This work reveals that fermentation method can be use to facilitate increase oil
yield from papaya seed. Harvesting at the unripe stage is not encouraged, if the seed is required for oil production. The seed, and the oil rich products obtained through fermentation may be useful for both biofuel and industrial purposes. The reasonable level of phytonutrients in the seed, and its products may account for its medicinal value. Carica papaya seeds possessed very low value of tannins, and oxalate. But, the phytate values were generally on the higher side that may be responsible for its medicinal value. Also, drying at 45-50oC can be recommended as an appropriate processing method for papaya seed to reduce its level of wastage because it does not negatively affect its phytochemical and biochemical properties.
