Keyword : superolein

Fractionation of palm oil yields olein (liquid) and stearin (solid) fractions. Further fractionation of the olein component yields double-fractionated olein and palm mid-fraction (PMF). The olein thus obtained is usually called superolein as it has a high Iodine Value (IV) and therefore has a lower cloud point.

At present, there is no international standard for superolein. Individual countries, therefore, may have their own standards.

Malaysian superolein (or double fractionated palm olein) is traded under the PORAM standards which are as follows:-

Free Fatty Acid (FFA) 0.1% max

Moisture & Impurities (M+I) 0.1% max

Iodine Value (IV) 60 min

Slip Melting Point (SMP) 19° max

Colour (5 1/4” Lovibond) 3 Red max
