The assessment of nutritive and anti-nutritive compositions of fermented and unfermented seeds of Annona senegalensis from Niger State, Nigeria was carried out using standard analytical methods. The proximate parameters determined were moisture, protein, ash, fat and fibre of the unfermented seed were 18.07±0.03, 16.90±0.14, 3.62±0.23, 27.54±0.45 and 7.34±0.11%, respectively; while the moisture, protein, ash, fat and fibre of the fermented seed for 24 and 48 h were 21.00±0.51 and 22.78±0.21, 18.42±0.32 and 25.89±0.05, 4.00±0.50 and 4.22±0.32, 23.00±0.10 and 21.76±0.31, 5.35±0.16 and 4.05±0.14%. The carbohydrate content was lowest in the seed fermented for 24 h (21.30±0.46%) and highest in the unfermented seed (26.60±0.54%). Energy values obtained in this work were 1757.29±0.33, 1616.34±0.14 and 1573.35±0.52 Kcal/100g for the unfermented, 24 and 48 h fermented samples, respectively. The fermentation generally improved the mineral contents but decreased the anti-nutrient contents of the seeds. The amino acid profiles makes the studied seed protein of high nutritive. Thus, large-scale production of fermented A. senegalensis seeds will be a valuable source of nutrients for humans and animals.
