A study was conducted to know the nutritive value of Edible part of Periwinkle(Turritelacommunis). The proximate composition of periwinkle in both raw and boiled samples wasinvestigated. The proximate analysis was evaluated using standard analytical procedures. The proximate analysis revealed in raw sample that the moisture content is 15.5, ash content is 16.0%, crude fat is 18.8%, crude Fibre is 0, crude protein is 36.94% , and carbohydrate is 12.76% ; and in boiled sample moisture content is

The minerals present in the raw sample are manganese, magnesium, calcium, lead, iron and zinc. There values in (ppm) are 0. 43, 9.64, 2.62, 9.71, 14.7 and 0.11 respectively while minerals present in boiled sample are manganese, magnesium, calcium, iron and zinc with their values in (ppm) 1.29, 13.07, 1.54, 5.7 and 0.06respectively.It was revealed that the periwinkle is very rich in protein and there is no presence of lead after cooking, which would otherwise make it hazardous to human health. The results of the research have potentials for advancing sustainable nutrition. Further work can be done to further verify how safe the periwinkle is for nutrition.
