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

Malaysia has conducted research on renewable fuel. Methyl ester, derived from palm oil through an esterification process, has proven to be suitable for unmodified diesel engines. Hence, a test on this fuel or its derivative is a prerequisite before it can be fully used in the engine. Fuel testings are normally required to meet increasing … Read more
