- WHAT IS
- A fatty acid with 18 carbon atoms and a double bond
- In great demand yielding a wide variety of chemical derivatives, essential for diverse applications.
- Although contributing a minuscule part of edible oil produced- Critically important to diverse industries esp. global specialty chemical industry
- Extraction of oil from castor seeds is done in a manner similar to that for most other oil seeds.
- IMPORTANT PARTS OF THE PROCESS
- The major operations involved include
- cleaning of the raw material
- Castor cake is obtained after the extracted oil is filtered after the physical impurities eliminated
- The first stage viz. Pre-Pressing a)employs high pressure continuous screw press – the expeller.
- The Extracted oil then filtered-residue transferred along with fresh raw material.
- Ripe seeds are dried, are split open and the seeds discharged.
The Multiple Stages are:
o Settling and Degumming of the Oil
Eliminates the aqueous phase from the lipids, also removing phospholipids
o Neutralization
Removes free fatty acids from the oil.
o Bleaching
Eliminates impurities that lend spurious colors, phospholipids and oxidation impurities.
o Deodorization
Removing odor from the oil.
Hexan is employed to extract the remaining oil
any impurities present are eliminated using a filter press by removing any water, dissolved gases and acids. The extracted oil is finally refined as the last step.
3.TYPES OF APPLICATIONS
- Critically important to global specialty chemical industry- sole commercial source for hydroxylated fatty acid.
