Research ArticleOpen accessEvery word in the titleInduced Production of α-Tocotrienol by Co-Suppression of Tocopherol Cyclase Gene in Vegetable CropsUmaiyal Munusamy, Siti Nor Akmar Abdullah, Maheran Abdul Aziz et al.This study involves the induced production of α-tocotrienol by the co-suppression of tocopherol cyclase gene. The Tocopherol/Tocotrienol Cyclase (TC) is a key enzyme involved in the biosynthesis of α-tocotrienol. The partial conserved cDNA of TC gene isolated from the oil palm (Elaeis guineensis) that shared greater than 75% sequence identity with TC sequences from other plant species was used to … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,706 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleThe 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 keywordsVitamin E and Beta Carotene Composition in Four Different Vegetable OilsAb. Gapor Md. Top, Halimah Muhamad, Aminah Abdullah et al.Problem statement: Some vegetable oils contains natural antioxidants such as beta carotene and vitamin E namely tocopherol and tocotrienol. Different vegetable oils contained different amount of vitamin E and β-carotene. Approach: Study was carried out to investigate the natural antioxidants (vitamin E and beta carotene) composition in four different vegetable oils [Red Palm Olein (RPO), palm plein (PO), Corn Oil … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 9,316 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGermination Time Dependence of Bioactive Compounds and Antioxidant Activity in Germinated Rough Rice (Oryza sativa L.)Anuchita Moongngarm, Ekkalak KhomphiphatkulProblem statement: Germinated rice has been recognized as a functional food and its health benefits. However, most related studies were on germinated brown rice but our previous study indicated that germination of rough rice was an effective method to obtain high concentrations of bioactive compounds. Germination time is one of the most important factors affecting the level of biochemical compositions … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 8,663 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProduction 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
