Research ArticleOpen accessIn the author namesProduction of Palm Oil with Methane Avoidance at Palm Oil Mill: A Case Study of Cradle-to-Gate Life Cycle AssessmentChiew Wei Puah, Yuen May Choo, Soon Hock OngThe study discusses a case study of cradle to gate life cycle assessment for the production of Crude Palm Oil (CPO) with methane avoidance at palm oil mill. The improved milling process enables total utilization of the oil palm fruit to produce alow oil palm based food source. The minimal modification in the mill includes cleaning of Fresh Fruit Bunches … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 9 Sep 2013 · 7,387 accessesView PDF Cite

Research ArticleOpen accessIn the author namesThe Effect of Physical Refining on Palm Vitamin E (Tocopherol, Tocotrienol and Tocomonoenol)Chiew Wei Puah, Yuen May Choo, Ah Ngan Ma, Cheng Hock ChuahThis study reports the effect of physical refining on palm vitamin E including α- tocopherol, α-, γ and α-tocotrienols as well as α- tocomonoenol. A method using HPLC with fluorescence detector using normal phase silica column is described. An isocratic elution with n-hexane/THF/2-propanol (1000:60:4, by vol.) as mobile phase was used. The structure of the α- tocomonoenol was determined using … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,362 accessesView PDF Cite

Research ArticleOpen accessIn the author namesSupercritical Fluid Extraction of Palm CarotenoidsPuah C. Wei, Choo Y. May, Ma A. Ngan, Chuah C. HockThe extraction of carotenoids from crude palm oil was carried out in a dynamic (flow- through) supercritical fluid extraction system. The carotenoids obtained were quantified using off-line UV-visible spectrophotometry. The effects of operating pressure and temperature, flow rate of the supercritical carbon dioxide (SC-CO2), sample size of feed used on the solubility of palm carotenoids were investigated. The results showed … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,762 accessesView PDF Cite
