RAZALI, I.*; NORHAYA, H.*; NOR ASIMAH, A.S.*

ABSTRACT

Tertiary butyl hydroquinone (TBHQ),butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) were found to be the common antioxidants used in the palmoil industry.They are added to palm oil products either singly or in combination products either singly or in combination within the permissible limit of 200 parts per million. A procedure for the determination of the phenolic antioxidants which is based on the AIIBP method using a single step methanolic extraction and reverse phase gradient elution by HPLC was proven to be very simple and reliable.
