were processed and a powder was obtained in final stage. This eggshell finds applications in many fields due to its rich calcium content and here it was used as a calcium supplement for females. Calcium extracted from different eggshells was characterized by Fourier Transform Infrared spectroscopy (FTIR). The data depicted the percentage of calcium in different eggshells. The purpose of this particular project was to study the use of eggshell in different applications like fertilizer, calcium supplement, etc.
