castor oil - benefits for healthier life

Castor oil is extracted from castor beans by a cold-pressing technique, which uses a hydraulic press for extraction. It is also prepared through mechanical pressing, solvent extraction, or a combination of both pressing and extraction methods.

The ripe-harvested seeds are allowed to dry so that seed hull splits open and releases the seed. The seeds are then cleaned, crushed, and dried prior to oil extraction.

They are cooked so as to coagulate the protein which allows efficient extraction and pressing.

Finally, the extracted oil is filtered. The material removed from the oil is fed back again into the mainstream with fresh material. The discharged material is pressed in the form of castor cake containing about 8-10% oil.
