A guide to the use of essential oils in food, including information on their composition, extraction methods, and their antioxidant and antimicrobial applications Consumers’ food preferences are moving away from synthetic additives and preservatives and there is an increase demand for convenient packaged foods with long shelf lives. The use of essential oils fills the need for more natural preservativesto extend the shelf-life and maintaining the safety of foods. Essential Oils in Food Processing offers researchers in food science a guide to the chemistry, safety and applications of these easily accessible and eco-friendly substances. The text offers a review of essential oils components, history, source and their application in foods and explores common and new extraction methods of essential oils from herbs and spices. The authors show how to determine the chemical composition of essential oils as well as an explanation of the antimicrobial and antioxidant activity of these oils in foods. This resource also delves into the effect of essential oils on food flavor and explores the interaction of essential oils and food components. Essential Oils in Food Processing offers a: Handbook of the use of essential oils in food, including their composition, extraction methods and their antioxidant and antimicrobial applications Guide that shows how essential oils can be used to extend the shelf life of food products whilst meeting consumer demand for “natural” products Review of the use of essential oils as natural flavour ingredients Summary of relevant food regulations as pertaining to essential oils Academic researchers in food science, R&D scientists, and educators and advanced students in food science and nutrition can tap into the most recent findings and basic understanding of the chemistry, application, and safe us of essential oils in food processing.

Essential oils are amongst the most complex samples an analyst can face in terms of the number of compounds involved. In many cases, minor components are of interest as they can impart a distinctive fragrance character to the oil. Because of the closely related structures and molecular weights among terpenes, positive identification of individual compounds is very difficult with a single chromatographic technique. Further, most of the analytical information is lost when a single technique is used because of the limited peak capacity and the resulting peak overlap. For many years, gas chromatography coupled to mass spectrometry (GC-MS) has been the benchmark technique for qualitative and quantitative analysis of essential oils. Retention indices and mass spectra have to be used in combination for confirmation of the identity of components in an essential oil. Other multidimensional or hyphenated techniques also offer advantages that aid in the identification of essential oil components. This thesis demonstrates the application of a comprehensively coupled supercritical fluid and fast temperature programmed gas chromatograph (SFCxGC) to the analysis of essential oils. An SFCxGC instrument was used to analyse the essential oils of Cymbopogon (lemongrass), Artemisia afra (wilde als), Tagetes minuta (kakiebos) and Pelargonium (geranium) species. The unique application of a porous layer open-tubular (PLOT) column, used in conjunction with supercritical carbon dioxide is demonstrated to effect group separation of polar, oxygenated compounds. This separation and elution of very polar compounds from a silica gel column is believed to occur due to the reduced phase ratio (??) of the system obtained by increasing the volume available to the mobile phase compared to that of a packed column. This separation obtained in the SFC is used to separate essential oils into different chemical classes such as non-polars, ethers, alcohols. Separated chemical classes are re-injected on-line by use of a modulator into a fast, second dimension, temperature programmed GC to effect separation of individual compounds based on their volatility. The entire sample is analysed by both the SFC and GC in such a way that the resolution obtained in the first dimension is conserved by the GC analyses. By using a range of standards, some of the peaks in these oils could be assigned. The identification of compounds was greatly aided by the combination of the two separation dimensions. The comprehensive two-dimensional technique arranges component peaks in a plane from which chemical class and volatility information of each component is readily obtained. The elution pattern within the two-dimensional chromatograms may also be used for direct comparison of oils without identification of the components in the essential oils.

Gas Chromatography involves the study of various vaporizable molecules in chemistry and the other related research fields. This analytical method has a number of features and advantages that make it an extremely valuable tool for the identification, quantification and structural elucidation of organic molecules. This book provides detailed gas chromatography information to applications of biochemicals, narcotics and essential oils. The details of the applications were briefly handled by the authors to increase their comprehensibility and feasibility. This guide should be certainly valuable to the novice, as well as to the experienced gas chromatography user who may not have the enough experience about the specific applications covered in this book. We believe this book will prove useful in most laboratories where modern gas chromatography is practiced.
