摘要：Egeria radiata and Thais coronata locally called Nkop and Nko nko respectively by the Efik, are widely eaten by Niger Delta Region of Nigeria. After consuming their soft-flesh, the empty shells are constantly thrown away as waste. This research therefore is to analyzed and ascertains the suitability of these shell wastes as raw materials for calcium supplements. Results of analysis show that these shell contain a high percentage (95.54%) of Calcium Oxide (CaO), 2.52% of Magnesium Oxide (MgO) and trace amount of other oxides. Calcium oxide has been a major source of calcium; it concluded that Egeria radiata and Thais coronata shells are suitable source raw materials for the production of calcium supplements by our indigenous food industry.
