Determination of sulfur contents of vegetable and marine oils by ion chromatography and indirect ultraviolet photometry of their combustion products
Journal of the American Oil Chemists' Society - Tập 65 - Trang 1526-1530 - 1988
R. C. Wijesundera, R. G. Ackman, V. Abraham, J. M. deMan
A simple method for the determination of total sulfur content in vegetable and marine oils is described. The method involves combustion of the oil sample in an oxygen bomb to convert all forms of sulfur to sulfate ions with subsequent determination of the sulfate by ion chromatography and indirect ultraviolet detection. The ultraviolet system described is more sensitive than conductivity detection...... hiện toàn bộ

A method for the structural analysis of triglycerides and lecithins
Journal of the American Oil Chemists' Society - - 1963
O. S. Privett, Merle L. Blank
AbstractThe structural analysis of lecithins and triglycerides is described. The procedure is carried out on 2舑5 mg of sample by a combination of reductive ozonolysis and thin‐layer chromatography (TLC). The ozonides as well as the aldehyde 舠cores舡 derived from reduction of the ozonides are separated by TLC and analyzed quantitatively by densitometry. The constitue...... hiện toàn bộ

Aflatoxin inactivation: Treatment of peanut meal with formaldehyde and calcium hydroxide
Journal of the American Oil Chemists' Society - Tập 53 - Trang 204-206 - 1976
L. P. Codifer, G. E. Mann, F. G. Dollear
A peanut meal contaminated with ca. 600 ppb aflatoxins was treated with formaldehyde alone and in combination with calcium hydroxide in a benchscale reactor, operated both sealed and at atmospheric pressure. In general, thin layer chromatographic assays revealed that addition of calcium hydroxide to formaldehyde caused greater inactivation of the toxins than did formaldehyde alone. With the reacto...... hiện toàn bộ
A twin‐screw extruder for oil extraction: II. Alcohol extraction of oleic sunflower seeds
Journal of the American Oil Chemists' Society - - 1999
Corinne Dufaure, Zéphirin Mouloungui, Luc Rigal
AbstractOur work is about the extraction of sunflower seed oil in a twin‐screw extruder with or without the injection of 2‐ethylhexanol and acidified 2‐ethylhexanol. 2‐Ethylhexanol is mixed with phosphoric acid. The oil recovery is increased to 90% by the co‐injection of acidified alcohol. Mixing phosphoric acid with the alcohol enhances the lability of the oily sp...... hiện toàn bộ

The Effect of Natural and Synthetic Antioxidants on the Oxidative Stability of Biodiesel
Journal of the American Oil Chemists' Society - Tập 85 - Trang 373-382 - 2008
Haiying Tang, Anfeng Wang, Steven O. Salley, K. Y. Simon Ng
A significant problem associated with the commercial acceptance of biodiesel is poor oxidative stability. This study investigates the effectiveness of various natural and synthetic antioxidants [α-tocopherol (α-T), butylated hydroxyanisole (BHA), butyl-4-methylphenol (BHT), tert-butylhydroquinone (TBHQ), 2, 5-di-tert-butyl-hydroquinone (DTBHQ), ionol BF200 (IB), propylgallate (PG), and pyrogallol ...... hiện toàn bộ
