Four high yielding and early maturing cultivars of pigeon pea (Cajanus cajan) namely UPAS-120, ICPL-87, ICPL-151 and, especially, Manak, contained significant amounts of polyphenols (1075 to 1328 mg/100g), which may limit their utilization. The effectiveness of soaking (6, 12 and 18 h, 30°C), soaking and dehulling, ordinary cooking, pressure cooking and germination (24, 36, 48 h, 30°C) in reducing the levels of polyphenols was investigated. A decrease in the polyphenolic contents varying from 4 to 26 percent in different pigeon pea cultivar was achieved. Pressure cooking of soaked-dehulled seeds was found to be the most effective method, followed by sprouting for 48 h, ordinary cooking of soaked-dehulled seeds, and pressure cooking of soaked whole seeds followed by sprouting for 36 h.
