The Chemical Story of Olive Oil


Book Description

Despite the growing interest in olive oil, most people know very little about what it is or how it is made. This book provides a comprehensive treatment of olive oil from the tree to table, from a molecular and personal perspective. Growers often do not know what is happening at a molecular level or why certain practices produce superior or inferior results, for example, why adjusting a temperature rewards them with winning oils. This book aims to provide some of the answers as well as the importance of the chemicals responsible for the flavour and health effects. Readers will also get a deeper understanding of what makes an extra virgin olive oil authentic and how scientists are helping to fight fraud regarding this valuable commodity. Including anecdotes from growers of olives and producers of oils, the authors provide an accessible text for a wide audience from food science students to readers interested in the human story of olive oil production.







Extra Virginity


Book Description

The sacred history and profane present of a substance long seen as the essence of health and civilization. For millennia, fresh olive oil has been one of life's necessities-not just as food but also as medicine, a beauty aid, and a vital element of religious ritual. Today's researchers are continuing to confirm the remarkable, life-giving properties of true extra-virgin, and "extra-virgin Italian" has become the highest standard of quality. But what if this symbol of purity has become deeply corrupt? Starting with an explosive article in The New Yorker, Tom Mueller has become the world's expert on olive oil and olive oil fraud-a story of globalization, deception, and crime in the food industry from ancient times to the present, and a powerful indictment of today's lax protections against fake and even toxic food products in the United States. A rich and deliciously readable narrative, Extra Virginity is also an inspiring account of the artisanal producers, chemical analysts, chefs, and food activists who are defending the extraordinary oils that truly deserve the name "extra-virgin."







Characterization and Authentication of Olive and Other Vegetable Oils


Book Description

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. 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.




Products from Olive Tree


Book Description

Olive tree products provide a number of documented presentations of the production and quality of the two most important olive tree products: virgin olive oil and table olives. It is a source that familiarizes readers with recent approaches and innovations that can be introduced in the virgin olive oil extraction and stabilization technology and the preparation of table olives with emphasis on the presence of bioactive constituents. It also describes advances in the methods of checking authenticity and in the evaluation of attributes that may influence consumers' perceptions and preferences. Other topics discussed are squalene, a trove of metabolic actions, pigments, geographical indication, biotechnology in table olive preparation, and recovery of hydroxytyrosol from olive-milling wastes.
