Qualitative Objectives of Oil Refining
• Complete removal or reduction of undesired constituents to tolarable limits to preserve quality attributes of oils.
• Removal of contaminants for food safety (PAH, pesticides,etc.)
• Maximum retention of tocopherols and sterols in refined oils
• Prevention of undesired reactions (conjugation, trans formation etc.) together with elimination of process contaminants (3‐MCPD and esters)
