ABSTRACT

This study was conducted to investigate and compare the compositions of two varieties: Tympanotonus fuscatus and Pachymelania aurita of periwinkle in Nigeria. The parameters considered were proximate compositions (moisture, protein, fat, carbohydrate, fibre and ash). The average amount of crude protein was found to be 56.06% and 53.47% for T. fuscatus and P. aurita, respectively whereas the average amounts for carbohydrate and lipid were 11.26% and 6.17% for T. fuscatus and 14.37% and 4.77% for P. aurita, respectively. Also, the ash and fibre values obtained were 15.91% and 10.60% for T. fuscatus and 16.14% and 10.98% for P. aurita. More so, it was observed that the caloric value of T. fuscatus was higher than that of P. aurita. It is worthy of note that the ANOVA carried out on these data reported for the two periwinkle varieties were significant on all the parameters investigated at p
