ABSTRACT

A series of GRAS polyglycerol esters (PGE) has been produced and investigated for improving the dry fractionation of palm oil. Results show that the hydrophobic PGE can reduce the fractionation time and hence the energy consumed during fractionation. This will help to increase throughput for the process and the overall carbon footprint as a result of reducing energy use in the process. The fractionated oleins also exhibited better cloud points of between 7°C and 8°C, and an average iodine value of 57 Wijs. Crystal size was observed to be homogeneous, with the majority of the crystal sizes being in the range of 100 to 300 microns. It was also observed that this crystal size posed no filtration difficulty, as evidenced by the 76% to 78% olein yield obtained during pressing with a squeezing pressure of 5 bars. The stearins obtained were medium hard with iodine values between 33 and 35 Wijs, and slip melting points between 52°C and 53°C.

ISOLATION AND FUNCTIONAL PROPERTIES OF HEMICELLULOSES FROM OIL PALM TRUNKS

Approximately 80% (dry weight) of the total hemicelluloses (xylan) was extracted from oil palm trunks (OPT). Analysis of OPT gave the following composition (dry basis): 42%-45% cellulose, 26%-29% hemicellulose and 16%-18% lignin. Optimisation of the aqueous extraction was done using the following parameters: 3.0 M alkali concentration, 40°C temperature, 4 hr soaking time, 50 g […]

PERFORMANCE OF TENERA OIL PALM POPULATION DERIVED FROM CROSSES BETWEEN DELI DURA AND PISIFERA FROM DIFFERENT SOURCES ON INLAND SOILS

FELDA Agricultural Sdn Bhd (FASSB) has been exploiting various germplasm and advanced materials to broaden the narrow genetic base of its breeding population since 1968. The utilisation of these materials has resulted in more than 200 progeny test trials. From a total of 25 progenies analysed in this study, performance tended to group the teneras, […]
