Description: The aim of this study was to determine the effect of moisture content on nutritional and anti-nutritional compositions of mucuna seed. The mature seed samples were used for proximate analysis, mineral composition, anti-nutrient, anti-oxidant and physiochemical properties of Mucuna seed at four moisture content levels. The Association of Official Analytical Chemist (AOAC,2002) was used to determine the proximate analysis, while Association of Official Analytical Chemist (AOAC,1984) was used to determine the anti-nutrient, anti-oxidant activity for 1,1-diphenyl-2-picryllydrazyl (DPPH) was estimated according to Baraca,2003, ferric ion reducing anti-oxidant power assay (FRAP) was estimated according to the method of Oyaizu, cupric ion reducing capacity assay (CUPRAC) was estimated in accordance to the method of Apal. Mineral analysis was determined using Jenway 6100 Atomic Absorption Spectrophotometer. The physical properties which were also analysed are mass, density, hydration capacity, hydration index, swelling capacity, swelling index. The four moisture content levels of the Mucuna seed indicates, ranging from 15% to 30% moisture content level, crude fibre (12.07%-12.34%), ash remains constant (5.01%), crude lipid (3.11%-3.50%), crude protein (24.91%-23.91), carbohydrate (54.9%-55.2%), caloric value (347.21Kcal/100g-348.12Kcal/100g). The minerals composition ranging from 15% to 30% moisture content level gave the data that mucuna seeds contained calcium (Ca) (5.28mg/g-5.30mg/g), iron (Fe) (0.96mg/g-0.97mg/g), potassium (K) (0.19mg/g-1.55mg/g), magnesium (Mg) (1.65mg/g-1.68mg/g), phosphorus (P) remains constant (0.02mg/g), zinc (Zn) (0.26mg/g-0.27mg/g). Anti-nutrient ranging from 15% to 30% moisture content level, hydrogen cyanide (HCN) (0.23mg/g-0.26mg/g), oxalate (Ox) 0.033mg/g-0.037mg/g), phytate (P) (0.81mg/g-0.63mg/g), tannin (Ta) (1.51mg/g-1.50mg/g). Anti-oxidant ranging from 15% to 30% moisture content level, 1,1-diphenyl-2-picryllydrazyl (DPPH) (0.57%-0.95%), cupric ion reducing capacity assay (CUPRAC) (1.09%-0.31%), ferric ion reducing anti-oxidant power assay (FRAP) (1.27%-1.17%). The result for physiochemical properties of the Mucuna seed showed that the mass of 34 seeds (253.78g), density of 34 seeds (0.829g/m3), hydration capacity of 34 seeds (0.877kJ/m), hydration index (0.00346), swelling capacity of 34 seeds (0.0067g/mm3), swelling index (0.000886g). This study concluded that the tested Mucuna seed contained highest amount of carbohydrate and lowest amount of fibre, also it has highest amount of calcium in minerals, lowest amount of oxalate and highest amount of ferric ion reducing anti-oxidant power assay in anti-oxidant.
