Book Description
Cis-Trans Isomeric Carotenoids, Vitamins A, and Arylpolyenes focuses on the reactions, characteristics, and properties of cis-trans isomeric carotenoids, vitamins A, and arylpolyenes. The publication first takes a look at carotenoids, number, types, and properties of cis carotenoids, and cis-trans isomerism and UV spectra. Discussions focus on simple theoretical interpretation of spectral phenomena, spectra at extremely low temperatures, relative stabilities, melting points, rotatory power, and historical remarks on the stereoisomerism of polyenes. The text then ponders on the preparation of cis carotenoids by direct rearrangement of the all-trans form and total synthesis and naturally occurring cis and polycis carotenoids. The manuscript examines some general remarks on configurational assignments, configurational assignments in certain stereoisomeric sets, and lower-molecular weight carotenoid-carboxylic acids. Topics include bixin set, stereoisomeric sets with two aromatic terminal groups, stereoisomeric sets with one hydroaromatic and one aliphatic terminal group, configuration and infrared spectrum, and stereoisomeric types. The manuscript also elaborates on vitamins A and retinenes, cumulenes with aromatic terminal groups, and polyene azines. The publication is a dependable source of information for researchers interested in cis-trans isomeric carotenoids, vitamins A, and arylpolyenes.

Book Description
The Carotenoids book series provides an introduction to the fundamental chemistry, detailed accounts of the basic methods used in carotenoid research, and critical discussions of the biochemistry, functions and applications of carotenoids. Part 1 discusses the fundamental properties on which the biological functions and effects of carotenoids depend. Part 2 describes important natural functions of carotenoids in all kinds of living organisms.

Book Description
In the mid-1960's, scientists working on carotenoids throughout the World agreed to have periodic meetings for the purpose of discussing and disseminating scientific research results concerning all aspects of carotenoids. The meetings were also organized to act as teaching forums for students, and the major scientific results from each meeting were to result in a publication. Each meeting was planned to be International in scope, being held in different locations in the World, and organized by local, recognized carotenoid scientists. The first of the Carotenoid meetings was held in Trondheim, Norway in 1966. Meetings then followed in Las Cuces, New Mexico (1969); Cluj, Roumania (1972); Berne, Switzerland (1975); Madison, Wisconsin (1978); Liverpool; England (1981); and Munich, Federal Republic of Germany (1984). In all of these meetings, the original purposes which stimulated the first meeting were accomplished: scientific discussion, student education and resulting scientific publication.The meetings and the i~formation resulting from them have led to significant advances in carotenoid biochemistry, biology, and chemisty. This publication represents the contributions from a distinguished list of participants. We look forward to the future meetings in this series.

Book Description
Fruits and fruit based products are, in most cases, associated with very good sensory characteristics, health, well-being, perishability, relatively easy to mix with food products of diverse origin, amenable to be processed by conventional and novel technologies. Given the multiplicity of aspects whenever fruit preservation is considered, the editors took the challenge of covering in a thorough, comprehensive manner most aspects dealing with this topic. To accomplish these goals, the editors invited well known colleagues with expertise in specific disciplines associated with fruit preservation to contribute chapters to this book. Eighteen chapters were assembled in a sequence that would facilitate, like building blocks, to have at the same time, a birds-eye view and an in-depth coverage of traditional and novel technologies to preserve fruits. Even though processing took center stage in this book, ample space was dedicated to other relevant and timely topics on fruit preservation such as safety, consumer perception, sensory and health aspects. FEATURES: Traditional and Novel Technologies to Process Fruits Microwaves Ohmic Heating UV-C light Irradiation High Pressure Pulsed Electric Fields Ultrasound Vacuum Impregnation Membranes Ozone Hurdle Technology Topics Associated with Fruit Preservation Safety Nutrition and Health Consumer Perception Sensory Minimal Processing Packaging Unit Operations for Fruit Processing Cooling and Freezing Dehydration Frying
