Abstract

Effect of sun drying, soaking, boiling and fermentation processes on the level of some anti nutrients present in the seeds and pulp of premature and mature fruits of pilio stigma thonningii were studied. Comparing with other treatments, fermentation had the least (reduction) of trypsin-inhibitor in the seeds regardless of its duration. Boiling and fermentation significantly (p<0.05) reduced cyanide by (41.6- 47.9%), phytate by (65.7 - 74.3%), saponin by (33.1 - 45.2%) and oxalate by (33.7 - 84%). However, the combined effect of boiling and fermentation processes has the potential of removing most anti nutrients from the seeds and the pulp of the fruits of Piliostigma thonningii to a minimal level. Reduction to safe level of the anti nutrients is essential to improve the nutritional quality of the seeds and the pulp of the fruits of Piliostigma thonningii and for effective utilization of its full potentials as a novel food for animals and human.
