Interesterification is performed either by chemical or enzyme catalysis and involves at least two oils that have different fatty acid compositions. In chemical interesterification, alkali metals (sodium, potassium) and alkali-metal alcoholates (e.g., methylate, ethylate) are used as catalysts. Sodium methylate is the most widely used catalyst. The dried and deacidified oil is stirred at 80 to 100°C in the presence of alcoholate (0.1-0.3% of fat weight) and when the reaction is completed the catalyst is destroyed, by addition of water, and subsequently removed. The interesterified fat is recovered and then bleached and deodorized. Chemical interesterification progresses randomly with no regioselectivity (positional specificity) on the carbons of the glycerol moiety of the TAG (Gunstone, 1994).
