Relationship between polymerised triacylglycerols formation and tocopherols degradation was studied during heating of four commercially accessible vegetable oils (rapeseed oil, classical sunflower oil, soybean oil and olive oil) on the heating plate with temperature 180°C. The content of polymerised triacylglycerols 6% (i.e. half of maximum acceptable content) was achieved after 5.3, 4.2, 4.1, and 2.6 hours of heating for olive oil, soybean oil, rapeseed oil and sunflower oil, respectively, while decrease in content of total tocopherols to 50% of the original content was achieved after 3.4, 1.6, 1.3, and 0.5 hours of heating for soybean oil, rapeseed oil, sunflower oil and olive oil, respectively. Because of the high degradation rate of tocopherols, decrease in content of total tocopherols to 50% of the original content was achieved at content of polymerised triacylglycerols 0.6%, 1.9%, 2.8% and 4.9% for olive oil, rapeseed oil, sunflower oil and soybean oil, respectively, i.e. markedly previous to the frying oil should be replaced.

Biodiesel is clear liquid with a light to dark yellow color. Biodiesel is one of the alternative fuels that are attractive because of its favorable characteristics such as being non-toxic, biodegradable, renewable, carbon neutral and low emission. Fatty acid methyl ester (FAME) is a type of biodiesel. In this study, it was produced by using transesterification of waste cooking oil (WCO) which was reacted with methanol and heterogeneous catalyst. The two heterogeneous catalysts that were used in this study were sodium (Na) metal hydroxide supported on oil palm frond (OPF) and Na metal supported on oil palm kernel shell (OPKS). The support metal used was sodium hydroxide solution (NaOH). OPF and OPKS were used as they are the major residues obtained from the oil palm plantation that covers approximately 14.72% of Malaysian’s total landmass. The parameters that in this study were the reaction temperatures of the transesterification process from 30°C to 60°C and the catalyst loading from 0.5wt% to 3wt%. The reaction time and ratio methanol to oil were kept constant which were 4 hours and 1:10 respectively. This experiment was conducted in order to investigate the effect of two different heterogeneous catalysts on both temperature and catalyst loading on the yield production of FAME. The results were obtained by using GCMS analysis. From the experiment that was conducted, the results of FAME production by using two different catalysts indicate that the higher the reaction temperature is, the higher the production of FAME which is at 60°C. It also shows that the percentage yield of FAME increases with the increase of catalyst loading until it reaches the best value which is at 1wt%.

Abstract It is well known that biodiesel from pure coconut oil is suited best for diesel engine operation. However, the commercialization of coconut oil biodiesel is unfeasible due to its higher cost and demand as a food material. In this study, biodiesels were produced from coconut testa oil and coconut waste cooking oil, two waste feedstock derivatives of coconut. Fatty acid composition and properties such as density, calorific value, kinematic viscosity, cloud and pour points, flash and fire points, Conradson carbon residue, and copper strip corrosion of these two biodiesels were determined and compared with those of fresh coconut oil biodiesel and the standard diesel. It was found that the properties and fatty acid profiles of all three biodiesels were similar. Furthermore, from the engine testing using B20 (diesel-biodiesel blend with 20% biodiesel) blends of prepared biodiesels, it was found that the engine performance, emission, and combustion characteristics were comparable for coconut testa oil and coconut waste cooking oil biodiesels with fresh coconut oil biodiesel. Thus the coconut testa oil and coconut waste cooking oil can be used as low-cost feedstocks for biodiesel production with all advantages of fresh coconut oil.
