摘要:The effect of some thermal processing techniques on the anti-nutritional factors of Canavaliaplagiosperma Piper seeds was studied. Raw seeds of Canavalia plagiosperma Piper (Oblique- seeded Jack bean) were autoclaved (at 121°C, 15 psi for 25, 30 and 35 minutes), cooked (at 100°C for 30, 40 and 50 minutes) and roasted (at 120°C for 40, 60 and 80 minutes). The anti-nutritional factors of the processed and raw samples were determined. Six (6) anti-nutrients (alkaloid: 1.17%, haemagglutinin: 20.31 Hu/mg, hydrogen cyanide: 4.70 mg/kg, raffinose: 0.64%, stachyose: 1.09%, steroid: 0.38%) were determined in the raw seed. The three processing treatments given to the seed showed a general reduction trend on these six anti-nutrients at different rates and levels. From the results, autoclaving was the best processing method for haemagglutinin (0.05 Hu/mg), raffinose (0.06%), stachyose (0.22%) and steroid (0.02%) while cooking was the best processing treatment for alkaloid (0.04%) and hydrogen cyanide (0.83 mg/kg). Roasting had the least reduction effect on the six anti- nutrients investigated. The results, therefore, suggest that moist heat treatments (autoclaving and cooking) significantly lowered the levels of antinutrients in Canavaliaplagiosperma Piper seeds, thereby making it safer for consumption.
