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 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.

Chemical Analysis of Food: Techniques and Applications reviews new technology and challenges in food analysis from multiple perspectives: a review of novel technologies being used in food analysis, an in-depth analysis of several specific approaches, and an examination of the most innovative applications and future trends. This book won a 2012 PROSE Award Honorable Mention in Chemistry and Physics from the Association of American Publishers. The book is structured in two parts: the first describes the role of the latest developments in analytical and bio-analytical techniques and the second reviews the most innovative applications and issues in food analysis. Each chapter is written by experts on the subject and is extensively referenced in order to serve as an effective resource for more detailed information. The techniques discussed range from the non-invasive and non-destructive, such as infrared spectroscopy and ultrasound, to emerging areas such as nanotechnology, biosensors and electronic noses and tongues. Important tools for problem-solving in chemical and biological analysis are discussed in detail. Winner of a PROSE Award 2012, Book: Honorable Mention in Physical Sciences and Mathematics - Chemistry and Physics from the American Association of Publishers Provides researchers with a single source for up-to-date information in food analysis Single go-to reference for emerging techniques and technologies Over 20 renowned international contributors Broad coverage of many important techniques makes this reference useful for a range of food scientists

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.
