Background One of the many relevant factors that influence mollusc consumption is the quality of its meat. The meat of Tympanotonos fuscatus var radula has been traditionally used as a subsistence food source with high-quality nutritious culinary delicacy. The study assessed the biochemical profile, non-enzymatic antioxidants and functional attributes of T . fuscatus var radula from a brackish Creek in Southwest Nigeria. Results Protein formed the highest percentage both in raw and steamed samples with the mean values of 47.61 g/100 g and 46.04 g/100 g respectively. The total mineral content was higher in raw sample (237.40 mg 100 g −1 ) than in steamed sample (201.05 mg 100 g −1 ), in the decreasing order of phosphorus > sodium > calcium > potassium > magnesium. Raw sample had the highest proportion of energy contribution, which was from protein (PEP = 53.1%), while the least energy contribution was from fat (PEF = 3.1%) in steamed sample. The cholesterol content of raw T. fuscatus var radula was 0.15 ± 0.01 mg/100 g, being reduced by steaming to 0.12 ± 0.02 mg/100 g, while a nonsignificantly lower percentage of oleic was also observed in steamed sample (0.98 ± 0.01%). After steaming, the values of TBA, ascorbic acid and DPPH increased from 0.22 to 1.41 mg/100 g, 15.31 to 20.54 mg/100 g and 65.11 to 84.6%, respectively. Relatively, higher mean values of water absorption capacity (198.13%), oil absorption capacity (292.59%), and foam capacity (6.90%) were recorded in raw sample, while steamed sample was better in foam stability (33.33%) and emulsion stability (51.51%). Conclusions T. fuscatus var radula is a good source of nutrition, rich in protein and because of its good functional physiognomies, the steamed edible part will be highly desirable for preparing complimentary food.
