Modification of carotenoid content especially towards increasing lycopene content is one of the main targets of the oil palm genetic engineering programme at the Malaysian Palm Oil Board (MPOB) (Parveez et al., 2003). This is due to the potential nutraceutical properties of lycopene. It has been shown that this carotenoid has the greatest ability of … Read more
Modulating endogenous levels and/or production of novel fatty acid of oils has gained significant attention in recent years due to the increasing awareness by consumers of the impact that dietary lipids have on health. Commodity palm oil is composed of four main fatty acid: palmitic acid, stearic acid, oleic acid and linoleic acid. The percentage … Read more
Fertiliser is an important input in oil palm plantations, and has to be managed efficiency depends on the source type of fertiliser, method of placement, rate, frequency and timing of application. Previous work shows that application of fertiliser by general broadcast on clear-weeded circles, over the frond stack and outside the edge of the palm … Read more
The vermicomposting process has been described as the bio-oxidation and stabilisation of ooranic materials involving the hoint actions of earthworms and microorganisms (Aira et al., 2002). In contrast to traditional compost, vermicompost never heats up much above the ambient temperature. Many practitioners combine the two techniques, initially doung a partial pre-composting at high temperatures, followed … Read more
Bio fertiliser production in the oil palm industry has so far cincentrated mainly on the wastes from palm oil mills, but has excluded the refinery waste discharged by the palm oil refineries (POR). There are now 59 POR, and the generation of SBE has increased to 240 000 t annually. For the past 30 years, … Read more
Method 1: CaF2 Cell Beer’s Law The sample which has been diluted with cylohexane is introduce into CaF2 cell and the mid infrared absorption spectrum is recorded. The absorbption spectrum is recorded. The absorbance of the typical absorption band for esters at about 1745 cm-1 is measured. The biodiesel content is then calculated with a … Read more
This test method describes a procedure using a gas chramotographic mass selective detector (GC-MSD) for the determination of 3-monochlioropropane-1,2-diol (3-M CPD) esters in an oil matrix. The 3-monochlioropropane-1,2-diol (3-M CPD) is one of the food-processing contaiminants under the chloropropanols group. Zelinkova et al. (2006) showed that the formation of 3-MCPD esters in oils is linked to … Read more
Water solubility, also known as aqueous solubility, is the maximum amount of a substance that can dissolve in water at equilibrium, at a given temperature and pressure. This parameter is used in many environmental studies to help determine the fate of chemicals in the environment. Water solubility has been correlated to the partition coefficient, another … Read more
R&D in adsoption and catalyst characterisation has begun to gain interest in material science. With the development of advanced carbon technology, products like activated carbon, carbon molecular sieve, carbon fuel cell and nano-carbon can be made from lignocellulosic materials; including oil palm biomass. Activated carbon (AC) is a form of carbon that has been processed … Read more
Solid fat content (SFC) determination is of prime importance in food processing and product development of fats and fat-based products as their melting profiles need to be characterised. Pulsed Nuclear Magnetic Resonance (pNMR) is widely used for the measurement of SFC in oils and fats determination by TD-NMR (Time-Domain NMR) has long been recognised as … Read more
