Abstract: The nutrients and anti-nutrients of freshly harvested Arachis hypogaea aluminium phosphide preserved (APP) non-aluminium phosphide preserved (NAPP) were investigated. The study aimed at determining the effect of aluminium phosphide on nutrients and anti-nutrients levels of legumes using A. hypogaea as a case study. The proximate composition, minerals profile and anti-nutrients were estimated using standard analytical methods. The proximate compositions showed that NAPP is significantly (p<0.05) higher than APP except the fiber (03.01±0.06 mg/100 g; 03.80±0.06 mg/100 g) and ash (01.00±0.06 mg/100 g; 02.23±0.06 mg/100 g) carbohydrate (07.40±0.06 mg/100 g; 03.48±0.06 mg/100 g), protein (19.93±0.06 mg/100 g; 14.94±0.06 mg/100), fat (74.60±0.06 mg/100 g; 68.08±2.75 mg/100 g), and moisture content (06.40±0.06 mg/100 g; 3.00±0.06 mg/100 g). Exception of phosphorus (65.00±0.06 mg/100 g; 63.00±0.06 mg/100 g), the minerals concentration was significantly (p<0.05) higher in NAPP compared to APP. Iron (76.20±0.06 mg/100 g; 62.00±0.06 mg/100 g), potassium (38.01±0.06 mg/100 g; 26.20±0.06 mg/100 g), manganese (26.02±0.06 mg/100 g; 15.10±0.06 mg/100 g), magnesium (11.00±0.06 mg/100 g; 06.00±0.06 mg/100 g), calcium (82.10±0.06 mg/100 g; 72.00±0.06 mg/100 g) and zinc (25.01±0.06 mg/100 g; 14.01±0.06 mg/100 g).The anti-nutritional factors showed significant difference (p<0.05) higher in tannin (9.33±0.69 mg/100 g; 1.90±0.02 mg/100 g), oxalate (32.50±0.60 mg/100 g; 42.50±0.60 mg/100 g), phytate (16.72±0.60 mg/100 g; 5.48±0.60 mg/100 g), alkaloid (16.72±0.6 mg/100 g; 5.48±0.60 mg/100 g) and saponins (40.74±0.60 mg/100 g; 38.20±0.60 mg/100 g) except cyanide (0.02±0.00 mg/100 g; 0.02±0.00 mg/100 g). The study showed that aluminium phosphide negatively affected the nutritional profile of A. hypogaea. Thus, the effect of aluminium phosphide should be further investigated in vivo.
