Commercially used for food flavorings, toiletry products, cosmetics, and perfumes, among others, citrus essential oil has recently been applied physiologically, like for chemoprevention against cancer and in aromatherapy. Citrus Essential Oils: Flavor and Fragrance presents an overview of citrus essential oils, covering the basics, methodology, and applications involved in recent topics of citrus essential oils research. The concepts, analytical methods, and properties of these oils are described and the chapters detail techniques for oil extraction, compositional analysis, functional properties, and industrial uses. This book is an unparalleled resource for food and flavor scientists and chemists.

Essential Oils in Food Preservation, Flavor and Safety discusses the major advances in the understanding of the Essential Oils and their application, providing a resource that takes into account the fact that there is little attention paid to the scientific basis or toxicity of these oils. This book provides an authoritative synopsis of many of the complex features of the essential oils as applied to food science, ranging from production and harvesting, to the anti-spoilage properties of individual components. It embraces a holistic approach to the topic, and is divided into two distinct parts, the general aspects and named essential oils. With more than 100 chapters in parts two and three, users will find valuable sections on botanical aspects, usage and applications, and a section on applications in food science that emphasizes the fact that essential oils are frequently used to impart flavor and aroma. However, more recently, their use as anti-spoilage agents has been extensively researched. Explains how essential oils can be used to improve safety, flavor, and function Embraces a holistic approach to the topic, and is divided into two distinct parts, the general aspects and named essential oils Provides exceptional range of information, from general use insights to specific use and application information, along with geographically specific information Examines traditional and evidence-based uses Includes methods and examples of investigation and application

Essential oils have been the key natural raw material in flavor and fragrance industry since its inception (Dugo et al., 2002). Citrus essential oil, as the largest essential oil group, comprises 70% of imported oils in US (Dugo et al., 2002). Their unique sensory properties have been widely accepted and applied in beverage, confectionary, perfume, house care and other fields. However, due to relatively simple chemical composition and tremendous price differences among citrus species, unscrupulous players have been tempted to practice adulteration in citrus oils for a long time. Addition of key aromatic chemicals into low-grade stripped oil or oil fractions is one way to lower the oil cost. Extending high quality citrus oil with oil fractions from a cheaper source is also taking place on regular basis. As they become increasingly sophisticated, perpetrators are capable of making blends that are almost indistinguishable from authentic oils through conventional GC analysis. As a consequence, essential oil industry is demanding definitive, sensitive, and efficient approaches to grade commercial citrus oils and keep adulterated oil from entering the finished products. A reversed-phase HPLC method was developed for compositional study of essential oils from major citrus species (i.e., orange, mandarin, tangerine, lemon, lime, and grapefruit). Majority of the oxygenated heterocyclic components in citrus oils were identified by HPLC-MS and confirmed by previous literatures. Two hydroxylated PMFs (polymethoxyflavone) have been identified from cold pressed orange and tangerine oils for the first time. A comprehensive database of major PMF compounds is built with data collected from a large pool of industrial orange, tangerine and mandarin oil samples. Numerical ranges of PMF compounds for sample approval were extrapolated from the database. Meanwhile, principle components analysis (PCA) was carried out for sample classification. Based on the numerical limits and statistical analysis results, detailed information regarding the origin and history of oil samples can be revealed. Similar study will be performed on lemon, lime and grapefruit oil samples as well. The author is hoping this analysis procedure will be serving as a routine quality control test for authenticity evaluation and adulteration detection in citrus essential oils.

This 6th edition is thoroughly revised and updated, and now additionally includes all commercially important flavor and fragrance materials that entered the market over the past 10 years. In one handy and up-to-date source, this classic reference surveys those natural and synthetic materials that are commercially available, produced, and used on a relatively large scale, covering their properties, manufacturing methods employed, and areas of application. For this new edition the chapter on essential oils has been completely revised with regard to production volumes, availability, and new product specifications, while new legal issues, such as REACH regulation aspects, are now included. Finally, the CAS registry numbers and physicochemical data of over 350 single substances and 100 essential oils have been updated and revised.

"The book contains twenty three chapters written by experts on the subject is structured in two parts: the first one describes the role of the latest developments in analytical and bioanalytical techniques, and the second one deals with the most innovative applications and issues in food analysis. The two first introductory chapters about sampling technique, from basic one to the most recent advances, which is still a food challenge because is responsible of the quality and assurance of the analysis, andon data analysis and chemometrics are followed by a review of the most recently applied techniques in process (on-line) control and in laboratories for the analysis of major or minor compounds of food. These techniques ranged from the non-invasive and non-destructive ones, such as infrared spectroscopy, magnetic resonance and ultrasounds, to emerging areas as nanotechnology, biosensors and electronic noses and tongues, including those already well-established in food analysis, such as chromatographic andelectrophoretic techniques. These chapters also include two important tools for solving problems in chemical and biological analysis such as mass spectrometry and molecular-based techniques"--

With the development of synthetic organic chemistry techniques in the early 19th century the world of synthetic FandF materials began and expanded, but it has not totally replaced natural FandF. A growing segment of the public prefers natural foods to foods containing artificial additives, and will pay a premium for natural foods. While modern synthetic methods permit the economical production of artificial FandF on a large scale, the natural FandF industry remains important. Why is thisso? How do the chemical, biological, and agricultural sciences support the natural FandF industry? What is the state of current natural FandF research? These are questions this volume attempts to address. Even considering only the value of FandF derived from essential oils, natural FandF constitute approximately a $2 billion annual business. The impact of FandF is best appreciated when you consider that a flavor or fragrance typically contributes only a very small part, both in cost and volume, to a finished product. Many analytical tools available do not have a detector that is as sensitive to taste or odor as a human (or many animals for that matter). The challenge for researchers is to sift FandF information from all the data obtained from the various analytical techniques. The intent of this book is to give the reader and appreciation for the many facets of the chemistry, analysis and production of natural flavors and fragrances. It is a field where each one of us who can smelland taste are active participants. New foods, plants, processes, packages and aromas are developed each day. Keeping researchers abreast of the many new facets of the natural FandF field have led to development of this chapter and the ACS symposium that served as the basis of this book.
