Abstract

To comparatively study the effect of aluminium phosphide preservative on some nutrientional and anti-nutritional factors in Arachis hypogaea. Study Design: Randomized design Place and Duration of Study: Department of Biochemistry and Molecular Biology Laboratory, Nasarawa State University, Keffi between May and August, 2019. Methodology: Two portions of A. hypogaea weighing 500g each, were obtained, one portion preserved with Aluminium phosphide tablet while the second portion was without any preservative. The preservation lasted for 30 days after which the A. hypogaea was blended using a mechanical blender before analysis for nutritional and anti-nutritional compositions. Result: The proximate compositions were significantly (p<0.05) higher in the NAPP 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). Carbohydrates (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/100g; 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±0.06mg/100g; 63.00±0.06mg/100g), 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±0.06mg/100 g; 26.20±0.06mg/100g), manganese (26.02±0.06mg/100g; 15.10±0.06 mg/100 g), magnesium (11.00±0.06mg/100g; 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±.60 mg/100 g), phytate (16.72±0.60 mg/100 g; 5.48±0.60 mg/100 g), alkaloid (16.72±0.60 mg/100g; 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). Conclusion: 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.
