English | ISBN: 0813823919 | 2012 | 408 pages | PDF | 3 MB

Analysis of Antioxidant-Rich Phytochemicals
To quantify antioxidants in natural sources, the application of chromatography techniques with different detectors followed by skillful sample preparation is necessary. Analysis of Antioxidant-Rich Phytochemicals is the first book that specifically covers and summarizes the details of sample preparation procedures and methods developed to identify and quantify various types of natural antioxidants in foods. Focusing on the principle of quantification methods for natural antioxidants, the book reviews and summarizes current methods used in the determination of antioxidant-rich phytochemicals in different sources. Chapter by chapter, the distinguished team of authors describes the various methods used for analysis of the different antioxidant-rich phytochemicals – phenolic acids; carotenoids; anthocyanins; ellagitannins, flavonols and flavones; catechins and procyanidins; flavanones; stilbenes; phytosterols; and tocopherols and tocotrienols. Going beyond extensive reviews of the scientific literature, the expert contributors call on their accumulated experience in sample extraction and analysis to outline procedures, identify potential problems in dealing with different samples, and offer trouble-shooting tips for the analysis. Analysis of Antioxidant-Rich Phytochemicals covers the important food applications and health-promoting functions of the major antioxidant phytochemicals, presents general analysis principles and procedures, and systematically reviews and summarizes the various analytical methods necessary for each type of natural antioxidant in different food sources.

Characterization and Authentication of Olive and Other Vegetable Oils: New Analytical Methods by María Jesús Lerma García

English | 2012-08-01 | ISBN: 3642314171 | PDF | 237 pages | 5,2 MB

This thesis presents new methods for the characterization of vegetable oils, with focus in olive oil, according to geographical and botanical origin, genetic variety and other issues influencing product quality.

Characterization and Authentication of Olive and Other Vegetable Oils: New Analytical Methods
A wide variety of analytical techniques have been employed, such as various chromatographic techniques (different gas and liquid chromatography methods), an electronic nose, infrared spectroscopy and expert-panel evaluation. Several families of minor compounds, with interest as adulteration markers, have been used for method development, including tocopherols, sterols, phenolics, alcohols, proteins and others. Most methods have been enhanced by the application of multivariate chemometrics. The proposed analytical techniques are of interest to investigate fraudulent actions and practices which are detrimental to product quality.
