Assessment Of Mineral Composition Of Molluscan Shells In South-eastern Nigeria

Standard methods of analysis were used to determine the mineral and nutrient content of the molluscan shells. The mean and variance of each nutrient were determined. The shells contained high percentage of calcium of 12.35 to 15.07% (13.90±0,26) sodium 0.10 to 1.55% (0.705±0,16) magnesium 0.10 to 1.02% (0.44±0.009) phosphorus 0.18 to 0.63 (0.35±0.005) potassium 0.003 to 0.021% (0.012±0.002). The molluscan shells also has large proportions of crude protein with values of 1.49-3.76% (2.32±0.22). The ash content was between 86.0 and 96% (90.8±1.12). The fat/oil value was 0.40 to 1.0% (0.65±0.07);…
