Deodorization is done to remove the volatile components, mainly Aldehydes & Ketones, with threshold values for dictation by taste or smell. Deodorization is essentially a steam distillation process carried out at low pressure 2-6 Kg/Cm2 and elevated temp range of 180-220°C.
The entire process is done under high vacuum. The smell is removed in the deodorizer. The FFA is also removed in the Physicaltype deodorizer.
