Book Description
The objectives of this study were to develop fast, accurate, low cost, sensitive and environmentally friendly analytical methods for selected quality factors and minor components in edible oils and fats and their associated products using Fourier Transform Infrared (FTIR) spectroscopy. These analyses include soap residues in the chemically refined vegetable oils, quantifying hexane residues in the solvent extracted vegetable oils, detection of aflatoxins in groundnut and groundnut cake, the determination of malondialdehyde (MDA) as one of the thiobarbituric acid reactive substances (TBARS) in edible oils, the determination of minor components in edible oils such as sesamol and gossypol in sesame seed and cottonseed oils, respectively. In addition, the FTIR techniques were also be used to determine the adulteration of sesame seed oil with other vegetable oils and lard in body fats of chicken, lamb and cow.

Book Description
Standard Methods for the analysis of Oils, Fats and Derivatives Sixth Edition, Part 1 (Sections I and II) describes the methods of analysis, which have been adopted and edited by the Commission on Oils, Fats and Derivatives. This book is composed of two sections. The first section deals with the presentation of standard methods and procedure for oleaginous seeds and fruits analysis of oil, fats, and their derivatives. The next section describes the determination procedure of physico-chemical properties of determined oil, fats, and derivatives. Such characteristics include density, refractive index, color, dilatation, acid, ester, iodine value, and moisture and volatile matter content This book will prove useful to analytical chemists and researchers in the allied fields.

Book Description
For several years, a variety of spectrographic methods has been used by railroad and petroleum laboratories for the determination of wear metals in used diesel locomotive crankcase oils. These methods have, in general, met the needs of individual laboratories, since each method is fairly self-consistent and therefore useful in detecting any major change in the metal content of the lubricant. For the purpose of monitoring a particular locomotive over a period of time, apparently any one of numerous methods might be employed with satisfactory results. However, with the rapid adoption of spectrographic analysis of used oils, there came the inevitable necessity of comparing the results of one laboratory with another, and one method with another. Opposing methods were found to provide distinctly different absolute values within a given laboratory, and a single method could seldom be made to reproduce results from laboratory to laboratory. With this situation existing in early 1951, ASTM Committee D-2 on Petroleum Products was asked to investigate the possibility of standardizing spectrographic procedures for the analysis of used diesel locomotive crankcase oils. Within ASTM Committee D-2, the assignment falls under the jurisdiction of Research Division III on Elemental Analysis, and has become the major responsibility of Section J of Research Division III. Section J has a membership of approximately 40 representatives of petroleum, railroad, and locomotive manufacturing laboratories.

Book Description
This book contains papers from the symposium "Critical Issues, Current and Emerging Technologies for Determination of Crude Fat Content in Food, Feed and Seeds," held in 2003 at the AOCS Annual Meeting in Kansas City, Missouri. The topics covered give a broad perspective of the challenges and issues of the value-added enhanced products. This book w
