Pongamia pinnata Seed Oil

  • K. Thirugnanasambandham


Indian Beech tree (Botanical Name: Pongamia pinnata (L.) Pierre) is a deciduous legume that grows up to about 50–80 feet tall and is native to subtropical regions like India. Being a legume, it fixes nitrogen into the soil and is often used as a windbreak between fields on farms. It has a wide spreading canopy making and fragrant flowers making it ideal for ornamental shade applications. The oil obtained from Pongamia pinnata seed is non-edible due to bitter tasting flavonoids. The plant has pharmaceutical uses but is not poisonous to the touch like jatropha. It is insect resistant and there is mention of using the press cake as both insecticide and chicken feed. Due to the large availability of Pongamia pinnata seed in India, in this present study, an attempt was made to investigate the ultrasound-assisted extraction process to extract the oil from Pongamia pinnata seed under various operating conditions such as solvent to sample ratio, sonication time, temperature. Three factors, three-level central composite design (CCD) coupled with desired function methodology was used to optimize and model the extraction process. Optimum extracting conditions for the maximum oil yield were determined using numerical optimization technique. Under these conditions, 72% of oil was extracted. Results confirmed that sonication is efficient method to extract the oil from Pongamia pinnata seed.
