ISOLATION AND IDENTIFICATION OF WAX ESTERS IN PALM OIL MILL FINAL EFFLUENT DISCHARGE

OOI Tian Lye* and M C Chow*

ABSTRACT

Thin layer chromatography of an extract of palm oil mill final effluent discharge revealed that the major components present are quite similar to those of crude palm oil. A band which had been previously reported and which contributed about 6% (w/w) of the extract was found to consist of long-chain wax esters ranging from molecular weight m/z 396 to m/z 508. Hexadecyl laurate and hexadecyl myristate were found to be the two major constituents; together they accounted for about 45% of the total was esters detected.

ANTIOXIDANT ACTIVITIES OF PALM VITAMIN E WITH SPECIAL REFERENCE TO TOCOTRIENOLS

The antioxidant activities of palm vitamin E and tocotrienols (T3) from Elaeis guineensis were investigated in model systems using distilled palm methyl ester (DME) and vitamin E-free RBD palm olein respectively. Oxidative stability was measured by the Rancimat method. Addition of 500 ppm vitamin E concentrate, which consisted of α-tocopherol (21.9%), α-tocotrienol (31.1%), γ-tocotrienol (37.7%) […]

IDENTIFICATION OF VOLATILE COMPOUNDS THAT CONTRIBUTE TO THE AROMA OF FRESH PALM OIL AND OXIDIZED OIL

Crude and oxidized palm oil were steam-distilled in vacuo to obtain volatile aroma compounds. The steam distillate was then extracted continuously using dichlorimethane and the extract was concentrated. The concentrate was analysed using gas chromatography; identification of compounds was by mass spectrometry. The steam disstillate from cride palm oil contained compounds such as 2,2,6-trimethylcyclohexanone, 3,3,5-trimethylcyclohex-2-enone, […]
